MODIS/Terra+Aqua BRDF Model Parameters 8-Day L3 Global 1km SIN Grid V006

Metadata Updated: March 23, 2019

The MCD19A3 Version 6 data product is a MODIS Terra and Aqua combined Multi-angle Implementation of Atmospheric Correction (MAIAC) Bidirectional Reflectance Distribution Function (BRDF) Model Parameters gridded Level-3 product which is output every 8th-day at 1 kilometer resolution. The MCD19A3 product provides three coefficients (weights) of the Ross-Thick Li-Sparse (RTLS) BRDF model that can be used to describe the anisotropy of each pixel. The retrievals represent cloud-free and low aerosol conditions. The MCD19A3 BRDF Model Parameters product contains the following Science Dataset (SDS) layers: RTLS isotropic kernel parameter (Kiso) for bands 1-8, the RTLS volumetric kernel parameter (Kvol) for bands 1-8 (Kvol), RTLS geometric kernel parameter (Kgeo) for bands 1-8, instantaneous surface albedo for bands 1-8, and the number of days since last update to current day. A low-resolution browse is also included.
