基于卫星遥感的河流三角洲监测
Translated by Dr. Mengyi Jin
自古以来,河流三角洲因水资源丰富、土壤肥沃及交通便利而成为人类聚居的重要区域。这一格局延续至今。目前,生活在三角洲地区的人口已接近 60 亿,使其成为全球人口最稠密的地区之一(Kuenzer and Renaud 2011)。然而,这些三角洲地区正面临着气候变化、海平面上升、土地利用方式转变以及生态系统退化等威胁。遥感技术在获取环境状况及其时序变化方面具有显著优势,其在识别灾害前兆信号、预测自然现象演变等方面发挥着关键作用。在三角洲地区,遥感已被广泛应用于海岸线变化监测、洪水监测与预测等领域(Merkuryeva et al. 2015;Li and Damen 2010)。持续开展三角洲监测不仅有助于维护其生态功能,还能及时识别潜在风险,并为科学管理提供重要依据,而遥感正是实现这一目标的关键技术。

基于天基雷达的热带气旋监测和预报
Translated by Dr. Mengyi Jin
夏季来临时,热带气旋常在沿海地区引发洪涝灾害。早在古代,中国沿海的渔民就通过观察天气现象来预测热带气旋的来临,例如云层的形状和晚霞的变化。热带气旋发生在全球各地,不同地区对它的称呼也有所不同。在北大西洋、中北太平洋和东北太平洋地区,人们通常称之为“飓风”;而在西北太平洋地区,热带气旋常被称为“台风”。
近年来,热带气旋对美国、中国以及其他亚洲国家造成了重大损失。因此,发展基于太空的热带气旋监测技术,预测其路径并进行预警,对于保障民众的生命安全、保护渔业生产以及海上作业等具有重要意义。
双频降水雷达(Dual-frequency Precipitation Radar,简称 DPR)是由美国国家航空航天局(NASA)与日本宇宙航空研究开发机构(JAXA)联合开发的天基雷达系统,其搭载于热带降雨测量任务(TRMM)和全球降水观测计划(GPM)的卫星上(https://gpm.nasa.gov/missions/GPM/DPR),用于热带气旋的监测与科学研究(NASA,2018)。
