Future Annual 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.

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）旨在满足美国国家森林管理人员在制定包括森林规划在内的各类决策时，对匹配决策尺度的气候变化预测信息的需求。该地图集采用前沿科学方法制作，可覆盖所有具备相关数据覆盖范围的美国本土国家森林。当前，该地图集包含与降水、气温相关的多类变量，涵盖阿拉斯加地区与美国本土48州的数据集。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，阿拉斯加数据集则源自https://www.snap.uaf.edu/tools/data-downloads。历史数据与2080年代典型浓度路径8.5（Representative Concentration Pathway 8.5，RCP 8.5）情景下的气候预测数据进行了对比。

本服务内置一款栅格函数模板（Raster Function Template），可按照OSC最初设定的分类目标对数据进行标注。该模板目前仅可在ArcGIS Online（AGOL）中使用，暂不支持ArcGIS Pro。

本数据集条目源自美国农业部企业数据目录（USDA Enterprise Data Inventory），该目录将数据同步至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（ArcGIS GeoService）。如需获取完整信息，请访问https://data.gov。
