Abstract:

The land surface temperature is all important parameter to hydrology and meteorology,it afects the exchange of sensible and latent heats between atmosphere,sea and land,and it cannot be lack in many research fields.To retrieve land surface temperature ex-aetly and quantifieationally will promote the development of research areas such as drought forecasting,crop yield estimating,numerical weather forecast,global climate change and carbon balance.Th erefore,retrieval of land surface temperature using thermal infrared re—mote sensing becomes one of the most important tasks in quantifieational remote sensing study.Th is article introduces the theory and methods of lan d surface temperature retrieval,and reviews their merit and insuficiency as well as the key questions in each method .Fi—naUy,it prospects the developing trend of land surface temperature retrieva1.

Key words: land surface temperature, single—window algorithm, split—window algorithm, retrieval of component temperature

摘要:

地球表面温度是一个重要的水文、气象参数,它影响着大气、海、陆之间的感热和潜热交换,是诸多研究领域不可或缺的基础资料,精确定量反演陆面温度的成果将推动旱灾预报和作物缺水研究、农作物产量估算、数值天气预报、全球气候变化和全球碳平衡等领域研究的进展。因此,利用卫星遥感资料进行地表温度的反演已成为目前遥感定量研究中的重要任务之一。本文阐述了遥感反演地表温度的原理及各种方法,对各种方法所要解决的关键问题及优缺点做了评述,最后展望了遥感反演地表温度的发展趋势。
