MODIS/Terra+Aqua BRDF Model Parameters Daily NRT L3 Global 1km SIN Grid

Metadata Updated: December 6, 2023

The MODIS Near Real Time (NRT) Combined Terra and Aqua combined Multi-Angle Implementation of Atmospheric Correction (MAIAC) Bidirectional Reflectance Distribution Function (BRDF) Model Parameters gridded Level 3 product (MCD19A3DN) produced daily at 1 kilometer (km) pixel resolutions. The MCD19A3DN 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 Version 6.1 Level-1B (L1B) products have been improved by undergoing various calibration changes that include: changes to the response-versus-scan angle (RVS) approach that affects reflectance bands for Aqua and Terra MODIS, corrections to adjust for the optical crosstalk in Terra MODIS infrared (IR) bands, and corrections to the Terra MODIS forward look-up table (LUT) update for the period 2012 - 2017. A polarization correction has been applied to the L1B Reflective Solar Bands (RSB).
