VERTICAL PROFILES OF AEROSOL OPTICAL THICKNESS OVER SYOWA STATION, ANTARCTICA
Attenuation measurements of solar irradiance using an airborne sun photometer were performed for the first time over Syowa Station, Antarctica. The NIPR's Cessna 185 aircraft equipped with a sun photometer (Eko, Model MS-111) took 4 flights during JARE-25,on January 19,September 3,December 25 a...
