摘要:
应用被动微波遥感热带降雨测量卫星（TRMM）降水量数据结合中分辨率成像光谱仪（MODIS）地表温度产品，建立了降水温度指数模型,用于旱涝灾害的监测。该指数参考了地表温度与植被指数特征空间反演地表水分的方法，同时考虑了降水量和地表温度2个因素，并将旱灾和涝灾的监测结合起来。应用水系所在区域的降水温度指数的统计值，确定了涝灾的值域范围；应用AMSR-E土壤湿度数据，确定了旱灾的值域范围。结果表明，降水温度指数旱灾监测结果与条件温度指数监测结果一致，降水温度指数涝灾监测结果与标准化降水指数监测结果一致，且与历年相关的新闻报道相符。说明降水温度指数可以用来进行旱涝灾害监测。
Abstract:
A new precipitation-temperature index (PTI) was developed based on precipitation data from passive microwave remote sensing of tropical rainfall measurement mission (TRMM) and moderate-resolution imaging spectroradiometer (MODIS) land surface temperature products in this study. The new index is not only related to precipitation changes in a region, but also gives emphasis on land surface temperature changes, aiming at integrated monitoring of both drought and flood disasters. The performance of temperature. The PTI pixels in the central Taihu Lake and Hongze Lake were applied to determine the flood line of PTI. ASMR-E soil moisture data was used to determine the drought line of PTI. The performance of temperature condition index (TCI) was consistent with PTI when applied to monitor drought, while standardized precipitation index (SPI) agreed well with PTI in monitoring flood disasters. The results indicated that PTI is capable of integrated monitoring of drought and flood disasters.
