Item #d97jul45

"Analysis of Long-Term Behavior of Ultraviolet Radiation Measured by Robertson-Berger Meters at 14 Sites in the United States," E.C. Weatherhead (CIRES, Campus Box 449, Univ. Colorado, Boulder CO 80309; e-mail: betsy@srrb.noaa.gov), G.C. Tiao et al., J. Geophys. Res., 102(D7), 8737-8754, Apr. 20, 1997.

Evaluation of surface UV measurements over the period 1974-1991 initially showed a -6% per decade trend consistent with negative trends obtained by Scotto et al. (1998) using similar data. However, after allowing for mean level shifts at several stations, which may be related to calibration and other instrument problems, no significant trend was found. The authors attribute this to problems with the instrument network that render the existing measurements unreliable for long-term trends; different reasonable treatments of the data result in dramatically different trends. Future UV monitoring could be improved, for example, by providing ancillary data on visible radiation and intercomparisons with satellite information.


Item #d97jul46

"Systematic Long-Term Comparison of Spectral UV Measurements and UVSPEC Modeling Results," B. Mayer (Fraunhofer Inst. for Atmos. Environ. Res., Kreuzeckbahnstr. 19, D-82467, Garmisch-Partenkirchen, Ger.; e-mail: mayer@ifu.fhg.de), G. Seckmeyer, A. Kylling, J. Geophys. Res., 102(D7), 8755-8767, Apr. 20, 1997.

Evaluation of radiative transfer models, and investigations on the influence of parameters like aerosols or clouds on ground level UV, require a combination of spectral measurements and model calculations. This paper presents an efficient method for such a combination, and the results of a systematic comparison of the freely available UVSPEC radiative transfer model package with two years of spectrally resolved measurements.
