[gradsusr] How to convert grib to netcdf or read grib files in GrADS

[dolesibeni]

Dear All,
I am new to grib1 and grib2 data,  I downloaded these data sets from ECMWF site and the data is .grib and grb2 formart. I would like to work this data for a case study of extreme rainfall event and flooding that took place in my country.
I downloaded this data becuase i wanted a high resolution data set and i was unable to get this thro7gh groogling. The data set contains, u and v components,precipitation totals, temperatures etc.
Could anyone help how i can read this data using grads or hown i can convert it to netcdf format which i am familiar with. I tried to do the following:
In windows  >cdo -f nc copy grip file outputfile.nc
 And i am getting an error 
Please help

you could cat all your files into a single one and avoiding template
or splitting each of them into 12 (months) files. Using this second
chance you could use template sal.%y4%m2.grb

hoping it helps ...

bye bye
