MODIS/Terra+Aqua BRDF/Albedo Quality Daily L3 Global - 500m V061

Metadata Updated: May 22, 2024

The Moderate Resolution Imaging Spectroradiometer (MODIS) MCD43A2 Version 6.1 Bidirectional Reflectance Distribution Function and Albedo (BRDF/Albedo) Quality dataset is produced daily using 16 days of Terra and Aqua MODIS data at 500 meter (m) resolution. Data are temporally weighted to the ninth day of the 16-day retrieval period which is reflected in the Julian date in the file name. MCD43A2 contains the quality information for the corresponding MCD43A3 (https://doi.org/10.5067/MODIS/MCD43A3.061) Albedo and MCD43A4 (https://doi.org/10.5067/MODIS/MCD43A4.061) Nadir BRDF-Adjusted Reflectance (NBAR) products.

The MCD43A2 contains BRDF/Albedo band quality (inversion information) and days of valid observation within the 16-day period for MODIS bands 1 through 7 along with land water type, snow BRDF albedo, local solar noon, platform, and BRDF/Albedo uncertainty.

Improvements/Changes from Previous Versions

  • 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
