The dataset is covering:
- the period from 1 August 2018 until present for 2-days delayed test data (experiment 9701)
- the period from 29 October 2018 until present for near real-time test data (experiment 9704)
- the period from 1 December 2018 until present for near real-time production data with a land-sea mask applied (experiment 0010)
MARS
If you have access to ECMWF systems you can retrieve test data from MARS archive using keywords:
class=mc expver=9710 stream=gfas type=ga
Or the definitive production data, using keywords:
class=mc expver=0010 stream=gfas type=ga
FTP dissemination
The near real-time test data (9704) is already available through ECPDS FTP dissemination systems in this directory:
/DATA/CAMS_GFAS_HOURLY/
You can use your normal FTP account to access the data.
On the XX January 2019, we will stop pushing test data (9704) to the ECPDS FTP dissemination directory and start to push the production data (0010) to the same directory. This change will be almost transparent for users. The only noticeable differences will be:
- Sea points in all data field will have value 0, as a land-sea mask will be applied to them.
- Users retrieving grib files will notice that attribute "experiment Version Number" will be 0010 instead of 9704:
$ grib_ls -p experimentVersionNumber z_cams_c_ecmf_201901100400_gfas_an_sfc_024_frpfire.grib z_cams_c_ecmf_201901100400_gfas_an_sfc_024_frpfire.grib experimentVersionNumber 9704 1 of 1 messages in z_cams_c_ecmf_201901100400_gfas_an_sfc_024_frpfire.grib
