Hi,

I have multiple folders from 1998 to 2012 in each folder there are 365 .nc files. File names in each folder appear like this 3B42_daily.1998.01.01.7.SUB.nc except for the year in different folders. How can I merge 365 files in each folder to one .nc file.

Then from each merged file, I need to extract variable r for 378 lat, lon locations?

I have the following code to read from each file but it does not merge.

myVarName = 'r';
for yr=1998:2012
  inFile  = strcat('cantho_trmm_daily_',num2str(yr),'.nc'); 
  nc=netcdf.open(inFile,'NC_NOWRITE');
  netcdf.close(nc)
end
 inVar1 = ncread(inFile,myVarName);

Can somebody help me to figure this out?

Thanks in advance.

As far as Im aware theres no such function to merge ncdf files in matlab but you can use raster package in R which has stack() function to make a raster stack from separate netcdf files. see this link https://rpubs.com/markpayne/358146
