A rolling MARS archive containing the ENS BC data has been put in place. This dataset has the following characteristics:
- The data are kept for 30 days.
- The data are stored online in the Fields Database (FDB) on the HPC systems.
- 5.75 days of forecast data are kept: hourly until step 90, then three hourly until step 138.
- Data for th4 4 daily runs (at 00, 06, 12 and 18 UTC) are stored
- The Control and 50 Perturbed Forecasts are available only, as well Surface and Model level data
- The usual access restrictions to real time forecast data are applicable to these ENS BC data.
Parameters available:
- Model Level PF data: like archived for the CF
- Surface Data: like in the archive
