The BOLAM model graphical outputs are daily available as the result of a cooperation between the Institute of Atmospheric Sciences and Climate in Bologna (ISAC-CNR), the Physics Department of the University of Genoa (DIFI) and the Meteo-Hydrological Centre of the Liguria Region (ARPAL-CMIRL).

Two different runs are performed since the beginning of the Special Observing Period of the Mesoscale Alpine Programme (September 1999, MAP SOP ):

21 km resolution:

    • initial and boundary conditions: derived every 6 hours from ECMWF (initialized at 00 UTC, rotated grid, obtained through Aeronautica Militare) hybrid levels;
    • duration: 72 hours (from 00 to 72 UTC);
    • grid: rotated horizontal Arakawa C-grid; 154´144 grid points at the resolution of 0.20 degrees; 30 vertical levels;

6,5 km resolution:

    • initial and boundary conditions: self nested (every 90 minutes) in the 21 km run;
    • duration: 36 hours (from 12 to 48 UTC);
    • grid: rotated horizontal Arakawa C-grid; 140´130 grid points at the resolution of 0.06 degrees; 40 vertical levels;
