This publication contains proceedings from the fourth European symposium on polar stratospheric ozone held in Schliersee, Bavaria from 22 to 26 September 1997. The purpose of the symposium was to discuss the results of the winter 1996/97 research activities and the plans for the third European stratospheric experiment on ozone (THESEO) which will take place during 1998-1999. Extensive field measurements were performed during the northern hemisphere winter of 1996/97. Several projects, involving remote sensing and in-situ instruments, investigated the formation and properties of polar stratospheric clouds (PSC) over northern Scandinavia in winter. More than twenty large balloons launched from Kiruna in northern Sweden and a number of aircraft flights were made over western and northern Europe. Studies of the evolution of ozone and of ozone loss were performed using measurements from ozone sondes and from ground-based instruments, as well as from the global ozone monitoring experiment (GOME) satellite instrument. The symposium discussed all these measurements under four sessions covering long-term variability, PSCs and aerosols, chemical partitioning and transport. These sessions were followed by a session concerning the THESEO plans. The fulfillment of the scientific aims in all three components of THESEO (sub-tropics, polar vortex and mid-latitudes) was critically examined.
