Atmospheric effects against the surface temperature measurement by AVHRR in the polar region

Atmospheric effects against the surface temperature measurement by the AVHRR infrared sensors in the polar region are simulated by the LOWT-RAN-6 computer program. The atmospheric transmittance and radiance are calculated using the monthly average of the aerological data at Syowa and Mizuho Stations...

Description
Summary:Atmospheric effects against the surface temperature measurement by the AVHRR infrared sensors in the polar region are simulated by the LOWT-RAN-6 computer program. The atmospheric transmittance and radiance are calculated using the monthly average of the aerological data at Syowa and Mizuho Stations, Antarctica, and those at Tateno Aerological Observatory for comparison. The atmospheric transmittance at Syowa and Mizuho Stations is larger than 0.9 throughout the year and the brightness temperature detected by the AVHRR infrared sensors is within 1.0 of difference from the surface temperature.
