Regional   Atmospheric   Soaring   Prediction
Boundary Layer Information Prediction MAP
The Netherlands, North Belgium and Northwest Germany

The atmospheric Boundary Layer (BL) is the vertical region above the surface within which air has been mixed by thermal or windshear eddies, i.e. the region where gliders, hanggliders and paragliders normally fly. The RASP BLIPMAP model is developed by Dr. John W. (Jack) Glendening and is a WRF model specifically adapted for these gliders. The basic parameters are described here and all parameters here. A description of all parameters in German can be found here. If you have any remarks or questions, please email rasp@blipmaps.nl.
The results are available for today at 08:30 local time, for tomorrow at 09:30 and for the day after tomorrow at 10:30 at the latest and depending on the weather sometimes up till 30 minutes earlier. Animations have only been made for those parameters of which the legenda doesn't change througout the day. After midnight all results are copied to one day earlier. Due to this until 10:30 no results are available for the day after tomorrow. How actual the forecast is can be derived from the number of hours that is noted in each picture before the text "hrFcst@". This is the difference between the model starttime and the time at which the forecast is valid. If you have difficulties distinguishing colors then thishelps.
