VIIRS/NPP BRDF/Albedo Albedo Daily L3 Global 1km SIN Grid V001

Metadata Updated: June 4, 2024

The NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Bidirectional Reflectance Distribution Function (BRDF) and Albedo (VNP43MA3) Version 1 product provides albedo values at 1 kilometer (km) resolution for the bihemispherical reflectance white-sky albedo (WSA) and directional hemispherical reflectance black-sky albedo (BSA) at local solar noon. The VNP43MA3 product is produced daily using 16 days of VIIRS data and is weighted temporally to the ninth day, which is reflected in the file name. The VNP43 data products are designed to promote the continuity of NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) BRDF/Albedo data product suite.

The VNP43 algorithm uses the RossThick/Li-Sparse-Reciprocal (RTLSR) semi-empirical kernel-driven BRDF model, with the three kernel weights from (VNP43MA1) (https://doi.org/10.5067/VIIRS/VNP43MA1.001) to reconstruct surface anisotropic effects, correcting the directional reflectance to a common view geometry (VNP43MA4) (https://doi.org/10.5067/VIIRS/VNP43MA4.001), while also computing integrated black-sky albedo (BSA) at local solar noon and white-sky albedo (WSA) (VNP43MA3). Researchers can use the BRDF model parameters with a simple polynomial, to obtain black-sky albedo at any solar illumination angle. Likewise, both the BSA and WSA Science Dataset (SDS) layers can be used with a simple polynomial, to manually estimate instantaneous actual albedo (blue-sky albedo). Additional details regarding the methodology are available in the Algorithm Theoretical Basis Document (ATBD) (https://lpdaac.usgs.gov/documents/194/VNP43_ATBD_V1.pdf).

The VNP43MA3 product provides a total of 36 SDS layers including: BSA, WSA, and mandatory quality layers for nine VIIRS moderate bands: M1-M5, M7-M8, and M10-M11, as well as three broadbands: near-infrared (NIR), shortwave, and visible. A low-resolution image is also available showing retrievals of WSA for band I1 in JPEG format.
