    Thank you for this detailed video on how to read a netcdf file. I'm using GSMaP precipitation data which is in .dat file format can you make a video on how to convert such files into netcdf file. Thank you!

      Thanks. You might find my video on creating a netcdf file useful. You can find it in the same playlist and in the description to this video.

    Amazing video. Thank you!
    How do I fix this problem: AttributeError: partially initialized module 'xarray' has no attribute 'open_dataset' (most likely due to a circular import)?

      You can fix the `AttributeError` by following these steps:
      1. **Check for Circular Imports**: Ensure there are no circular dependencies in your imports.
      2. **Correct Import Statement**:
      ```python
      import xarray as xr
      dataset = xr.open_dataset('your_dataset_file.nc')
      ```
      3. **Avoid Module Name Conflicts**: Ensure your script is not named `xarray.py` or similar.
      4. **Verify Environment**: Make sure you are using the environment where xarray is installed.

    Hi Luke, how are you dude? Excuse me, I'm trying to see a .nc from Modis Aqua satellite for to get the chlorophyll concentration with Python, I'm follow your steps but the file doesn't show the variables, it's empty. Do you have some video about this situation?

      Very unusual. Where can I find the data?

      ​@@LukeDataManager You can download from ocean color web site, is a NASA page, this is the link where you can get a .nc file : oceancolor.gsfc.nasa.gov/cgi/browse.pl?sen=amod
      or if you want a can send you a email with the file attached

    Thanks for the video. But how to read separate nc file in the computer?

    • @LukeDataManager

      Do you mean if you have multiple files on your computer? Then you need to open them one by one in a for loop for example.
      You might find this video useful: ua-cam.com/video/AbLRV5YUW2g/v-deo.html
      In it I extract data from multiple NetCDF files that are hosted on a THREDDS server. But you can adapt the code to loop through files on your computer instead of a THREDDS server.
      Just use the relative or absolute filepath to your netcdf files instead of the OPeNDAP URL.
