MODIS/Terra+Aqua BRDF/Albedo Model Parameters Daily L3 Global 0.05Deg CMG V061

The Moderate Resolution Imaging Spectroradiometer (MODIS) MCD43C1 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 in a 0.05 degree (5,600 meters at the equator) Climate Modeling Grid (CMG). Data are temporally weighted to the ninth day of the retrieval period which is reflected in the Julian date in the file name. This CMG product covers the entire globe for use in climate simulation models. MCD43C1 provides the three model weighting parameters (isotropic, volumetric, and geometric) used to derive the Albedo (MCD43C3 (https://doi.org/10.5067/MODIS/MCD43C3.061)) and BRDF (MCD43C4 (https://doi.org/10.5067/MODIS/MCD43C4.061)) products. Each model parameter is available as a separate layer for MODIS spectral bands 1 through 7 as well as the visible, near infrared (NIR), and shortwave bands. Along with the 30 parameter layers there are ancillary layers for quality, local solar noon, percent finer resolution inputs, snow cover, and uncertainty. The MODIS BRDF/Albedo products have achieved stage 3 (https://modis-land.gsfc.nasa.gov/MODLAND_val.html) validation. 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).
