Polar2Grid is a set of command line tools for extracting data from earth-observing satellite instrument files, remapping it to uniform grids if needed, and writing that gridded data to a new file format. It provides an easy way to create high quality projected images. Polar2Grid was created by scientists and software developers at the SSEC. It is distributed as part of the CSPP LEO project for processing of data received via direct broadcast antennas. Although Polar2Grid was created to serve the direct broadcast community, it can be used on most archived data files.

The features provided by Polar2Grid are accessible via bash scripts and binary command line tools. This is meant to give scientists an easy way to use and access features that typically involve complicated programming interfaces. Linux terminal commands included in these instructions assume the bash shell is used.


A collaboration between the Polar2Grid and PyTroll team will change a majority of the low-level code in future versions of Polar2Grid. However, the bash scripts will still be available to provide the same functionality with which users are familiar. Polar2Grid terminology such as “frontend” and “backend” is now used interchangeably with the SatPy terminology “reader” and “writer”.
