# ecquote
A package to estimate the cost and volume of an ECMWF dissemination feed based on the rules described [there](https://www.ecmwf.int/en/forecasts/accessing-forecasts/payment-rules-and-options/tariffs).
To use the tool, edit a file that contains the
a series of [MARS requests](https://confluence.ecmwf.int/display/UDOC/MARS+command+and+request+syntax) as follows:
class=od,
stream=oper,
expver=0001,
levtype=pl,
type=an,
time=0000/1200,
param=z/t/u/v,
levelist=500/850,
grid=0.1/0.1,
area=40/0/30/50
type=fc,
step=0/to/240/by/24
type=cf,
stream=enfo
type=pf,
number=1/to/50
The verb of the request, such as `retrieve` or `dissemination`, is optional. The example above describes four requests. As for with the MARS language, attributes that are not specified are inherited from the previous request.
Then simply run the `ecquote` tools:
ecquote myrequests.req
You then should get a result such as:
Grand total:
Yearly volume: 256.9 GiB
Yearly fields: 3,346,320
Volume band: 1 GiB
Volume cost: EUR 200
EPUs: 16,627
Discounted EPUs: 10,776
Information cost: EUR 5,388 (core: 5,388)
To get a description of how the cost is determined, rerun the command with the option `--detailed`.
