  2. ISLSCP II MODIS (COLLECTION 4) ALBEDO, 2002

The MODIS BRDF/Albedo Product (MOD43B) provides measures of clear sky surface albedo every 16 days. Both white-sky albedo (bihemispherical reflectance) and black-sky albedo (directional hemispherical reflectance) at local solar noon are provided for 7 spectral bands and 3 broadbands. Since black-sky albedo represents the direct beam contribution while white-sky represents the completely diffuse contribution, these measures can be linearly combined as a function of the fraction of diffuse skylight (itself a function of optical depth) to provide an actual or instantaneous albedo at local solar noon. This data set provides albedo data for the period January 2002 through December 2002. Albedo Quality Information is provided as follows: Mandatory QA(Band 1), BRDF Quality(Band 2), Percent Snow(Band 3), Local Solar Noon(Band 4), Percent Contribution of pixels to input(Band 5).
