SAFARI 2000 MODIS L3 ALBEDO AND LAND COVER DATA, SOUTHERN AFRICA, DRY SEASON 2000

The Filled Land Surface Albedo Product for Southern Africa, which is generated from MOD43B3 Product (the official Terra/MODIS-derived Land Surface Albedo - http://geography.bu.edu/brdf/userguide/albedo.html ), is a subset of the global data set of spatially complete albedo maps computed for both white-sky and black-sky at 10 wavelengths. The data spatial extent is from approximately 5 degrees N to -30 degrees S latitude and 5 minutes E to 60 degrees E longitude and covers 7 sixteen day periods starting on July 11 through October 15, 2000.Map Products, containing spatially complete land surface albedo data, are generated at 1-minute resolution on an equal-angle grid. The maps are stored in separate HDF files for each wavelength, each 16-day period and each albedo type (white- and black-sky). Data belonging to black sky and white sky albedo have been zipped separately. This format allows the user to have flexibility to download and store only the data absolutely needed.The One-Minute Land Ecosystem Classification Product is a global (static map) data set of the International Geosphere-Biosphere Programme (IGBP) classification scheme stored on an equal-angle rectangular grid at 1-minute resolution. The dataset is generated from the official MODIS land ecosystem classification dataset, MOD12Q1 for year 2000, day 289 data (October 15, 2000). This dataset is used in generating the spatially complete albedo maps, but is also a stand-alone product designed for use by the user community. The Land Ecosystem Classification Map File product file is stored in Hierarchical Data Format (HDF).

本数据集为南非填充地表反照率产品（Filled Land Surface Albedo Product for Southern Africa），其基于MOD43B3产品（官方Terra/MODIS地表反照率产品——http://geography.bu.edu/brdf/userguide/albedo.html）生成，属于全球完整空间覆盖反照率数据集的子集，该全球数据集针对10个波段的白空反照率（white-sky）与黑空反照率（black-sky）进行计算。数据空间覆盖范围为北纬约5°至南纬30°，东经5′至东经60°，时间跨度涵盖2000年7月11日至2000年10月15日的7个16天周期。地图产品包含完整空间覆盖的地表反照率数据，以等角网格为基准，分辨率为1弧分。每个波段、每个16天周期以及每种反照率类型（白空与黑空反照率）的数据均存储于独立的HDF文件中。黑空与白空反照率数据分别进行压缩打包，该设计可使用户仅按需下载和存储所需数据，提升使用灵活性。一分钟分辨率陆地生态系统分类产品（One-Minute Land Ecosystem Classification Product）为全球静态地图数据集，采用国际地圈-生物圈计划（IGBP）分类体系，以等角矩形网格存储，分辨率为1弧分。该数据集基于2000年第289天（即2000年10月15日）的官方MODIS陆地生态系统分类产品MOD12Q1生成，既可用于生成完整空间覆盖的反照率地图，同时也作为独立产品供用户群体使用。陆地生态系统分类地图文件以分层数据格式（Hierarchical Data Format, HDF）存储。
