The papers presented in this volume have been divided into three main chapters. Firstly Atmospheric Trace Species which is primarily concerned with the construction of a COSPAR International Reference Atmosphere (CIRA -Volume 3) for trace constituents of the middle atmosphere and lower thermosphere. Possible reference models and data were presented on a number of trace species including background stratospheric aerosols, polar stratospheric clouds, methane, nitrous oxide, ozone, water vapor, thermospheric nitric oxide, molecular oxygen airglow emissions, atomic oxygen and atomic hydrogen. Chapter 2 entitled Equatorial Thermosphere and Aeronomy: Models and San Marco Satellite/Ground Based observations reflects the advances made recently in equatorial aeronomy and demonstrate the promise of coordinated measurements using satellite measurements in conjunction with sounding rockets and ground-based experiments. The final chapter, Coupling of Dynamical, Radiative and Chemical Processes in the Middle Atmosphere examines the ozone hole and related atmospheric chemistry and modelling.
