[gradsusr] How to combine the different nc files to calculate the mean and SD? Thanks.

Tue Jan 8 00:47:00 EST 2013

In my case. I have zlib, szip and szip enabled hdf5 already installed in my
desktop so I have installed with hdf5. I am not much technically sound, but
we may need hdf5.

I explain what i have done during that time.

step-1: Install zlib
step-2: install szip
step-3: install hdf5 with szip
step-4: install netcdf with hdf5
step-5: install CDO with netcdf, hdf5, szip, zlib

I did not use grib_api and jasper ....

I don't know much about the technicality but, it worked for me...

Regards,

Kishore
