Africa - 12 km Resolution

Each tile covers an area of 120 km x 120 km (10 x 10 12-km grid points). It includes hourly data for a full year. The time stamp of the data is UTC (GMT) time. Each tile contains 8760 hours (or 8784 hours for a leap year) plus 12 hours of the prior year (in UTC time) and 12 hours of the following year (in UTC time).

The hourly 3-D meteorological parameters included in the tiles are wind speed, wind direction, temperature, pressure, Geopotential height, vertical velocity, relative humidity, mixing ratios for water vapor, cloud water, rain, ice, snow, graupel. Hourly surface (2-D) parameters in the tiles include sea-level pressure, rainfall amount, snow cover, short wave and long wave radiation at the surface, air temperature at 2m, specific humidity at 2m, wind speed and wind direction at 10m and sea surface temperature. There are 52,000 3-D data points per hour and 1,000 2-D data points per hour included in each tile. Each tile contains one year of data in a packed (compressed) format that is roughly 450 MB in size

CALMET contains algorithms to compute the cloud cover and ceiling height for each CALMET grid point from the relative humidity and liquid water data contained in the MM5 dataset.
