Data covering soil microbial carbon use efficiency and soil properties along an aridity gradient

Data including experiment description, site geographic location, climate variables, soil microbial carbon use efficiency and soil properties along an aridity gradient. The aridity index data were derived from the Global Aridity Index and Potential Evapotranspiration Climate Database v3, which is available to download from the figshare (https://figshare.com/articles/dataset/Global_Aridity_Index_and_Potential_Evapotranspiration_ET0_Climate_Database_v2/7504448/4).
