## Installation
### 1. The python distribution "*__Anaconda__*" is recommended:
The package was tested with the anaconda distribution and with **PYTHON>=3.7** under **Ubuntu 20.04** and **MacOS Big Sur**.
With Anaconda, it may be easier to install some required dependencies listed below, e.g., cartopy, using the _conda_ command.
It's also recommended installing the package and dependencies in a virtual environment with anaconda.
After [installing the anaconda distribution](https://docs.anaconda.com/anaconda/install/index.html), a virtual environment can be created by the code below in the terminal:
```shell
conda create --name [YOUR_ENV_NAME] -c conda-forge python cython cartopy
```
The package "spyder" is a widely-used python IDE. Other IDEs, like "VS Code" or "Pycharm" also work.
> **_Note:_** The recommended IDE is Spyder. Sometimes, a *RuntimeError* can be raised
> when the __aacgmv2__ package is called in **PyCharm** or **VS Code**.
> If you meet this issue, try to compile the codes in **Spyder** several times.
After creating the virtual environement, you need to activate the virtual environment:
```shell
conda activate [YOUR_ENV_NAME]
```
and then to install the package as shown below or to start the IDE **Spyder**.
More detailed information to set the anaconda environment can be found [here](https://conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#),
### 2. Installation
#### Quick install from the pre-built release (recommended):
```shell
pip install geospacelab
```
#### Install from [Github](https://github.com/JouleCai/geospacelab) (not recommended):
```shell
pip install git+https://github.com/JouleCai/geospacelab@master
```
### 2. Dependencies
The package dependencies need to be installed before or after the installation of the package.
Several dependencies will be installed automatically with the package installation,
including __toml__, __requests__, __bueatifulsoup4__, __numpy__, __scipy__, __matplotlib__, __h5py__, __netcdf4__,
__cdflib__, __madrigalweb__, __sscws__, and __aacgmv2__.
Other dependencies will be needed if you see a *__ImportError__* or *__ModuleNotFoundError__*
displayed in the python console. Some frequently used modules and their installation methods are listed below:
- [__cartopy__](https://scitools.org.uk/cartopy/docs/latest/installing.html): Map projection for geospatial data.
- ```conda install -c conda-forge cartopy ```
- [__apexpy__ \*](https://apexpy.readthedocs.io/en/latest/reference/Apex.html): Apex and Quasi-Dipole geomagnetic
coordinate system.
- ```pip install apexpy ```
- [__geopack__](https://github.com/tsssss/geopack): The geopack and Tsyganenko models in Python.
- ```pip install geopack ```
> ([\*]()): The **_gcc_** or **_gfortran_** compilers are required before installing the package.
> - gcc: ```conda install -c conda-forge gcc```
> - gfortran: ```conda install -c conda-forge gfortran ```
Please install the packages above, if needed.
Note: The package is currently pre-released. The installation methods may be changed in the future.
### 4. First-time startup and basic configuration
Some basic configurations will be made with the first-time import of the package. Following the messages prompted in the python console, the first configuration is to set the root directory for storing the data.
When the modules to access the online Madrigal database is imported, it will ask for the inputs of user's full name, email, and affiliation.
The user's configuration can be found from the *__toml__* file below:
```
[your_home_directory]/.geospacelab/config.toml
```
The user can set or change the preferences in the configuration file. For example, to change the root directory for storing the data, modify or add the lines in "config.toml":
```toml
[datahub]
data_root_dir = "YOUR_ROOT_DIR"
```
To set the Madrigal cookies, change the lines:
```toml
[datahub.madrigal]
user_fullname = "YOUR_NAME"
user_email = "YOU_EMAIL"
user_affiliation = "YOUR_AFFILIATION"
```
### 5. Upgrade
If the package is installed from the pre-built release. Update the package via:
```shell
pip install geospacelab --upgrade
```
### 6. Uninstallation
Uninstall the package via:
```shell
pip uninstall geospacelab
```
If you don't need the user's configuration, delete the file at **_[your_home_directory]/.geospacelab/config.toml_**
## Usage
### Example 1: Dock a sourced dataset and get variables:
The core of the data manager is the class Datahub. A Datahub instance will be used for docking a buit-in sourced dataset, or adding a temporary or user-defined dataset.
The "dataset" is a Dataset instance, which is used for loading and downloading
the data.
Below is an example to load the EISCAT data from the online service. The module will download EISCAT data automatically from
[the EISCAT schedule page](https://portal.eiscat.se/schedule/) with the presetttings of loading mode "AUTO" and file type "eiscat-hdf5".
Example 1:
```python
import datetime
from geospacelab.datahub import DataHub
# settings
dt_fr = datetime.datetime.strptime('20210309' + '0000', '%Y%m%d%H%M') # datetime from
dt_to = datetime.datetime.strptime('20210309' + '2359', '%Y%m%d%H%M') # datetime to
database_name = 'madrigal' # built-in sourced database name
facility_name = 'eiscat' # facility name
site = 'UHF' # facility attributes required, check from the eiscat schedule page
antenna = 'UHF'
modulation = 'ant'
# create a datahub instance
dh = DataHub(dt_fr, dt_to)
# dock the first dataset (dataset index starts from 0)
ds_isr = dh.dock(datasource_contents=[database_name, 'isr', facility_name],
site=site, antenna=antenna, modulation=modulation, data_file_type='eiscat-hdf5')
# load data
ds_isr.load_data()
# assign a variable from its own dataset to the datahub
n_e = dh.assign_variable('n_e')
T_i = dh.assign_variable('T_i')
# get the variables which have been assigned in the datahub
n_e = dh.get_variable('n_e')
T_i = dh.get_variable('T_i')
# if the variable is not assigned in the datahub, but exists in the its own dataset:
comp_O_p = dh.get_variable('comp_O_p', dataset=ds_isr) # O+ ratio
# above line is equivalent to
comp_O_p = dh.datasets[0]['comp_O_p']
# The variables, e.g., n_e and T_i, are the class Variable's instances,
# which stores the variable values, errors, and many other attributes, e.g., name, label, unit, depends, ....
# To get the value of the variable, use variable_isntance.value, e.g.,
print(n_e.value) # return the variable's value, type: numpy.ndarray, axis 0 is always along the time, check n_e.depends.items{}
print(n_e.error)
```
### Example 2: EISCAT quicklook plot
The EISCAT quicklook plot shows the GUISDAP analysed results in the same format as the online EISCAT quicklook plot.
The figure layout and quality are improved. In addition, several marking tools like vertical lines, shadings, top bars can be
added in the plot. See the example script and figure below:
In "example2.py"
```python
import datetime
import geospacelab.express.eiscat_dashboard as eiscat
dt_fr = datetime.datetime.strptime('20201209' + '1800', '%Y%m%d%H%M')
dt_to = datetime.datetime.strptime('20201210' + '0600', '%Y%m%d%H%M')
site = 'UHF'
antenna = 'UHF'
modulation = '60'
load_mode = 'AUTO'
dashboard = eiscat.EISCATDashboard(
dt_fr, dt_to, site=site, antenna=antenna, modulation=modulation, load_mode='AUTO'
)
dashboard.quicklook()
# dashboard.save_figure() # comment this if you need to run the following codes
# dashboard.show() # comment this if you need to run the following codes.
"""
As the dashboard class (EISCATDashboard) is a inheritance of the classes Datahub and TSDashboard.
The variables can be retrieved in the same ways as shown in Example 1.
"""
n_e = dashboard.assign_variable('n_e')
print(n_e.value)
print(n_e.error)
"""
Several marking tools (vertical lines, shadings, and top bars) can be added as the overlays
on the top of the quicklook plot.
"""
# add vertical line
dt_fr_2 = datetime.datetime.strptime('20201209' + '2030', "%Y%m%d%H%M")
dt_to_2 = datetime.datetime.strptime('20201210' + '0130', "%Y%m%d%H%M")
dashboard.add_vertical_line(dt_fr_2, bottom_extend=0, top_extend=0.02, label='Line 1', label_position='top')
# add shading
dashboard.add_shading(dt_fr_2, dt_to_2, bottom_extend=0, top_extend=0.02, label='Shading 1', label_position='top')
# add top bar
dt_fr_3 = datetime.datetime.strptime('20201210' + '0130', "%Y%m%d%H%M")
dt_to_3 = datetime.datetime.strptime('20201210' + '0430', "%Y%m%d%H%M")
dashboard.add_top_bar(dt_fr_3, dt_to_3, bottom=0., top=0.02, label='Top bar 1')
# save figure
dashboard.save_figure()
# show on screen
dashboard.show()
```
Output:

### Example 3: OMNI data and geomagnetic indices (WDC + GFZ):
In "example3.py"
```python
import datetime
import geospacelab.express.omni_dashboard as omni
dt_fr = datetime.datetime.strptime('20160314' + '0600', '%Y%m%d%H%M')
dt_to = datetime.datetime.strptime('20160320' + '0600', '%Y%m%d%H%M')
omni_type = 'OMNI2'
omni_res = '1min'
load_mode = 'AUTO'
dashboard = omni.OMNIDashboard(
dt_fr, dt_to, omni_type=omni_type, omni_res=omni_res, load_mode=load_mode
)
dashboard.quicklook()
# data can be retrieved in the same way as in Example 1:
dashboard.list_assigned_variables()
B_x_gsm = dashboard.get_variable('B_x_GSM', dataset_index=0)
# save figure
dashboard.save_figure()
# show on screen
dashboard.show()
```
Output:

The python distribution \"*__Anaconda__*\" is recommended:\nThe package was tested with the anaconda distribution and with **PYTHON>=3.7** under **Ubuntu 20.04** and **MacOS Big Sur**.\n\nWith Anaconda, it may be easier to install some required dependencies listed below, e.g., cartopy, using the _conda_ command.\nIt's also recommended installing the package and dependencies in a virtual environment with anaconda. \n\nAfter [installing the anaconda distribution](https://docs.anaconda.com/anaconda/install/index.html), a virtual environment can be created by the code below in the terminal:\n\n```shell\nconda create --name [YOUR_ENV_NAME] -c conda-forge python cython cartopy\n```\nThe package \"spyder\" is a widely-used python IDE. Other IDEs, like \"VS Code\" or \"Pycharm\" also work.\n\n> **_Note:_** The recommended IDE is Spyder. Sometimes, a *RuntimeError* can be raised \n> when the __aacgmv2__ package is called in **PyCharm** or **VS Code**. \n> If you meet this issue, try to compile the codes in **Spyder** several times. \n\nAfter creating the virtual environement, you need to activate the virtual environment:\n\n```shell\nconda activate [YOUR_ENV_NAME]\n```\nand then to install the package as shown below or to start the IDE **Spyder**.\n\nMore detailed information to set the anaconda environment can be found [here](https://conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#), \n\n### 2. Installation\n#### Quick install from the pre-built release (recommended):\n```shell\npip install geospacelab\n```\n\n#### Install from [Github](https://github.com/JouleCai/geospacelab) (not recommended):\n```shell\npip install git+https://github.com/JouleCai/geospacelab@master\n```\n\n### 2. Dependencies\nThe package dependencies need to be installed before or after the installation of the package. \nSeveral dependencies will be installed automatically with the package installation, \nincluding __toml__, __requests__, __bueatifulsoup4__, __numpy__, __scipy__, __matplotlib__, __h5py__, __netcdf4__,\n__cdflib__, __madrigalweb__, __sscws__, and __aacgmv2__.\n\nOther dependencies will be needed if you see a *__ImportError__* or *__ModuleNotFoundError__* \ndisplayed in the python console. Some frequently used modules and their installation methods are listed below:\n- [__cartopy__](https://scitools.org.uk/cartopy/docs/latest/installing.html): Map projection for geospatial data.\n - ```conda install -c conda-forge cartopy ``` \n- [__apexpy__ \\*](https://apexpy.readthedocs.io/en/latest/reference/Apex.html): Apex and Quasi-Dipole geomagnetic \ncoordinate system. \n - ```pip install apexpy ```\n- [__geopack__](https://github.com/tsssss/geopack): The geopack and Tsyganenko models in Python.\n - ```pip install geopack ```\n\n> ([\\*]()): The **_gcc_** or **_gfortran_** compilers are required before installing the package. \n> - gcc: ```conda install -c conda-forge gcc``` \n> - gfortran: ```conda install -c conda-forge gfortran ``` \n\nPlease install the packages above, if needed.\n\nNote: The package is currently pre-released. The installation methods may be changed in the future.\n\n\n### 4. First-time startup and basic configuration\nSome basic configurations will be made with the first-time import of the package. Following the messages prompted in the python console, the first configuration is to set the root directory for storing the data.\n\nWhen the modules to access the online Madrigal database is imported, it will ask for the inputs of user's full name, email, and affiliation.\n\nThe user's configuration can be found from the *__toml__* file below:\n```\n[your_home_directory]/.geospacelab/config.toml\n```\nThe user can set or change the preferences in the configuration file. For example, to change the root directory for storing the data, modify or add the lines in \"config.toml\":\n```toml\n[datahub]\ndata_root_dir = \"YOUR_ROOT_DIR\"\n```\nTo set the Madrigal cookies, change the lines:\n```toml\n[datahub.madrigal]\nuser_fullname = \"YOUR_NAME\"\nuser_email = \"YOU_EMAIL\"\nuser_affiliation = \"YOUR_AFFILIATION\"\n```\n\n### 5. Upgrade\n\nIf the package is installed from the pre-built release. Update the package via:\n```shell\npip install geospacelab --upgrade\n```\n\n### 6. Uninstallation\nUninstall the package via:\n```shell\npip uninstall geospacelab\n```\nIf you don't need the user's configuration, delete the file at **_[your_home_directory]/.geospacelab/config.toml_**\n\n## Usage\n### Example 1: Dock a sourced dataset and get variables:\nThe core of the data manager is the class Datahub. A Datahub instance will be used for docking a buit-in sourced dataset, or adding a temporary or user-defined dataset. \n\nThe \"dataset\" is a Dataset instance, which is used for loading and downloading \nthe data. \n\nBelow is an example to load the EISCAT data from the online service. The module will download EISCAT data automatically from \n[the EISCAT schedule page](https://portal.eiscat.se/schedule/) with the presetttings of loading mode \"AUTO\" and file type \"eiscat-hdf5\". \n\nExample 1:\n```python\nimport datetime\n\nfrom geospacelab.datahub import DataHub\n\n# settings\ndt_fr = datetime.datetime.strptime('20210309' + '0000', '%Y%m%d%H%M') # datetime from\ndt_to = datetime.datetime.strptime('20210309' + '2359', '%Y%m%d%H%M') # datetime to\ndatabase_name = 'madrigal' # built-in sourced database name \nfacility_name = 'eiscat' # facility name\n\nsite = 'UHF' # facility attributes required, check from the eiscat schedule page\nantenna = 'UHF'\nmodulation = 'ant'\n\n# create a datahub instance\ndh = DataHub(dt_fr, dt_to)\n# dock the first dataset (dataset index starts from 0)\nds_isr = dh.dock(datasource_contents=[database_name, 'isr', facility_name],\n site=site, antenna=antenna, modulation=modulation, data_file_type='eiscat-hdf5')\n# load data\nds_isr.load_data()\n# assign a variable from its own dataset to the datahub\nn_e = dh.assign_variable('n_e')\nT_i = dh.assign_variable('T_i')\n\n# get the variables which have been assigned in the datahub\nn_e = dh.get_variable('n_e')\nT_i = dh.get_variable('T_i')\n# if the variable is not assigned in the datahub, but exists in the its own dataset:\ncomp_O_p = dh.get_variable('comp_O_p', dataset=ds_isr) # O+ ratio\n# above line is equivalent to\ncomp_O_p = dh.datasets[0]['comp_O_p']\n\n# The variables, e.g., n_e and T_i, are the class Variable's instances, \n# which stores the variable values, errors, and many other attributes, e.g., name, label, unit, depends, ....\n# To get the value of the variable, use variable_isntance.value, e.g.,\nprint(n_e.value) # return the variable's value, type: numpy.ndarray, axis 0 is always along the time, check n_e.depends.items{}\nprint(n_e.error)\n\n```\n\n### Example 2: EISCAT quicklook plot\nThe EISCAT quicklook plot shows the GUISDAP analysed results in the same format as the online EISCAT quicklook plot.\nThe figure layout and quality are improved. In addition, several marking tools like vertical lines, shadings, top bars can be \nadded in the plot. See the example script and figure below:\n\nIn \"example2.py\"\n```python\nimport datetime\nimport geospacelab.express.eiscat_dashboard as eiscat\n\ndt_fr = datetime.datetime.strptime('20201209' + '1800', '%Y%m%d%H%M')\ndt_to = datetime.datetime.strptime('20201210' + '0600', '%Y%m%d%H%M')\n\nsite = 'UHF'\nantenna = 'UHF'\nmodulation = '60'\nload_mode = 'AUTO'\ndashboard = eiscat.EISCATDashboard(\n dt_fr, dt_to, site=site, antenna=antenna, modulation=modulation, load_mode='AUTO'\n)\ndashboard.quicklook()\n\n# dashboard.save_figure() # comment this if you need to run the following codes\n# dashboard.show() # comment this if you need to run the following codes.\n\n\"\"\"\nAs the dashboard class (EISCATDashboard) is a inheritance of the classes Datahub and TSDashboard.\nThe variables can be retrieved in the same ways as shown in Example 1. \n\"\"\"\nn_e = dashboard.assign_variable('n_e')\nprint(n_e.value)\nprint(n_e.error)\n\n\"\"\"\nSeveral marking tools (vertical lines, shadings, and top bars) can be added as the overlays \non the top of the quicklook plot.\n\"\"\"\n# add vertical line\ndt_fr_2 = datetime.datetime.strptime('20201209' + '2030', \"%Y%m%d%H%M\")\ndt_to_2 = datetime.datetime.strptime('20201210' + '0130', \"%Y%m%d%H%M\")\ndashboard.add_vertical_line(dt_fr_2, bottom_extend=0, top_extend=0.02, label='Line 1', label_position='top')\n# add shading\ndashboard.add_shading(dt_fr_2, dt_to_2, bottom_extend=0, top_extend=0.02, label='Shading 1', label_position='top')\n# add top bar\ndt_fr_3 = datetime.datetime.strptime('20201210' + '0130', \"%Y%m%d%H%M\")\ndt_to_3 = datetime.datetime.strptime('20201210' + '0430', \"%Y%m%d%H%M\")\ndashboard.add_top_bar(dt_fr_3, dt_to_3, bottom=0., top=0.02, label='Top bar 1')\n\n# save figure\ndashboard.save_figure()\n# show on screen\ndashboard.show()\n```\nOutput:\n> \n\n### Example 3: OMNI data and geomagnetic indices (WDC + GFZ):\n\nIn \"example3.py\"\n\n```python\nimport datetime\nimport geospacelab.express.omni_dashboard as omni\n\ndt_fr = datetime.datetime.strptime('20160314' + '0600', '%Y%m%d%H%M')\ndt_to = datetime.datetime.strptime('20160320' + '0600', '%Y%m%d%H%M')\n\nomni_type = 'OMNI2'\nomni_res = '1min'\nload_mode = 'AUTO'\ndashboard = omni.OMNIDashboard(\n dt_fr, dt_to, omni_type=omni_type, omni_res=omni_res, load_mode=load_mode\n)\ndashboard.quicklook()\n\n# data can be retrieved in the same way as in Example 1:\ndashboard.list_assigned_variables()\nB_x_gsm = dashboard.get_variable('B_x_GSM', dataset_index=0)\n# save figure\ndashboard.save_figure()\n# show on screen\ndashboard.show()\n```\nOutput:\n> \n\n### Example 4: Mapping geospatial data in the polar map.\n```python\nimport datetime\nimport matplotlib.pyplot as plt\n\nimport geospacelab.visualization.mpl.geomap.geodashboards as geomap\n\ndt_fr = datetime.datetime(2015, 9, 8, 8)\ndt_to = datetime.datetime(2015, 9, 8, 23, 59)\ntime1 = datetime.datetime(2015, 9, 8, 20, 21)\npole = 'N'\nsat_id = 'f16'\nband = 'LBHS'\n\n# Create a geodashboard object\ndashboard = geomap.GeoDashboard(dt_fr=dt_fr, dt_to=dt_to, figure_config={'figsize': (5, 5)})\n\n# If the orbit_id is specified, only one file will be downloaded.
