If you don't have access to ECMWF computers but would still like to access a large subset of test data you can use ECMWF WebAPI service.

Info

Read documentation and see brief request syntax of the ECMWF WebAPI service.

If you haven't done it yet you will need to create an ECMWF web account and accept the data licence.

Examples

Total aerosol optical depth at 550 nm in NetCDF format, only European domain, 10 dates, day 1 forecast

Code Block
languagepy
titleGRIBNetCDF
#!/usr/bin/env python
from ecmwfapi import ECMWFDataServer
server = ECMWFDataServer()

server.retrieve({
    "dataset":   "cams_esuite",
    "stream":    "oper",

    "levtype":   "sfc",
    "format":    "netcdf",
    "param" :    "aod550",         # see parameter table at http://atmosphere.copernicus.eu/ftp-access-global-data
    "grid":      "0.4/0.4",        # 0.4 x 0.4 regular lat-lon grid
    "area":      "70/-35/35/60",   # N/E/S/W area boundaries
    "target":    "/tmp/cams_test_201706201707.nc"
})

 

FTP dissemination

The test dataset is available through ECPDS FTP dissemination systems in these directories:

Code Block
/DATA/CAMS_NREALTIMEGLOBAL_TEST
/DATA/CAMS_NREALTIMEEUROPE_BC_TEST

You can use your normal FTP account to access the data. The list of parameters is the same as in the current data streams.
