在二阶积雪散射模型模拟结果的基础上,针对GPM的数据特点,提出一种利用Ku波段不同入射角下积雪散射特征差异进行雪水当量监测的方法,并以TRMM/PR数据为例,对青藏高原部分特征地区进行了分析,证实了该方法在理论上的可行性。
This paper presents a method to monitor the snow water equivalent (SWE) change in the Tibetan plateau. The method is based on a second order snow model with the parameters of GPM data. Beside the numerical simulation, two typical areas of Tibetan plateau were chosen for the validation using the TRMM/PR data, which proved that the method is feasible.
