Historical Annual Temperature (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获取空间尺度适配决策流程（含森林规划）的预估气候变化信息的需求。该地图集采用前沿科学方法制作，覆盖所有具备有效数据覆盖范围的美国本土国家森林。当前，该地图集包含降水与气温相关的气候变量数据集，涵盖阿拉斯加数据集与美国本土48州数据集。美国本土48州的数据集下载自以下网址：https://www.fs.usda.gov/rm/boise/AWAE/projects/national-forest-climate-change-maps.html，阿拉斯加数据集则来源于：https://www.snap.uaf.edu/tools/data-downloads。研究将历史数据与2080年代典型浓度路径8.5（Representative Concentration Pathway 8.5, RCP 8.5）的气候预估结果进行了对比分析。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。当前该栅格函数模板可在ArcGIS Online（AGOL）中正常运行，但暂不支持ArcGIS Pro。
