### This archive contains git repositories for the operational science data processing code used by the NASA PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) CubeSat mission to create the public R01 release of the science data products.

The PREFIRE observational science data archive is archived by the NASA Atmospheric Science Data Center (https://asdc.larc.nasa.gov/), and can be accessed via the data set landing page (https://asdc.larc.nasa.gov/project/PREFIRE) and NASA Earthdata Search (https://search.earthdata.nasa.gov/search?fpj=PREFIRE).

It may also be useful to refer to the PREFIRE data product User Guides (https://prefire.ssec.wisc.edu/Documents/User_Guide/index.html) and ATBDs (https://prefire.ssec.wisc.edu/Documents/ATBD/index.html) (Algorithm Theoretical Basis Documents).

Each PREFIRE git repository contains an annotated 'R01' tag that indicates which git commit corresponds with the operational code used to produce those science data products.  The README files in each git repository contain further invaluable information about additional code and/or data dependencies.
