I have a nc file with 145 long, 129 lat and 10227 time values, I want to change this daily data (10,227) to monthly values. What could be easy way?

Actually, this is a climate data and I need monthly values from which I shall create seasons and plot in map form.
Hi Neha Kanda
this is John BG <mailto:email@example.com firstname.lastname@example.org>
why more longitudes than latitudes: are there missing latitudes, or same longitude repeats along diverse longitudes?
Same for time stamps, please confirm that you have many void time stamps, without coordinates I mean.
Any chance for you to attach a sample of the data described in your question?
appreciating time and attention, awaiting answer
so far, without a sample of the data to process, I have the impression that your question gets solved by translating the netcdf file to a MATLAB structure.
Once the data in a MATLAB structure, it's straight forward to get the data you want.
Please have a look at Lazerson's function read_netcdf
If you attach a sample of the data to your question I will use that function or other available in the MAthworks file exchange related to NetCDF to then obtain MATLAB format data to work with.

You should be having dates in your hand.......read the dates....pick the months and calculate the mean of monthly data.

It is not a deal..it can be done...you need to get indices of months you want and run mean on the roster...the output would be a raster itself...it can be then written to NC file..

This seems like it could be easily solved using retime on a timetable, but there's not enough information in you post to go on.
