Future 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.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旨在满足国家森林管理人员对契合决策流程（包括森林规划）所需尺度的预估气候变化相关信息的需求。该地图集采用顶尖科学方法制作，覆盖所有具备有效数据覆盖范围的美国本土48州国家森林。当前，该地图集包含降水与气温相关的变量数据，涵盖阿拉斯加与美国本土48州两类数据集。美国本土48州的数据下载自以下网址：https://www.fs.usda.gov/rm/boise/AWAE/projects/national-forest-climate-change-maps.html，阿拉斯加数据则来源于https://www.snap.uaf.edu/tools/data-downloads。研究中将历史数据与2080年代的典型浓度路径8.5（RCP 8.5）预估情景进行了对比。本服务提供栅格函数模板（Raster Function Template, RFT），可按照OSC原定意图对数据进行分类。当前该模板仅可在ArcGIS Online（AGOL）中使用，暂不支持ArcGIS Pro。本数据集条目来源于美国农业部（USDA）企业数据目录库，该库的数据会同步至https://data.gov公开目录。本条目包含以下资源：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS地理服务（GeoService）。如需获取完整信息，请访问https://data.gov。
