Figure 2. Six scenes of the MOD021KM data from Zhongshan Station. The number of each scene consists of two parts, the year and the
Julian Day Number: “2008,” “2009,” “2010,” “2011,” “2012,” and “2013” are the years; “339,” “335,” “342,” and “358” are the Julian
Day Numbers: (a) 09 December 2008 (No. 2008-344), (b) 01 December 2009 (No. 2009-335), (c) 12 December 2010 (No. 2010-346),
(d) 06 December 2011 (No. 2011-340), (e) 27 December 2012 (No. 2012-361), and (f) 24 December 2013 (No. 2013-358)
Split-Window Algorithm Theory
The
SWA
is one of the multichannel
LST
retrieval methods. Its
principle is based on the relationship between the radiance
and temperature in the two infrared windows (the 11 to 12 μm
atmospheric window) for a given temperature. It was first pro-
posed by McMillin (1975), and was initially used to retrieve sea
surface temperature (
SST
). The
SWA
has also been further modi-
fied for
SST
retrieval (McClain
et al.
, 1985; Barton
et al.
