Millennium Ecosystem Assessment: MA Climate and Land Cover

The Millennium Ecosystem Assessment: MA Climate and Land Cover provides data and information on global gridded climatological variables, global land cover maps, and national and international protected areas. The climatological data include the Climatic Research Unit (CRU) monthly terrestrial surface temperature and precipitation grids at 0.5 degree resolution from 1901-1996, along with temperature and precipitation grids at 10-minute resolution from the CRU and the International Water Management Institute (IWMI). The Global Land Cover 2000 (GLC2000) was produced by an international partnership of 30 research groups coordinated by the European Commission's Joint Research Centre (JRC), which contained two levels of land cover information; detailed and regionally optimized land cover for each continent, and a less thematically detailed global land cover that harmonizes regions into one consistent product. The maps were based on daily data from the Vegetation 1 sensor on-board SPOT 4, though mapping of regions required the use of data from additional Earth observing sensors to resolve specific issues. The international and national protected areas were generated from the World Database of Protected Areas for the year 2000.

千年生态系统评估（The Millennium Ecosystem Assessment）中的气候与土地覆盖数据集提供了全球格网化气候变量、全球土地覆盖图以及国家和国际保护区域的数据和信息。该气候数据包括从1901年至1996年的Climatic Research Unit（CRU）月度陆地表面温度和降水网格数据，分辨率为0.5度，以及来自CRU和国际水资源管理研究所（IWMI）的10分钟分辨率温度和降水网格数据。全球土地覆盖2000（Global Land Cover 2000，GLC2000）由欧洲委员会联合研究中心（Joint Research Centre，JRC）协调的30个研究小组的国际合作项目制作而成，包含两个层次的土地覆盖信息：针对每个大陆的详细和区域优化土地覆盖，以及一个主题性较为简略的全球土地覆盖，该覆盖将区域整合为一个统一的产品。地图基于SPOT 4卫星上Vegetation 1传感器的每日数据制作，而特定区域的映射则需要使用来自其他地球观测传感器的数据以解决特定问题。国际和国家级保护区域的数据来源于2000年的世界保护区域数据库。
