Above:  The western hemisphere subset from the MCD43C4 product shows two prominent white patches in North and South America.  Using the MCD43C4's Percent_Snow SDS shown on the right, it is evident that the white in North America is primarily snow cover, while the white in South America is persistent cloud.

V005 Change Points of Interest:  

•  4D Science Data Sets simplified to 2D structure
•  Snow-free parameters and quality available in new product (MCD43C2)
•  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 MCD43C4 provides reflectance data adjusted using a bidirectional reflectance distribution function (BRDF) to model the values as if they were taken from nadir view. MCD43C4 data are 16-day composites provided as a level-3 product projected to a 0.05 degree (5600-meter) latitude/longitude Climate Modeling Grid (CMG).

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.
