Land surface temperature (LST) and outgoing long wave radiation (OLR), which are commonly used in seismic monitoring, were compared and analyzed from their own characteristics and seismic applications. The analytical results of the global data show that LST and OLR at high latitudes and mid-latitudes have the consistency in spatial distribution, but show a significant difference in equatorial and low-latitude regions, and this difference is closely related to the global total cloud amount. The results of feature points selected according to the cloudiness distribution in China's mainland show that LST and OLR have poor synchronization in the region whose cloud amount is greater than 65% and show better synchronization in the region whose cloud amount is less than 65%. On such a basis, the authors selected Qinghai region where the synchronization is relatively good and mid-south China where the synchronization is poor as the test areas. The results achieved show that the spatial, temporal and intensity characteristics of two types of data can be either identical or different, as shown by the comparison between the two computing results using the vorticity method. LST mainly reflects the warming temperature phenomenon whereas OLR is focused on a comprehensive reflection of the whole earth-atmosphere system.
