Percent Change in Summer 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.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog. Data for this record includes the following resources: ISO-19139 metadata ArcGIS Hub Dataset ArcGIS GeoService For complete information, please visit https://data.gov.

国家森林气候变化地图项目（National Forest Climate Change Maps project）旨在满足国家森林管理人员对与决策流程（包括森林规划）相适配尺度的预估气候变化信息的需求。该地图采用前沿科学方法制作，可面向美国本土所有具备相关数据覆盖范围的国家森林提供服务。当前地图集涵盖与降水、气温相关的变量数据集，包含阿拉斯加及美国本土48州的相关数据。其中美国本土48州的数据下载自：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年代的典型浓度路径8.5（Representative Concentration Pathway 8.5，RCP 8.5）预估结果进行对比分析。本服务提供一款栅格函数模板（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）中正常运行，但暂不支持ArcGIS Pro。本数据集记录取自美国农业部企业数据清单（USDA Enterprise Data Inventory），该清单同步至https://data.gov开放数据目录。本记录包含以下资源：ISO-19139元数据（metadata）、ArcGIS Hub数据集（ArcGIS Hub Dataset）、ArcGIS地理服务（ArcGIS GeoService）。如需获取完整信息，请访问https://data.gov。
