Hi,

I attempt to abtain the mass stream funtion using function mastrfu and my procedure is as follows

step1.

cdo zonmean vwnd.mon.mean.nc zonmean.nc

step 2.

cdo mastrfu  zonmean.nc   msf.nc

some warnings occurred:

cdo mastrfu (Warning): Unexpected code -1!
cdo mastrfu (Warning): Some data values (min=-2.14748e+09 max=-2.14748e+09) are outside the
valid range (-32768 - 32767) of the used output precision!
Use the CDO option -b 32 or -b 64 to increase the output precision.
cdf_put_vara_double : ncid = 4 varid = 4 val0 = -3847409.000000

Error (cdf_put_vara_double) : Numeric conversion not representable

Could you give me some advice to solve this problem?

Thanks in advance
