VIIRS/JPSS2 Gross and Net Primary Production Gap-Filled Yearly L4 Global 500m SIN Grid V002
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/viirs/vj217a3gf.002
Description
The NOAA-21 Visible Infrared Imaging Radiometer Suite (VIIRS) Gross and Net Primary Production (NPP) Gap-Filled (VJ217A3GF) Version 2 data product is a cumulative composite of Gross Primary Productivity (GPP) values based on the radiation-use efficiency concept that is potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation. VJ217A3GF is a yearly composite at 500 meter spatial resolution delivered as a gridded Level 4 (L4) product in Sinusoidal projection.
The VJ217A3GF will be generated at the end of each year when the entire yearly 8-day VJ215A2H is available. Hence, the gap-filled VJ217A3GF is the improved VJ217A2, which has cleaned the poor-quality inputs from 8-day Leaf Area Index and Fraction of Photosynthetically Active Radiation (LAI/FPAR) based on the Quality Control (QC) label for every pixel. If any LAI/FPAR pixel did not meet the quality screening criteria, its value is determined through linear interpolation.

However, users cannot get VJ217A3GF in near-real time because it will be generated only at the end of a given year. Provided in the VJ217A3GF product are layers for GPP, NPP, along with a quality control layer. A low resolution browse image for GPP is also available for each VJ217A3GF granule.
