Forecasts

We develop proprietary weather models and use them to run our own forecasting system, called the Experimental Forecast System (EFS). It is currently in the process of being built. EFS uses two models:

• GAME for global forecasts
• L-GAME for regional forecasts over Germany with 23 km resolution.

You can find EFS output here:

• Maps
• Point forecasts
• Direct model output (DMO)

Note: The data might be unavailable or suddenly change. Disclaimer.

Overview of GAME runs

Analysis (UTC)	Run finish (UTC)	Resolution / km	Run length / days
0:00	2:10	112	7
6:00	8:10	112	7
12:00	14:10	112	7
18:00	20:10	112	7

Overview of L-GAME runs

Analysis (UTC)	Run finish (UTC)	Resolution / km	Run length / days
3:00	4:00	23	3
9:00	10:00	23	3
15:00	16:00	23	3
21:00	22:00	23	3

Initialization and boundary conditions

For initialization, a suite of tools named real2GAME is used. The sources of the data assimilation are

• METARs,
• SYNOP reports,
• and ship reports.

The boundary conditions of L-GAME are generated by interpolating the GAME forecast to the L-GAME grid.
