• UV MEASUREMENT AND TRENDS

Item #d94mar94

"Temporal Trends in Surface Irradiance at Ultraviolet Wavelengths," C.G. Justus (New Techol. Inc., Huntsville, Ala.), B.B. Murphey, J. Geophys. Res., 99(D1), 1389-1394, Jan. 20, 1994.

Compares 1980-1984 measurements using a Robertson-Berger and an Eppley instrument to clarify conflicting results about temporal trends in surface UV irradiance. Discusses implications of results for long-term monitoring.

Item #d94mar95

"Evidence for Large Upward Trends of Ultraviolet-B Radiation Linked to Ozone Depletion," J.B. Kerr (Atmos. Environ. Serv., 4905 Dufferin St., Downsview ON M3H 5T4, Can.), C.T. McElroy, Science, 262(5136), 1032-1034, Nov. 12, 1993. (See GCCD, Dec. 1993, and related news item, ibid., p. 16.)

Item #d94mar96

"Biologically Effective Dose of Solar Ultraviolet Radiation Estimated by Spore Dosimetry in Tokyo Since 1980," N. Munakata (Radiobiol. Div., Natl. Cancer Ctr. Res. Inst., Chuoku, Tokyo 104, Japan), Photochem. & Photobiol., 58(3), 386-392, Sep. 1993.

The 30% increase observed in the late 1980s may be due to changes of solar activity, air pollution, or depletion of stratospheric ozone.

Item #d94mar97

"Seasonal Trends in Erythemal and Carcinogenic Ultraviolet Radiation at Mid-Southern Latitudes 1989-1991," G.J. Smith (DSIR-Phys. Sci., POB 31313, Lower Hutt, N.Z.), M.G. White, K.G. Ryan, ibid., 57(3), 513-517, Mar. 1993.

Short-term trends in New Zealand are attributed to a seasonal cycle in ozone levels and changes in atmospheric aerosols.

Item #d94mar98

"The Stratosphere as a Modulator of Ultraviolet Radiation into the Biosphere," K. Stamnes (Inst. Geophys., Univ. Alaska, Fairbanks AK 99775), Surveys Geophys., 14(2), 167-186, Mar. 1993. Reviews impacts of ozone depletion; identifies research needs; recommends actions.

Item #d94mar99

"Homogenisation and Trend Detection Analysis of Broken Series of Solar UV-B Data," X. Zheng (Natl. Inst. Water & Atmos. Res., Wellington, N.Z.), R.E. Basher, Theor. Appl. Clim., 47(4), 189-203, 1993. Monitoring in New Zealand suggests that UV-B radiation increased by about 6% from 1981-1990.

Item #d94mar100

"Distribution of Solar UV Radiation on the Ground and Its Response to Atmospheric Ozone Depletion," X. Xiaozhen (Inst. Atmos. Phys., Chinese Acad. Sci., Beijing 100029, China), W. Gengchen, Chin. J. Atmos. Sci., 17(4), 389-398, 1993. A 1% stratospheric ozone loss will cause a UV-B increase of 1% in winter and 0.6-0.7% in summer.
