Description
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)

Variables
The table below lists the variables contained within a single granule for this dataset. Variables often contain observed or derived geophysical measurements collected from a variety of sources, including remote sensing instruments on satellite and airborne platforms, field campaigns, in situ measurements, and model outputs. The terms variable, parameter, scientific data set, layer, and band have been used across NASA’s Earth science disciplines; however, variable is the designated nomenclature in NASA’s Common Metadata Repository (CMR). Variable metadata attributes such as Name, Description, Units, Data Type, Fill Value, Valid Range, and Scale Factor allow users to efficiently process and analyze the data. The full range of attributes may not be applicable to all variables. Additional information on variable attributes is typically available in the data, user guide, and/or other product documentation.
For questions on a specific variable, please use the Earthdata Forum.
