I'm not completely familiar with ncdf_varget but short is probably
referring to a short integer not a floating point number. This just
means its a 2 byte integer (i.e. data type 2 in IDL speak). It is
common for data of this type to be stored in this way in scientific
data formats.

I'm not sure what you're issue is. It appears from above it is being
read in correctly. When you multiply data * scalef it will become a
floating point array and give you the correct result.
