MODIS/Terra+Aqua Nadir BRDF-Adjusted Reflectance 16-Day L3 Global 500m SIN Grid V005
MCD43A4
Unlike MODIS V004 MOD43, the V005 BRDF, Albedo, and NBAR products are known as MCD43. Whenever possible, both Terra and Aqua data are used in the generation of the new V005 products, providing the highest probability for quality input data and designating them as "MCD," meaning "Combined," products.

V005 Change Points of Interest:
500-m product now available
3D Science Data Sets simplified to 2D structure
Quality information stored as a separate product (MCD43A2)
Solar Zenith Angle changed from mean to angle at local solar noon
Reduced file volume: internal compression
Phased production strategy: Produced every 8 days with 16-days of acquisition (ie., production period 2001001 includes acquisition between Days 001 and 016, production period 2001009 includes acquisition between Days 009 and 024)
Product Description
The MODerate-resolution Imaging Spectroradiometer (MODIS) Reflectance product MCD43A4 provides 500-meter reflectance data adjusted using a bidirectional reflectance distribution function (BRDF) to model the values as if they were taken from nadir view. These MCD43A4 data are 16-day composites provided as a level-3 gridded product in the Sinusoidal projection.
Both Terra and Aqua data are used in the generation of this product, providing the highest probability for quality input data and designating it as an “MCD,” meaning “Combined,” product.
Version-5 MODIS/Terra+Aqua BRDF/Albedo products are Validated Stage 1, meaning that accuracy has been estimated using a small number of independent measurements obtained from selected locations and time periods and ground-truth/field program efforts. Although there may be later improved versions, these data are ready for use in scientific publications.
