This data set consists of surface radiative and turbulent fluxes, cloud properties as well as meteorological variables such as temperature and moisture profiles for the period 1987 - 1997 over the Antarctic on a 200 km grid. All parameters are expressed as monthly averages.

The data set was derived by incorporating cloud properties from the extended AVHRR (Advanced Very High Resolution Radiometer) Polar Pathfinder Data set (APP-x) into the Arctic Region Climate System Model (ARCSyM) in order to improve the simulation of the Antarctic surface energy balance.

The following monthly mean parameters are available:

Surface Energy Budget and Clouds:	Other Parameters:
Downwelling longwave flux at the surface Upwelling longwave flux at the surface Net shortwave flux at the surface Sensible heat flux at the surface Latent heat flux at the surface Net radiative flux + turbulent heat flux at the surface Cloud optical depth Cloud fractional cover Total cloud cover Cloud liquid water content	Zonal wind velocity Meridional wind velocity Atmospheric temperature Atmospheric moisture Surface pressure Ground temperature Two meter temperature Sea ice thickness Sea ice concentration

The ARCSyM 200 km horizontal grid used to produce the data set is shown in the figure below.

Here are a few examples of the data set:

• Sensible heat flux at the surface (January, 1987)
• Latent heat flux at the surface (January, 1987)
• Downwelling longwave flux at the surface (January, 1987)
• Upwelling longwave flux at the surface (January, 1987)
• Net shortwave flux at the surface (January, 1987)
• Total cloud amount (January, 1987)
