Average annual humidity rate in Andalusia: 1971-2000

Layer of geographic information in raster format that represents the humidity index in Andalusia in the period 1971 - 2000. The humidity index is a climate indicator that relates the variables precipitation and potential evapotranspiration, in this case obtained by the Thornthwaite method. This indicator allows to establish a reference from which to assess desertification processes.本数据集为栅格格式（raster format）的地理信息图层，展示了1971年至2000年期间安达卢西亚（Andalusia）地区的湿度指数。湿度指数是关联降水与潜在蒸散量的气候指标，本数据集的该指数通过桑特维特法（Thornthwaite method）计算得到。该指标可作为评估荒漠化进程的参照基准。
