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.

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.

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.
