I have a netcdf file like this:

lat = 30x1

long = 15x1

sst = 30x15x1407

time = 1407x1

I need to write ASCII files for each lat-long (450 files) with [time sst] columns, where each file will be named as "sst_'lat'_lon'.txt". How can I create a loop to do that?

Working a little I reach to this:

varInfo = ncinfo('noaa-sst-1990-present.nc','sst');
disp(varInfo);
for latInd =1:varInfo.Size(1)
  for lonInd =1:varInfo.Size(2)
      fileName = ['sst_',num2str(latInd),'_',num2str(lonInd),'.txt'];
      tSeries  = [ncread('noaa-sst-1990-present.nc','sst',[latInd, lonInd, 1],[1,1,varInfo.Size(3)])];
      dlmwrite(fileName,squeeze(tSeries),'delimiter','\t','precision',5);
  end
end

But I could only write the sst columns, but I want to save [time sst]. I tried to manipulate tSeries to include time column, but didn't get it.

How can I get that?

It can be done...But my question is why you want to do it? You have all the data happily in netcdf, ascii will occupy much space and lot of files. Why?
