I just started practicing GrADS tutorial. and I'm stuck at the first page which was about 'gridded data' and 'station data'

What is the difference between gridded data and station data? Furthermore, when do we use gridded or station data?

Station data contains observations at different "stations." That could be readings from ASOS or other platforms. Gridded data is more like model output. You have a grid on which the numerical model is ran, with this you have a data value at every grid point, both horizontally and vertically.

As for usage, it depends what you are trying to visualize/analyze.

Let me know if you have other questions, I have a lot of experience with GrADS and atmospheric science gridded data.
