SHIVA - Stratospheric Ozone: Halogen Impacts in a Varying Atmosphere

Partners

Ruprecht-Karls-Universität Heidelberg, Germany (UHEI)

logo iupheidelbergThe Institute for Environmental Physics at the University of Heidelberg was founded in 1973. It is among the world-wide leading institutions that address environmental problems by means of physical methods. At present the major scientific foci of the Institute span from paleo-climatological information stored in deep- sea sediments, ice cores and tree rings, ground water, the hydrological cycle in soil water, the impact of pollutants on the photochemistry of the atmospheric ozone and the climate to the radiative transfer and the solar energy deposition in the cloudy atmosphere. Besides other scientific techniques, differential optical absorption spectrometry (DOAS) that will be applied for the present studies has been extensively developed at this institute. Present applications of DOAS comprise ground-based zenith scattered skylight and artificial light long-path absorption measurements, measurements from aircrafts (Falcon, HALO), stratospheric balloons, and satellite platforms (GOME and SCIAMACHY) as well as with the newly developed high resolution oxygen A-band spectrometry. Within the present project the Institute will contribute through the analysis of aircraft measurements and solar occultation spectra taken during a series of low, mid, and high- latitude stratospheric balloon flights since 1996.

Tasks within SHIVA:

  • Coordination of the project
  • To ensure an efficient project management partner 1 (UHEI) will employ a project manager (Work package leader of WP-1)
  • Partner 1 will contribute through the performance and analysis of DOAS aircraft measurements (WP-2).
  • The Institute will contribute to an assessment of brominated and iodinated radical concentrations in the tropical TTL and lower stratosphere as input for WP-4
  • Trends in the stratospheric bromine loading will be derived from past and planned balloon-borne DOAS BrO measurements (WP-5)
