Message en plusieurs parties au format MIME --=_alternative 00552D7B41256E36_ Content-Type: text/plain; charset="us-ascii" Hi all, I'm a beginner with NetCDF and NCO. I have several files 1990.nc, 1991.nc ..., each of them containing annual data jan, feb, ..., dec. I want to calculate the climatology, but using ncea gives me a file with something that is not the arithmetic mean of the individual files. After some inquiries, I think this is due to the fact that each input file (variable type is short) as a different add_offset and scale_factor. Using ncea seems to attribute to the ouput file the add_offset and scale_factor of the first input file. Does anybody know how I can proceed to get the correct climatology ? Is it possible with ncap ? How should I use it ? Thank you very much for any help ! All the best Laurent --=_alternative 00552D7B41256E36_
