Hi,
I understand that you want to combine multiple NetCDF files into a single NetCDF file. You can achieve this by following these steps:
- Use ‘nccreate’ to create an output file.
- Use ‘ncread’ to read data from each of the input files.
- Cumulatively write the data into the output file using ‘ncwrite’.
Here is the code implementation of the above steps:
% The code creates 3 NetCDF Files and combine them.
numFiles = 3;
dimSize = 10;
% Step 1: Create Multiple NetCDF Files
for i = 1:numFiles
filename = sprintf('test_file_%d.nc', i);
nccreate(filename, 'data', 'Dimensions', {'x', dimSize, 'y', dimSize})
data = rand(dimSize, dimSize);
ncwrite(filename, 'data', data);
end
% Step 2: Combine NetCDF Files into One
outputFile = 'combined_file.nc';
% 'data' is the variable name in the NetCDF file
nccreate(outputFile, 'data', 'Dimensions', {'x', dimSize, 'y', dimSize, 'file', numFiles});
for i = 1:numFiles
filename = sprintf('test_file_%d.nc', i);
data = ncread(filename, 'data');
ncwrite(outputFile, 'data', data, [1, 1, i]);
end
You can refer to the documentations for the functions used:

- ncread: https://www.mathworks.com/help/matlab/ref/ncread.html
- ncwrite: https://www.mathworks.com/help/matlab/ref/ncwrite.html
Hope this helps!
