Papers are invited with the focus on: new systems and methods for determination of Solar UV radiation from ground and from space; development of UV instruments and networks; climatological and case study investigations of the spectral, temporal and spatial variability of solar UV radiation due to variable atmospheric conditions (e.g. aerosols, clouds, ozone); effects of solar UV on men, biosphere and air chemistry.
Subsession (planned 1/2 Day) - Title: Traceability of solar UV radiation to SI.
Description: This subsession will be dedicated to developments of instruments and techniques for unambiguous quantification of future changes in solar UV radiation.
