MODIS/COMBINED MCD43C2 BRDF-Albedo Snow-Free Quality 16-Day L3 Global 0.05Deg CMG

The MODerate-resolution Imaging Spectroradiometer (MODIS) BRDF/Albedo Model Parameters product (MCD43A1) contains three-dimensional (3D) data sets providing users with weighting parameters for the models used to derive the Albedo and BRDF products (MCD43A3 and MCD43A4). 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.
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.

中分辨率成像光谱仪（Moderate-resolution Imaging Spectroradiometer，MODIS）的双向反射分布函数（Bidirectional Reflectance Distribution Function，BRDF）/反照率模型参数产品（MCD43A1）包含三维数据集，可为用户提供用于反演反照率与BRDF产品（MCD43A3、MCD43A4）的模型权重参数。该模型可表征空间关系与参数特征，最优描述各像元散射（各向异性）引发的辐射差异，其依赖于16天周期内采集的多时序、经大气校正与云剔除处理的输入数据。
本产品生成过程中同时采用Terra与Aqua卫星的观测数据，以最大程度保障输入数据的质量，因此将其归类为MCD产品，即组合型（Combined）产品。
