1. ENVISAT AO - ID:158: CINAMON: Characterisation, INterpretation, Application, and Maturation of key Ozone-related ENVISAT-1 level-2 products, using correlative observations associated with the NDSC

The present project aims at the geophysical validation, from pole to pole and on the long term, of key ozone-related level-2 products (O3, NO2, BrO, OClO, and ClO) from GOMOS, MIPAS and SCIAMACHY onboard ENVISAT-1, and at a contribution to the maturation of the related level-1b-to-2 data processors. Application data processing will be used to convert level-2 data into a more suitable format for validation and scientific end-users. The respective performances of the ENVISAT data products, and their sensitivity to various relevant parameters, will be investigated from the Arctic to the Antarctic, over a variety of geophysical conditions. The impact of these performances on specific atmospheric chemistry studies will be emphasised. The pseudo-global investigations will rely on correlative studies of ENVISAT data with high-quality ground-based, in situ and balloon observations associated with the Network for the Detection of Stratospheric Change (NDSC).

2. LAPBIAT Upper Troposphere Lower Stratosphere Water Vapor Validation Project: LAUTLOS - WAVVAP

The focus of this project is the improvement of water vapour measurement techniques in the upper troposphere and lower stratosphere. Routine measurements of water vapour with high accuracy in these altitudes are an unsolved problem of meteorological measurements up to now. Water vapor is the dominant greenhouse gas in the earth's atmosphere. Recent model calculations show that observed water vapour increases in the stratosphere contribute significantly both to surface warming and stratospheric cooling. In addition to climate change both the direct chemical and indirect radiative effects of stratospheric water changes in ozone chemistry are important as well. Despite of many activities in the past ten years, accuracies of the available methods for measuring the water vapour vertical profile in the free atmosphere are still not sufficient. Therefore one of the aims of the forthcoming EU COST Action 723 "The Role of the Upper Troposphere and Lower Stratosphere in Global change", is to improve sounding and remote sensing techniques of water vapour (see http://www.sat.uni-bremen.de/cost/). Another example of the planned work focusing on water vapour is proposed GEWEX (Global Energy an Water Cycle Experiment) Water Vapour Project (GVaP). See [SPARC 2000] and the references therein. The idea of LAUTLOS-WAVVAP comparison/validation experiment which brings together lightweight hygrometers developed in different research groups, which could be used as research-type radiosondes in UTLS region. These include the following instruments: Meteolabor Snow White hygrometer, NOAA frostpoint hygrometer, CAO Flash Lyman alpha hygrometer, Lindenberg FN sonde (a modification of Vaisala radiosonde) and the latest version of regular Vaisala radiosonde with humicap-polymer sensor. The experimental plan of LAUTLOS-WAVVAP is based on the regular launches of multi-sensor payloads from the Sodankylä meteorological balloon launch facility in January -February 2004. The aim is to study the effect of atmospheric conditions such as ambient temperature, water vapour or relative humidity, pressure or solar radiation for each participating hygrometer/radiosonde. Both night and daytime launches are planned. Apart from the intercomparison/validation experiment the campaign also have an scientific aim of studying the stratospheric PSC occurrence and their dependence on local temperature and the water vapour content. The campaign will be hosted by FMI Arctic Research Centre Sodankylä assisted by Vaisala Oyj and is a part of planned Finnish contribution to Cost 723 project. The campaign in Sodankylä is partly funded from LAPBIAT Facility, which belong to the EU program: Access to Research Infrastructures (see: http://www.sgo.fi/lapbiat/).

3. FUVIRC-Finnish Ultraviolet International Research Centre

FUVIRC will serve ecosystem research, human health research and atmospheric chemistry research by providing UV monitoring data and guidance (i.e. calibration of instruments, maintenance of field test sites), research facilities (laboratories and accommodation), instruments and equipment.

4. LAPBIAT-Lapland Atmosphere-Biosphere facility

The main objective of the facility is to enhance the international scientific co-operation at the seven Finnish research stations and to offer a very attractive and unique place for multidisciplinary environmental and atmospheric research in the most arctic region of the European Union. Factors such as, arctic-subarctic and alpine-subalpine environment, northern populations, arctic winters with snow, changes in the Earth's electromagnetic environment due to external disturbances and exceptionally long series of observations of many ecological and atmospheric variables should interest new users.

5. CANDIDOZ (Chemical and Dynamical Influences on Decadal Ozone Change)

The main objective is to establish a scientific basis for the detection of the earliest signs of ozone recovery due to Montreal protocol and its amendments. To achieve this we will select the best long-term ozone and meteorological data sets available (by ECMWF and NCEP). Ozone data will be studied by using advanced multiple regression methods developed in this project. Meteorological data would allow to determine the dynamical changes and trends and assess their role in re-distribution of stratospheric ozone in recent decades and in order to force the Chemical Transport Models to assess the relative roles of chemistry and transport in ozone changes. Finally, the synthesis of the key objectives will improve the attribution of observed ozone changes to anthropogenic influences and to the variations in a natural atmosphere.
