Historical Winter Precipitation (CONUS) (Image Service)

The National Forest Climate Change Maps project was developed to meet the need of National Forest managers for information on projected climate changes at a scale relevant to decision making processes, including Forest Plans. The maps use state-of-the-art science and are available for every National Forest in the contiguous United States with relevant data coverage. Currently, the map sets include variables related to precipitation and air temperature, including both Alaskan and lower 48 datasets. Data from the lower 48 were downloaded from here: https://www.fs.usda.gov/rm/boise/AWAE/projects/national-forest-climate-change-maps.html, and Alaskan data came from here: https://www.snap.uaf.edu/tools/data-downloads. Historical data are compared with RCP 8.5 projections from the 2080s. A Raster Function Template is available in this service that will classify the data as originally intended by OSC. The RFT currently works in AGOL but not in ArcGIS Pro.国家森林气候变化地图项目（National Forest Climate Change Maps）旨在满足国家森林管理人员对适配决策流程（含森林规划）相关尺度的预估气候变化信息的需求。本项目采用前沿科学方法，可向美国本土毗连区域内具备相关数据覆盖条件的所有国家森林提供服务。当前，该地图集涵盖降水、气温相关的多项变量，数据覆盖阿拉斯加及美国本土48州。美国本土48州的数据下载自以下链接：https://www.fs.usda.gov/rm/boise/AWAE/projects/national-forest-climate-change-maps.html，阿拉斯加数据则来源于https://www.snap.uaf.edu/tools/data-downloads。研究团队将历史数据与2080年代典型浓度路径8.5（RCP 8.5）的预估结果进行对比。本服务提供一款栅格函数模板（Raster Function Template），可按照OSC的原始设计意图对数据进行分类。该栅格函数模板目前可在ArcGIS Online（AGOL）中运行，但暂不支持ArcGIS Pro。
