Data from HiRLAM

The High-Resolution Limited Area Model HiRLAM is an atmospheric model operated by KNMI (and other met offices). Like all atmospheric models HiRLAM is a numerical approximation of the physical description of the state of the atmosphere in the near future. The daily runs are initiated at 0, 6, 12 and 18 h Universal Time, starting with initial conditions originating from recent measurements. The output consists of the expected average value of physical quantities like wind speed at various vertical levels up to 30 km above mean sea level in a horizontal grid, to date with a size of 0.2x0.2 deg2, covering Europe and vicinity and with a time step of 1 or 3 hour up to 48 hours after initiation.

The hierarchy of the consecutive runs is as follows: 

ECN obtains the HiRLAM data from KNMI under agreement 2001/265 for the daily delivery of meteorological data, and has been maintaining a database with HiRLAM data files since June 2001.
