Opening netcdf in matlab has become much straightforward:

Read the information:

information = ncinfo('filename.nc');

variable = ncread('filename.nc', 'Var');

Cheers!

Thank you very much ! Are there simple routines to open grib1 and grib2 files in MATLAB?

George It is simple to read netcdf files and get info using MatLab but this is more simple using ncdump command.

Dear George

Below I have some code which could be the starting point of extracting NC data into Matlab. Grip files I suggest converting to NC in CDO before fetching them into Matlab.

Regards

Morten

ncname1='Data.nc'; % insert correct name

%Display the metadata for the file (go though to familiarize with the format)

ncdisp(ncname1);

%Get file information (and show dimension names and variable names)

finfo=ncinfo(ncname1);

dimNames = {finfo.Dimensions.Name};

varNames = {finfo.Variables.Name};

disp(dimNames);

disp(varNames);

%Load the variables

dlon = ncread(ncname1,'longitude');

dlat = ncread(ncname1,'latitude');

dtime = ncread(ncname1,'time');

variable = ncread(ncname1,'variable_name');

etc...

This is quite an old thread but one can download the nctoolbox and store it in the startup file.  You will need to use terminal to find the startup file.  nctoolbox has something called nc.geodataset('data') to read it in.  It is slow as hell though.
