Individual projects

SCOUT-O3

The 'Stratospheric-Climate Links with Emphasis to the Upper Troposphere and Lower Stratosphere' project started in May 2004 and will last for five years. The central aims of the project are to proveide scientific knowledge for global assessments on ozone depletion and climate change for the Montreal and Kyoto protocols. That includes predictions about the evolution of the coupled chemistry/climate system, with emphasis on ozone change in the lower stratosphere and the associated UV and climate impact by a large range of state of the art chemistry climate models. SCOUT-O3 is funded by the European Commission in cooperation with national funding bodies. The SCOUT-O3 Tropical Aircraft Campaign data are stored at NILU.

POET

Precursors of Ozone and their Effects in the Troposphere. The overall objective of the project is to quantify accurately the budget of ozone precursors using a combination of observations and state of the art CTM.

COSE

Compilation of atmospheric Observations in Support of Satellite measurements over Europe. Any investigation related to Earth Observation (EO) is in need of coherent sets of validated EO data, with a well-known precision, accuracy and clearly documented qualities. The sources of such data are mainly found in the combination of satellite data, air-borne (aircraft, balloon) measurements and ground-based observations. COSE will provide the EO users community with a validated, consistent and well-documented data set of mainly stratospheric constituent columns and/or profiles which builds on past and ongoing time series, by co-ordination of ground-based observations at existing stations in Europe. The data will be archived in a dedicated database for immediate and future exploitation, e.g., satellite validation activities, data assimilation and scientific studies. Duration of project is 27 months (1.10.1998 - 31.12.2000)

MAPSCORE

Mapping of Polar Stratospheric Clouds and Ozone Levels Relevant to the Region of Europe. The MAPSCORE project was a three year programme to study ozone depletion over Europe and its relation to the formation of polar stratospheric clouds (PSCs). The project started on 1st January 2001 and ended om 31. December 2003. MAPSCORE is part of the GATO cluster and is contributing to the VINTERSOL campaign.

UFTIR

Time series of Upper Free Troposphere observations from a European ground based FTIR network. The experimental data of the project are spectral measurements from six stations in Europe, spanning 28°N to 80°N. The main specific objectives of UFTIR are to revise and homogenise the analyses of available experimental data for providing consistent time series of distinct tropospheric and stratospheric abundances of the target gases using new inversion algorithms. All time series are archived at NADIR. UFTIR started in February 2003 and will last for 30 months.

GMES-GATO

Global Monitoring for Environment and Security - Global Atmospheric Observations was an EU funded concerted action, which took place from January 2003 to January 2005. Its aim was to develope a strategy for global observations of atmospheric composition within GMES. Database was one out of five topics within GMES-GATO, and issues like user needs and harmonisation between different databases was adressed during the project.

ASSET

Assimilation of ENVISAT data is a European (EU) initative to exploit and develop earth observation data from ENVISAT using data assimilation. The project has two major activities and is aiming to exploit the satellite data in Numerical Weather Prediction (NWP) and investigate the distribution of chemical species. A third supporting activity covers data management, and the NADIR data center is used to make these value-added data available to the scientific community.

QUILT

QUILT (Quanitfication abd Interpertation of Long-Term UV-Visible Observations of the Stratosphere) started in January 2001 and ended in mid 2004. The EU funded project adressed stratospheric ozone depletion in particular, but did also focus on better exploitation of existing data, and on developement of new long-term observing capacity.QUILT used the existing ground-based, satellite and balloon borne UV-visible data as well as 3D atmospheric modelling tools for quantifying ozone loss and ozone developement, and to investigate its relation to active halogen and nitrogen species.

COZUV

Coordinated Ozone and UV project was a joint Norwegian project within stratospheric ozone and UV research. It started in January 1999 and ran through 2002. The main objectives were to gain increased understanding of the processes that lead to ozone loss in the Arctic and at middle latitudes and to understand how changes in the ozone layer affects the amount of UV radiation that hits the ground.

AEROZCLIM

AerOzClim (Aerosols, Ozone and Climate) is a natural continuation of the work laid down in COZUV. It started up in 2003 and will last for four years. The main objective of AerOzClim is to improve our understanding of aerosol-climate and ozone-climate interactions.

The role of NADIR

The NADIR data centre has played a central role in all these campaigns by acting as a central archive for both experimental data and meteorological data from ECMWF.
