Historical Summer Precipitation (Alaska) (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（National Forest Climate Change Maps）项目专为满足国家森林管理者的需求而开发，旨在为其提供与决策流程（包括森林规划）相适配尺度的预估气候变化相关信息。该地图集采用前沿科学方法制作，覆盖美国本土48州所有具备有效数据覆盖范围的国家森林。当前，该地图集涵盖降水与气温相关的多项变量，数据集覆盖阿拉斯加州与美国本土48州。美国本土48州的数据集下载自以下链接：https://www.fs.usda.gov/rm/boise/AWAE/projects/national-forest-climate-change-maps.html，阿拉斯加州数据集则下载自：https://www.snap.uaf.edu/tools/data-downloads。历史数据与典型浓度路径8.5（RCP 8.5）情景下2080年代的气候预估结果进行了对比。本服务提供栅格函数模板（Raster Function Template），可按照OSC最初的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）中使用，但暂不支持ArcGIS Pro。
