摘要
介绍了遥感传感器技术的发展,着重探讨了其在观察极地地区进行观测的适用性。极地地区与全球气候变化之间的关系和相互作用是气候变化研究的焦点。海冰的广泛覆盖对大气、海洋和极地地区特别是对其他地方的、其他进程的陆地和海洋生态系统产生重大影响。海冰覆盖了极地海洋广阔的区域,而两极地区的海冰受气候变化影响而产生的变化却不同,北极海冰面积减少趋势明显而南极海冰面积却有上升趋势。本研究回顾了海冰遥感领域的相关文献,评估不同传感器监测海冰物理特性的优势和劣势。分析了传感器的规格和获取的数据,概括了它们如何发展以满足用户不断增长的需求。同时,讨论了不同的遥感技术和观测方法及其在监测海冰变化方面的适用性。本文利用不同的数据集对海冰特性进行进一步的研究,总结了用于海冰监测的数据集以监测这些实地很难到达的区域。
Evolution of Technologies in Remote Sensing for Sea Ice Change Monitoring in Polar Regions is presented .The extent of in-fluence of polar regions on the global climate is the focus of climate change research .The extensive cover of sea ice has major impacts on the atmosphere , oceans , and terrestrial and marine eco -systems of the polar regions in particular .Sea ice covers vast areas of the polar oceans .However , both polar regions are witnessing contrasting rather contradicting effects of climate change .This paper reviews literature published in the field of sea ice remote sensing , to evaluate and access advantages and disadvantages of different sensors to observe physical features of sea ice .The sensor specifications and datasets are examined and how they have evolved to meet the grow -ing needs of users is outlined .Different remote sensing technology and observational methods and their suitability to observe specific sea ice variables are also discussed .This review suggests different primary datasets for further research on sea ice features ( sea ice ex-tent, ice type, sea ice thickness, etc.).The paper summarizes the useful datasets for sea ice monitoring to monitor these physically inaccessible regions .
