Developer’s Guide Components:

1.6. Prerequisites

These polar2grid topics should be understood to get the most out of this guide:

  • The general design of Polar2Grid

  • The responsibilities of a reader

  • The responsibilities of a writer

  • Package hierarchy and dependencies

A developer should be familiar with these concepts to develop a new component for polar2grid:

  • python and numpy programming

  • remapping/regridding satellite imagery swaths (including types of projections)

  • python packaging, specifically distribute (setuptools)

  • git source code management system and the ‘forking’ and ‘pull request’ features of http://github.com

  • Xarray and dask programming and how it is used by the Satpy library
