I am a computer science student and want to build some machine learning application for precipitation rate estimation using machine learning. For proof of concept I decided to predict precipitation rate at one particular location. I am using pyart to get the data from the radar for the lat/lon of the location. However, I am unable to get the data from around the particular lat/lon.

I am wondering if there is a way to get like a 5x5 km radius of data around the given lat/lon coordinate?

For extracting radar data around a specific lat/lon, you might want to check out these Python libraries:

- [Py-ART](https://arm-doe.github.io/pyart/)
- [xradar](https://docs.openradarscience.org/projects/xradar/en/stable/)
- [wradlib](https://wradlib.org/)

Each library includes examples that can help you get started. If you need further assistance, feel free to connect with the open radar science community [here](https://openradar.discourse.group/)

Thank you @aladinor, I am currently using Py-ART for extraction

```auto
pyart.util.columnsect.get_field_location(data, lat, lon)

```

Thank you for sharing the Open radar science community link.
