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

    Metadata Updated: February 22, 2025

    The Moderate Resolution Imaging Spectroradiometer (MODIS) MCD43A1 Version 6.1 Bidirectional Reflectance Distribution Function and Albedo (BRDF/Albedo) Model Parameters 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 retrieval period which is reflected in the Julian date in the file name. MCD43A1 provides the three model weighting parameters (isotropic, volumetric, and geometric) used to derive the Albedo (MCD43A3)(https://doi.org/10.5067/MODIS/MCD43A3.061) and BRDF (MCD43A4) (https://doi.org/10.5067/MODIS/MCD43A4.061) products.

    The MCD43A1 provides the three model weighting parameters for MODIS spectral bands 1 through 7 as well as the visible, near infrared (NIR), and shortwave bands. Along with the three-dimensional parameter layers for these bands are the quality layers for each of the 10 bands.

    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).
