报告主题:The long path of satellite-retrieved Land Surface Temperature (LST) to maturity: recent advances in LST retrieval and product validation.

报告人:德国卡尔斯鲁厄理工学院 Frank-Michael G?ttsche 博士

报告时间:2018年7月19日(星期下午14:30

报告地点:创新中心5楼D518议室

主讲内容:

Since 2017 LST is an essential climate variable (ECV) as specified by the Global Climate Observing System (GCOS). However, for a meaningful scientific use of satellite LST products reliable information on their uncertainty has to be available. The most accurate and established method to obtain such information is the validation against in situ LST; this approach is complicated by the fact that field measurements cannot be controlled to the same extent as laboratory measurements. Karlsruhe Institute of Technology (KIT) addressed this issue by setting up permanent LST validation stations in naturally homogenous sites, e.g. on the vast gravel plains of the Namib Desert. An overview of KIT’s sites and the methods used to obtain in-situ LST is given and results from an international field inter-comparison experiment are presented. The ESA GlobTemperature project is briefly introduced, which aims at fostering the uptake of LST satellite data sets by a wider user community, e.g. by providing satellite and in-situ LST in a common, harmonized data format. The presentation concludes with results from two recently available algorithms, which are capable of retrieving LST and land surface emissivity simultaneously and thereby open up new applications for thermal infrared satellite data.
