dc.description.abstract | Temporal characteristics of total ozone amount and solar radiations are investigated using the updated data from satellite and ground-based measurements at King Sejong station in West Antarctica during the period from 1995 to 2001. Solar radiations are composed of horizontal global solar irradiance(285∼3000 nm; GL), surface UV irradiance(290∼385 nm; UV), erythemal UV-B irradiance(280∼315 nm; EUV-B) and TOMS-EUV irradiance(280∼400 nm). Total ozone amount was measured from the satellites NOAA/SBUV and Earth Probe/TOMS and Brewer ozone spectrophotometer at King Sejong station. Horizontal global solar irradiance, surface UV irradiance and erythemal UV-B irradiance are directly measured by using Eppley Pyranometer, Eppley Photometer and Robertson-Berger UV-Biometer at King Sejong station. TOMS-EUV irradiance around King Sejong station was obtained from Nimbus-7/EP TOMS data erythemally weighted since 1979. Annual mean value of total ozone was 276 DU with maximum of 303 DU in December and minimum 237 DU in September. Annual mean values of GL, UV, EUVB and TOMS-EUV were 7.16 MJm-2day-1, 0.48 MJm-2day-1, 1.13 kJm-2day-1 and 2.07 kJm-2day-1, respectively. The regression analyses indicate significant trends of decrease 15.3 %/decade for total ozone while for TOMS-EUV, increase 25.2 %/decade during September and October which is a season occurring strong ozone loss in the lower stratosphere over Antarctica. Radiative amplification factor for EUV-B irradiance was 1.15, 1.59 and 1.58 at solar zenith angles of 60o, 70o and 80o, respectively. | - |
