Influence of Solar Radiation on the Diurnal and Seasonal Variability of O3 and H2O in the Stratosphere and Lower Mesosphere, Based on Continuous Observations in the Tropics and the High Arctic

Abstract

During the CAWSES DFG (German Research Association) priority program measurements of stratospheric and mesospheric O3 using ground based millimeterwave radiometry have been established and analyzed. Instruments have been operated at two different locations, at Mérida, Venezuela, a high altitude tropic station and at Ny Ålesund, Spitsbergen, an Arctic station. Additionally, data obtained from the millimeterwave radiometer based at Kiruna, Sweden, have been used for an analysis of the 5-day planetary wave.
