Description
The L2B snow grain size PGE takes as input L2A corrected surface reflectance and calculates snow grain size using the method of Nolin and Dozier (2000). Snow grain size is modeled as a function of scaled band area centered at the 1030 nm ice absorption feature. Snow grain size should only be calculated for pixels with greater than 90% snow cover. Output includes snow grain size esimates (micrometers) and a quality assurance mask that flags pixels with grain size estimates outside of the range of the model (60 - 1000 microns). Output format is a 2-band GeoTIFF with metadata in JSON format. This repository holds an archive of the source code (sister*.tar.gz) with full Common Workflow Language (CWL) per the Open Geospatial Consortium (OGC) Best practice document (https://docs.ogc.org/bp/20-089r1.html): a docker container (ogc*.tar.gz) and a process file (*.cwl).
