Parametrizations	Coarse mesh	Fine mesh
Surface scheme	Five-layer soil model	Five-layer soil model
Covective precipitation	Grell	Kain-Fritsch 2
Grid scale precipitation	Simple ice (Dudhia)	Schultz
Planetary boundary layer	MRF	MRF

Output files were interpolated to regular latitude longitude grid (0.8 degree for coarse mesh and 0.2 degree for fine mesh) and have the following variables:
1. Sea level pressure (mb)
2. 3-hour accumulated total (convective + grid scale) precipitation (mm)
3. geopoetential height (m)
4. zonal wind (m s-1)
5.meridional wind (m s-1)
6. air temperature (oC)
7. mixing ration (kg/kg)
8. vertical velocity (m s-1)
 
These output files are in binary format and are:
