    Hi, Thank you so much for your explanation, it is very useful! Do you have any clue about how to reproject NetCDF rasters, and more specifically, how to pass from rotated coordinates to regular ones, as long as many climate datasets have a rotated CRS? I'm not finding anything resolutive!

    Thanks for the video. How can we clip a netCDF dataset by a shapefile and get the spatially averaged value of the variable??

      Hi, I would suggest you export it as a raster to a format like tiff, and then use tools such as spatial statistics/ zonal statistics to get the average of the pixel values within the boundary demarcated by a shapefile

      @@geodeltalabs I cliped the netCDF dataset by bshapefile.. But the issue is that the dataset change to other format... I just need the netcdf format only having the temporal layers. Can you please help.. I also try multidimentional data management tool in ArcGIS pro.. The problem is that the tool can mask by extend only but not by polygon. It will be great help if you suggest something positive.

    Thanks. This is extremely useful. I was wondering if you have a guide to writing a python script so that we can create a separate raster for each of the months? My nc file has 480 months. Point and click would be too consuming.

      Great suggestion! however i do not have a script written for such kind of case. However, if you follow the netcdf tutorial series that I have done, you might be able to get an insight on how to formulate a simple script to do such a iterative task :) all the best

    Hi, thank you very much for your video! I was wondering, do you know the workaround of calculating the average value for the sum of these "bands" which i have in netCDF file, not exporting rasters one-by-one. Thank you!

      you should use matlab then. I had to do the same! to read an NC file you can use ncread.
      Example : temperature = ncread(file_address, 'temperature');

    Hii ! I have a problem converting my file into a raster because the choices in X and Y dimensions are only time and level. How to fix this problem?

      Hi, you can follow my netcdf video series. I have explained how to use python to extract data such as temp, precipitation etc.
