NCEP data is available from 1961-2005. However I only want to use NCEP from 1975-2005 in SDSM. How can I extract from the given NCEP data for the specific period of 1975-2005?
downlod .nc files of your variables and just read them in matlab to extract files of your years.
Reading nc file is very easy in MATLAB. Use ncdisp('air.mon.mean.nc') to view the contents of the file. ncdisp shows you variables, dimensions of the file. After looking into variables, you can read what ever the variable you want. To read longitude and latitude: lon = ncread('air.mon.mean.nc','Lon') ; % Lon is variable as given above lat = ncread('air.mon.mean.nc','Lat') ; % LAt is variable as given above
Another option is to use OpenDap option which give you text files. Check it!
