• the average elevation above mean sea level (MSL),. This is taken from the smoothed model orography.
• the fraction of land. This is used to assess the proportions of each grid square used by HTESSEL and FLake to derive heat, moisture and momentum fluxes. 
• the fractional cover of different vegetation types.   This is used by HTESSEL to derive the different proportions of heat, moisture and momentum fluxes over the land.

This detailed data is upscaled (aggregated) to the coarser model resolution.
