Data Products: Land surface bidirectional reflectance factor

The land surface bidirectional reflectance factor (BRF), also referred to as surface reflectance (SR), is a ratio between outgoing radiance at one given direction and incoming radiance at another given direction (same or different from the incoming direction). BRF is produced at the following wavelengths: 0.47 µm, 0.64 µm, 0.86 µm, 1.61 µm, and 2.26 µm. The land surface bidirectional reflectance factor is a byproduct of the land surface albedo algorithm. BRF is used to create the GOES-R fractional snow cover product and for vegetation monitoring.
