Quantitative Understanding of Ozone losses by Bipolar Investigations (QUOBI)

Updated 2003-03-06

By launching several hundred ozonesondes at many Arctic and sub-Arctic stations, one of them Ny-Ålesund, the stratospheric chemical ozone loss will be determined. The launches of all stations will be coordinated by analysis of trajectory calculations based on analysis and forecast wind fields. The aim is to get as many ozone sounding pairs as possible, each of them linked by trajectories in space and time. A statistical description of the ozone differences given by the first and the second measurement of individual sonde pairs will yield the chemical ozone loss with spatial and time resolution.
