1. 2001 GOES-8/GOES-10/SURFRAD GOES-10/SURFRAD LST OBSERVATION CLR SKY DETECTION: Ming vs. Rama vs. Chuck
Figure 1 from (Vinnikov et al., 2008) is reproduced using Ming Chen Clear Sky data.
We use indices:
S or 1 – for SURFRAD LST
G8 or 2 – for GOES-8 LST
G10 or 3 - for GOES-10 LST
Function Y(t), used to approximate diurnal and seasonal variations of LST, contains two first harmonics of annual and two first harmonics of diurnal cycles.
