Extract eddy covariance footprint data from HDF5 format

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

Usage

footRaster(filepath)

Arguments

filepath

One of: a folder containing NEON EC H5 files, a zip file of DP4.00200.001 data downloaded from the NEON data portal, a folder of DP4.00200.001 data downloaded by the neonUtilities::zipsByProduct() function, or a single NEON EC H5 file. Filepath can only contain files for a single site. [character]

Details

Given a filepath containing H5 files of expanded package DP4.00200.001 data, extracts flux footprint data and creates a raster.

Value

A rasterStack object containing all the footprints in the input files, plus one layer (the first in the stack) containing the mean footprint.
