Average precipitation and PET over Switzerland at 500m resolution

Long-term (1980-2011) average annual precipitation (pcp_ch_longterm_yr_avg.tif) and potential evapotranspiration (pet_ch_longterm_yr_avg.tif) at 500m resolution. Units are mm per year. Files are GeoTIFF rasters, and can be read in R using the command raster("pcp_ch_longterm_yr_avg.tif), after installing packages "raster" and "rgdal".

本数据集涵盖1980-2011年的长期平均年降水量（文件标识为pcp_ch_longterm_yr_avg.tif）与潜在蒸散量（文件标识为pet_ch_longterm_yr_avg.tif）两组数据，空间分辨率达500米，单位为毫米每年。所有数据文件均采用GeoTIFF栅格格式，可在R语言环境中，先安装"raster"与"rgdal"扩展包，随后通过命令`raster("pcp_ch_longterm_yr_avg.tif")`读取对应文件。
