MODIS/Terra+Aqua Albedo 16-Day L3 Global 500m SIN Grid V005

EDG Data Set Name	ShortName
MODIS/Terra+Aqua Albedo 16-Day L3 Global 500m SIN Grid V005	MCD43A3

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.

Shortwave White Sky Albedo is represented in this false-color image produced with data acquired between February 26 and March 13, 2001 over Central America including the Yucatan Peninsula, El Salvador, Honduras, Nicaragua, and some of Costa Rica (h09v07). Low albedos are noted as expected in inland water and coastal regions. Black color shows areas of deep ocean or persistent cloud cover.

Quality information stored as a separate product (MCD43A2)

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) Albedo product (MCD43A3) provides 500-meter data describing both directional hemispherical reflectance (black-sky albedo) and bihemispherical reflectance (white-sky albedo). These MCD43A3 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.
