Python AWIPS Data Access Framework

The python-awips package provides a data access framework for requesting grid and geometry datasets from an EDEX server.

AWIPS is a weather display and analysis package developed by the National Weather Service for operational forecasting. UCAR’s Unidata Program Center supports a non-operational open-source release of the AWIPS software (EDEX, CAVE, and python-awips).

Pip Install

pip install python-awips
