			<title>New refinements and validation of the MODIS Land-Surface
				Temperature/Emissivity products</title>
			<abstract>This paper discusses the lessons learned from analysis of
				the Moderate Resolution Imaging Spectroradiometer (MODIS)
				Land-Surface Temperature/Emissivity (LST) products in the current
				(V4) and previous versions, and presents eight new refinements for
				V5 product generation executive code (PGE16) and the test results
				with real Terra and Aqua MODIS data. The major refinements include
				considering surface elevation when using the MODIS cloudmask
				product, removal of temporal averaging in the 1 km daily level-3 LST
				product, removal of cloud-contaminated LSTs in level-3 LST products,
				and the refinements for the day/night LST algorithm. These
				refinements significantly improved the spatial coverage of LSTs,
				especially in highland regions, and the accuracy and stability of
				the MODIS LST products. Comparisons between V5 LSTs and in-situ
				values in 47 clear-sky cases indicate that the accuracy of the MODIS
				LST product is better than 1 K in most cases (39 out of 47) and the
				root of mean squares of differences is less [...]</abstract>
