UV MEASUREMENTS

Item #d95jan70

"Solar Ultraviolet Radiation and Total Ozone, as Derived from Satellite and Ground-Based Instrumentation," C. Varotsos (Dept. Appl. Phys., Univ. Athens, 33 Ippokratous Str., 106 80 Athens, Greece), Geophys. Res. Lett., 21(17), 1787-1790, Aug. 15, 1994.

Total ozone reductions of 2.5% in summer and 7% in winter in the last decade caused an increase in erythemally active UV-B irradiance of 5% and 14% respectively.

Item #d95jan71

Comment on UV-B and ozone observations, Science, 265(5173), 722, Aug. 5, 1994.

Item #d95jan72

"Erythemal UV-B Irradiance (Robertson-Berger Sunburn Meter Data) Under Ozone Deficiencies in Winter/Spring 1993," M. Blumthaler (Inst. Med. Phys., Univ. Innsbruck, 6020 Innsbruck, Austria), W. Ambach et al., Photochem. & Photobiol., 59(6), 657-659, June 1994.

Cumulative UV-B exposure of the ecosystem is within the general range of variability even under the record low ozone values in winter-spring 1993; single peak doses were enhanced significantly.

Item #d95jan73

"UV-B in Germany Higher in 1993 Than in 1992," G. Seckmeyer (Fraunhofer Inst. Atmos. Umweltforsch., Kreuzeckbahnstr. 19, 82467 Garmisch-Partenkirchen, Ger.), B. Mayer et al., Geophys. Res. Lett., 21(7), 577-580, Apr. 1, 1994.

Monthly averaged total ozone columns in 1993 were the lowest recorded in southern Germany. Data demonstrate the impact of clouds and aerosols which must be considered along with stratospheric ozone change when interpreting changes in UV-B irradiances.

Item #d95jan74

"Empirical Studies of Tropospheric Transmission in the Ultraviolet: Broadband Measurements," J.E. Frederick (Dept. Geophys. Sci., Univ. Chicago, 5734 S. Ellis Ave., Chicago IL 60637), A.E. Koob et al., J. Appl. Meteor., 32(12), 1883-1892, Dec. 1993.

Measurements in urban surroundings demonstrate that low-level gaseous air pollution has a detectable effect on ultraviolet radiation reaching the ground.

Specialized Papers
