Such effects as atmosphere, the emissivity of sea surface are carefully considered and corrected to AVHRR data at band 10.5 ～11.5 μm to estimate the surface temperature distribution in the Bohai Sea. As a result, the estimate error is less than 0.6℃ related to the data measured by ships synchronously or quasi synchronously.展开更多
文摘In this paper, a linear model is developed to simplify the infrared radiation transfer complex in measuring valid thermal IR radiometric temperature from satellite platforms. Such effects as atmosphere, the emissivity of sea surface are carefully considered and corrected to AVHRR data at band 10.5 ～11.5 μm to estimate the surface temperature distribution in the Bohai Sea. As a result, the estimate error is less than 0.6℃ related to the data measured by ships synchronously or quasi synchronously.
