The objective of the project is to develop the technology and the scientific interpretation and return of ground based spectrometric observations in the ultra-violet and the visible spectral region in particular for monitoring stratospheric ozone.
Ozone and several related stratospheric constituents (NO2, OClO, BrO, PSCs) can be monitored from the ground by ultraviolet and visible spectrometers. A network covering all latitudes from Northern to Southern Polar Regions, for photochemical investigation, observations of polar ozone depletion, PSC detection, long-term monitoring of constituents, early detection of changes of atmospheric composition and validation of satellite observations, is presently under deployment by the European institutions involved in this project. The first operational measurements started in January 1988.
The final goals of the present project are:
to ensure the homogeneity and accuracy of the data both in space and time, by the development of common data reduction and archiving processes, by intercomparison and improvement of calibration methods;
to increase the scientific return of the measurements and the accuracy, by appropriate model simulations of the atmospheric radiative transfer, photochemical reactions and large scale transport.
