摘要

干旱是一种毁灭性自然灾害,对环境和社会都有深远影响。预测干旱的发生对于帮助决策和实施有效的缓解战略具有重要意义。在南部非洲等数据可用性有限的地区,卫星遥感数据的使用为实现这一预测目标提供了绝佳机会。在本文中,我们利用多元线性回归预测数据和全球陆地数据同化系统(GLDAS)土壤水分数据,评估了土壤水分主动被动式(SMAP)和旋风全球导航卫星系统(CYGNSS)土壤水分数据在预测干旱状况方面的有效性。

Evaluation of SMAP and CYGNSS Soil Moistures in Drought Prediction Using Multiple Linear Regression and GLDAS Product
Drought is a devastating natural hazard and exerts profound effects on both the environment and society. Predicting drought occurrences is significant in aiding decision-making and implementing effective mitigation strategies. In regions characterized by limited data availability, such as Southern Africa, the use of satellite remote sensing data promises an excellent opportunity for achieving this predictive goal. In this article, we assess the effectiveness of Soil Moisture Active Passive (SMAP) and Cyclone Global Navigation Satellite System (CYGNSS) soil moisture data in predicting drought conditions using multiple linear regression???predicted data and Global Land Data Assimilation System (GLDAS) soil moisture data.
