PACE SPEXone Level-3 Global Mapped Land Properties, RemoTAP Algorithm - Near Real-time (NRT) Data, version 4.0
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.
AER_RTAPLAND provides aerosol and land‐surface properties over land retrieved using the RemoTAP algorithm. Because RemoTAP jointly models surface and atmosphere over land, the suite also provides spectrally resolved land-surface BRDF and BPDF parameters for reflectance and polarization. Typical uses: air-quality and climate studies, aerosol context for ocean-color/land analyses, radiative transfer, and model evaluation.
