Models and acronyms:

ECMWF (European Centre for Medium-Range Weather Forecasts)

Models are called EC.

Determinist model : one forecast (one trajectory) every 6h (00h, 06h, 12h and 18h) called EC OP
- 00h and 12h run have 240h of forecast (~9 days)
- 06h and 18h run have 90h of forecast (~3 days)
Ensemble model : several forecasts (50 different trajectories) every 6h (00h, 06h, 12h and 18h) called EC ENS
- 00h and 12h run have 360h of forecast (~14 days)
- 06h and 18h run have 90h of forecast (~3 days)
Extended ensemble model : several forecasts (100 different trajectories) every day called EC ENS EXTENDED
- Forecast up to 46 days

NOAA (National Oceanic and Atmospheric Administration)

Models are called GFS.

Determinist model : one forecast (one trajectory) every 6h (00h, 06h, 12h and 18h) called GFS OP
- Forecast up to 15 days
Ensemble model : several forecasts (30 different trajectories) every 6h (00h, 06h, 12h and 18h) called GFS ENS
- Forecast up to 15 days

Historical data

Actuals data are what is the closest to observations. To produce them we take the last forecasted values for each target hour. For example we take the first 12 hours of run 00h and first 12 hours of run 12h to have an entire day of actuals.

EC OP: We have data up to 2015-01-01 on European grid ("EU": "71/-15/35/45") with information every hour and a resolution of 0.1°.
GFS OP: We have data up to 2015-01-15 on European grid ("EU": "71/-15/35/45") with information every 3 hour and a resolution of 0.25°.

Classic parameters

There are 2 types of parameters : cumulated and instantaneous.

Instantaneous parameters: 2t, 2d, 100u, 100v, 10u, 10v, sp. This means that the hour indicated matches the exact time at which the parameter is calculated.

Cumulative parameters: tp, ssrd, ssr. Here, this means that the parameter is the accumulation since the beginning of the run (ECMWF) since the last modulo 6h (NOAA).
