PACE OCI Level-3 Global Mapped Surface Reflectance - Near Real-time (NRT) Data, version 3.1
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.
Surface Reflectance (SFREFL) provides the unitless, bottom-of-atmosphere reflectance of the Earth’s surface at 122 wavelengths (346 - 895 nm, with 5 SWIR bands). Surface Reflectance is the foundational input for downstream land products (e.g., vegetation indices included in the LANDVI suite). Users should review the documentation for more information on atmospheric correction and quality flags.

Users should also note that the L3M product is masked for clouds. Geophysical variables in this suite include: - rhos – Surface reflectance (unitless)
