Precipitation - Monthly and Annual Normals

<p>Monthly 30-year "normal" dataset covering the conterminous U.S., averaged over the climatological period 1991-2020. Contains spatially gridded average annual total precipitation at 4km grid cell resolution. Distribution of the point measurements to the spatial grid was accomplished using the PRISM model, developed and applied by Dr. Christopher Daly of the PRISM Climate Group at Oregon State University. This dataset is available free-of-charge on the PRISM website.</p>

本数据集涵盖美国大陆的30年月度‘正常’数据集，时间跨度为1991年至2020年气候学时期，数据平均。包含以4公里网格单元分辨率的网格化空间平均年降水量。点测量值分布至空间网格的工作由俄勒冈州立大学的PRISM气候小组的Christopher Daly博士开发的PRISM模型完成。此数据集可在PRISM网站上免费获取。” }
