PACE OCI Level-2 Regional Surface Reflectance Data, version 3.1
Listed in NASA Earthdata CMR
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).
Description
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) - l2_flags — Level-2 Processing Flags (bitmask)
