how to read a time series data at a particular (x, y) grid cell in a netcdf file

Dear all,

The netcdf file was composited a dimension of x = 570 and y = 480.

How to extract a time series data at a particular grid cell in Matlab?

I've tried the nctoolbox, however the results are not identical with that in ncview. (ps. I guess the nctoolbox regard the (x, y) is the real longitude and latitude!?) So, I need to find the other solutions. Please see the attached the file at http://db.tt/WIqIt2u1

Please help me on this.

Thanks a lot.

Michael

Look at ncread (and ncdisp) if your version of MATLAB had it.

% time series of lon 120, lat 250
tpix = squeeze(ncread('/tmp/wetd.mon.nc','wetd',[120, 250, 1, 1], [1,1,1,12]))

tpix =

     10.8050
      8.4050
      8.9470
      6.0860
      9.6200
     11.8550
     13.4120
     11.5200
     10.4780
      7.6780
     10.1200
      9.4700

hi,

I wanted to extract data using a netCDF file for a selected lat and long coordinate but this code did not work. Please see the attached file.

Any help is appreciated.

Thanks.
