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

The MCD19A3 Version 6 data product is a Moderate Resolution Imaging Spectroradiometer (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 8 days at 1 kilometer resolution. The MCD19A3 product provides three coefficients (weights) of the RossThick/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, RTLS geometric kernel parameter (Kgeo) for bands 1-8, surface albedo for bands 1-8, and the number of days since last update to current day. Three low-resolution browse images are also included showing the BRDF coefficients for the red band: (1) Kiso, (2) Kvol, and (3) Kgeo.
