 General Methods:
 Original temperature values are corrected for the difference in
 topography between NCEP 2.5x2.5 deg elevation and DEM-based
 25x25 km elevation on EASE grid. The atmospheric lapse rate is calculated
 from NCEP higher pressure level data with the condition that the used level
 has to be at least 750m above the height of the (old) surface value.
 A correction is made for topography differences of up to 500m
 (above which - some high mountain peaks - 500m is taken as the
 maximal difference.
 A constant height of 40m for the (old) sigma 0.995 temperatures is
 assumed. The final topography-corrected values also take into
 account these 40m and would be 'real' surface temperatures.
 Minimum and maximum daily temperatures are set to -60 C and +35 C,
 respectively.
