Stratospheric Ozone Depletion/UV-B Radiation in the Biosphere [Paperback]

Do changes in stratospheric ozone relate to changes in UV-B irradiance and do both relate to life on Earth? This volume presents the latest data available in the basic scientific disciplines associated with these questions. The key topics are the interactive factors between the various research elements and the measurements needed to both validate ozone depletion and monitor UV flux changes in the biosphere.Proceedings of the NATO Advanced Research Workshop on Stratospheric Ozone Depletion/UV-B Radiation in the Biosphere, held in Gainesville, Florida, USA, June 14 - 18, 1993Do changes in stratospheric ozone relate to changes in UV-B irradiance and do both relate to life on Earth?
