Could anybody please explain me my mistake if possible.

I created the following ddf based on the OUT_HEAD.CTL I have.

THere is a mistake somewhere however since my attemts to draw

say precipitation give me seemingly correct distribution of rain but the values

are of order of -32700.

At the same time my precipitation is very reasonable if I open

the *.nc file (see ncdump below) using sdfopen.
