NOAA-21 VIIRS Level-3 Global Mapped Particulate Organic Carbon (POC) - Near Real-time (NRT) Data, version 2025.0
Listed in NASA Earthdata CMR
The Ocean Biology DAAC produces near real-time (NRT) products using the best-available combination of ancillary data from meteorological and ozone data.
Description
As such, the inputs and the calibration used are less than optimal. Near real-time products provide a snapshot of the data during a short time period within a single orbit.
The Particulate Organic Carbon (POC) data suite includes product of particulate organic carbon concentration from ocean-color reflectance. POC is widely used to quantify surface carbon stocks, support biogeochemical and export-flux studies, and provide ecological context alongside chlor_a, bbp, Kd_490, and SST. Geophysical variables in this suite include: - poc - Particulate Organic Carbon (mg C m⁻³), D. Stramski, 2007 (443/555 version)
