Description

Create a raster of flux footprint data. Specific to expanded package of eddy covariance data product: DP4.00200.001 For definition of a footprint, see Glossary of Meteorology: https://glossary.ametsoc.org/wiki/Footprint For background information about flux footprints and considerations around the time scale of footprint calculations, see Amiro 1998: https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.922.4124&rep=rep1&type=pdf
