Validation of satellite stratospheric ozone related observations with ground-based and balloon measurements of ozone, NO2, BrO,OClO, H2O and polar stratospheric clouds

Cel

The objective of the project is the validation of stratospheric and tropospheric chemistry measurements by European satellites already in orbit (GOME-ERS2) or anticipated to be placed into orbit during the next two years (ODIN and ENVISAT) or to which European teams have direct access to the data through special agreements (POAM III, SAGE III). Emphasis will be put on Arctic areas where large ozone losses have been reported and where the chemical composition of the stratosphere is highly variable.

The work programme consists of two different activities : the collection of the ground-based, balloon and sondes data largely already supported by national and European funding within the frame of the Third European Stratospheric Ozone Experiment (THESEO) in 1999; and the interpretation of those data in term of comparison with satellite observations, for testing and improving the respective retrieval algorithms of the instruments in orbit.

The experimental data consists of:
i) ground-based measurements of total ozone, NO2 and Polar Stratospheric clouds at a number of stations in the Arctic including two in Eastern (Zhigansk) and Western (Salekhard) Siberia run by Russian institutes;
ii) short and long duration balloon measurements of a number of relevant species including water vapour measured by a Lyman alpha hygrometer developed in Russia;
iii) ozone, aerosol and water vapour sondes operated at Yakutsk in Siberia.

The analysis and interpretation will be conducted in cooperation between INTAS and NIS institutes after short stays of young scientist at French and Belgium laboratory already experienced in satellite validation. Two rounds are anticipated: the first year dedicated to the validation of GOME-ERS2 already in orbit and POAM III and ODIN, both to be launched in 1998; and the second year dedicated two the two satellites (ENVISAT and SAGE III) expected to be placed into orbit in 1999.

The two INTAS members are the CNRS Service d'Aeronomie in France, directly involved in POAM III, ODIN, SAGE III and GOMOS-ENVISAT, short and long duration balloon experiments and ground-based uv-vis spectrometry, and the Institut d'Aeronomie Spatiale de Belgique (IASB) involved in GOME-ERS2 and SCIAMACHY-ENVISAT and ground-based uv-visble spectrometry as well.
Three NIS institutes are contributing: the Central Aerological Observatory of Moscow experienced in ozone satellite measurements (NASA -TOMS instrument onboard the Russian METEOR 3), in ozone, aerosol and water vapour sondes, and ground-based spectrometry; AviaecoCenter and the Salekhard Committee for Environment, responsible for the exploitation of uv-vis spectrometer at Zhigansk and Salekhard respectively and the sondes operations at Yakutsk and Salekhard.

The total cost of the project is 60 000 Ecus among which 36 000 Ecus are devoted to grants to young Russian scientists, 12 000 Ecus to the uv-vis spectrometers operation in Siberia and 12 000 Ecus for travel, workshop and coordination.
