Abstract :
This paper, based on surface energy balance theory, examined the feasibility of drought monitoring by MODIS LST product. Maximum Value Compositing method, which is widely used in cloud-contaminated-data compositing, was examined with other two land surface temperature products, that is, maximum land surface temperature deviation from air temperature and standardized thermal index (STI). All three products were calculated and correlated with soil moisture condition. And we found that STI was the best choice for drought monitoring.
