JGR-Atmospheres：利用热红外卫星遥感获取全球陆地的每日蒸散发数据（图）
热红外卫星遥感 全球陆地 蒸散发数据

热红外遥感在研究地气相互作用方面有独特优势，但因受云的影响无法获得时空连续信息。近年来，可见光与微波遥感已被成功应用于计算全球地表蒸发，但是热红外还未被应用于估算全球蒸发。如何获得时空连续的地气间水分交换信息，是当前热红外遥感研究地气相互作用过程时遇到的“卡脖子”问题。国际上有观点认为基于能量平衡的热红外方法无法准确得到地表的蒸发，主要原因是蒸散发的估算对地气相互作用的水热传输阻力较敏感，并且受云...
基于多源遥感解译和野外验证的断裂几何展布——以西秦岭光盖山-迭山南麓断裂为例
光盖山-迭山断裂 几何展布 遥感影像解译 西秦岭
