MODIS/Terra+Aqua BRDF/Albedo Model Parameters 16-Day L3 Global 1km SIN Grid V005

Version 005
  • Abstract
    The MODerate-resolution Imaging Spectroradiometer (MODIS) BRDF/Albedo Model Parameters product (MCD43B1) contains three-dimensional (3D) data sets providing users with weighting parameters for the anisotropy models used to derive the Albedo and NBAR products (MCD43B3 and MCD43B4). The models support the spatial relationship and parameter characterization best describing the differences in radiation due to the scattering (anisotropy) of each pixel, relying on multi-date, atmospherically corrected, cloud-cleared input data measured over 16-day periods. The BRDF/Albedo Model Parameters can be used with a simple polynomial to easily estimate the black-sky albedo with good accuracy for any desired solar zenith angle. BRDF shape and properties are further described by the shape indicators included in the product. 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 BRDF & Albedo products have attained Validation Stage 3. Change Points of Interest 1km and 500m products now available: the 1km product is an average of the 500m values (QA flags represent the majority situation) Quality information stored as a separate product (MCD43B2) Reduced file volume: internal compression Phased production strategy: Produced every 8 days with 16 days of acquisition (i.e., production period 2001001 includes acquisition between Days 001 and 016, production period 2001009 includes acquisition between Days 009 and 024) More: Collection 005 Change Summary for MODIS BRDF/Albedo (MCD43) Algorithms (http://landweb.nascom.nasa.gov/QA_WWW/forPage/C005_Change_BRDF.pdf) V005 Data Set Characteristics: Temporal Range: February 18, 2000 - March 29, 2017 Area: ~10 degrees x 10 degrees latitude/longitude File Size: ~11 MB Projection: Sinusoidal Data Format: HDF-EOS Image Dimensions: 1200 x 1200 rows/columns Resolution: 1 kilometer Science Data Sets (SDS HDF Layers): 11
