Historical Winter 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旨在满足美国国家森林管理人员对适配决策流程（含森林规划）尺度的预估气候变化信息的需求。本地图集采用前沿科学方法制作，可面向数据覆盖范围内的美国本土所有国家森林提供服务。当前，该地图集涵盖降水量与气温相关的各类变量，包含阿拉斯加地区及美国本土48州的数据集。美国本土48州的数据集可从以下链接获取：https://www.fs.usda.gov/rm/boise/AWAE/projects/national-forest-climate-change-maps.html，阿拉斯加地区数据集则来源于：https://www.snap.uaf.edu/tools/data-downloads。研究将历史数据与2080年代的典型浓度路径8.5（Representative Concentration Pathway 8.5，简称RCP 8.5）气候预估结果进行对比。本服务提供栅格函数模板（Raster Function Template，简称RFT），可按照OSC的原始设计意图对数据进行分类。目前该栅格函数模板可在ArcGIS Online（AGOL）中正常使用，但暂不支持ArcGIS Pro。
