摘要:

作者基于Google Earth Engine平台,利用2020年夏季期间MODIS MOD11A1 Version 6.1日尺度地表温度产品,以全球干旱区618个孤立绿洲为研究对象,分别提取绿洲内部及其周边荒漠(缓冲区10 km)的夏季平均地表温度,其中北半球绿洲采用2020年6—8月,南半球绿洲采用2019年12月—2020年2月作为对应夏季时间窗,并依据公式OCI = T_desert − T_oasis计算绿洲冷岛强度,获得了618个孤立绿洲样点的冷岛强度及相关信息,整理为全球绿洲冷岛强度空间分布数据集(2020)。该数据集内容包括618个孤立绿洲样点的经度(°)、纬度(°)、荒漠平均地表温度(K)、绿洲平均地表温度(K)以及绿洲冷岛强度(°C),其中OCI > 0表示绿洲地表温度低于周边荒漠,存在冷岛效应,OCI < 0表示绿洲地表温度高于周边荒漠,表现为热岛特征。数据集以.xlsx和.shp格式储存,由8个数据文件组成,数据量为119 KB(压缩为1个文件,74.2 KB)。
