4. ATMospheric Fluxes from Arctic Snow Surfaces - ATMS

The central objectives of the proposed ATMAS project are:  to quantify the photo-chemically triggered NOx and HONO re-emission fluxes from permanently and seasonally snow-covered surfaces in the Arctic near Ny-Ålesund,  to quantify the sources of NO3 in these snow-covered surfaces. In detail, the following scientific objectives of ATMAS can be distinguished: 1. to quantify atmospheric gradient fluxes of HNO3, HONO, particulate nitrogen compounds, and nitrogen in precipitation (snow and rain) above snow surfaces; 2. to quantify the emission of NOx and HONO from the snow pack as atmospheric gradient fluxes 3. to formulate an influx-outflow relationship that can be used in dependence on the snow type for (photo-)chemical atmospheric process models. The results of this research may be expanded to a regional (European) or global scale, to suggest how the NOx and HONO re-emission process and its consequences can be included into regional emission, dispersion and deposition models used in Europe.

6. Measurement and Modeling the Mercury Depletion Events in the Arctic at the Ny-Ålesund Site

One of the major benefits of performing measurements at Ny-Ålesund is the availability of a monitoring station on Mount Zeppelin, 474m asl. Given the typical height of the Arctic inversion layer during the envisaged measurement period, it will be possible to continuously monitor mercury and particulate in the free troposphere at the same time as performing ground level monitoring. The simultaneous measurements above and below the boundary layer should provide evidence for the mode of elemental Hg replenishment, whether it is from due to exchange with the free troposphere, or transport occurring at sea level. The proposed collaboration, by collecting data from two strategically placed Arctic stations, in the paths of different air masses and data from above the Arctic inversion layer would provide the most comprehensive set of Arctic mercury measurements performed to date.

7. Chlorofluorocarbons, Hydrogenated Halocarbons and Degradation Products of the Hydrogenated Halocarbons in the Arctic Environment

Work program: Grab air samples will be collected in sampling sites not influenced by local emission sources for the determination of chlorofluorocarbons and of hydrogenated halocarbons. A 15 days sampling campaign is scheduled. Samples will be analysed in our Institution by using the analytical methodology here described and results obtained will be evaluated and compared with data obtained, by using the same analytical methodology, analysing air samples collected in other remote and semi remote sites. For the analysis of the hydrogenated halocarbon degradation products snow and water samples will be collected as well, according to the different season of the year. The collected samples will be then derivatized and analysed in our Institution for the evaluation of the presence of such compounds in remote areas.

8. ENVISAT AO ID 130: Global study of inorganic chlorine and fluorine loading in the Earth’s atmosphere, based on correlative measurements by ENVISAT-1 and at 10 NDSC sites

The project aims at producing an ENVISAT-1 mission-long monitoring of the inorganic chlorine (Cly) and fluorine (Fy) loading in the Earth’s middle atmosphere, based on FTIR vertical column abundance measurements of the key related species HCl, ClONO2, HF and COF2 at 10 ground-based NDSC sites distributed worldwide. These Cly and Fy inventories will be completed with ClO and OClO measurements expected as Level-2 products from ENVISAT-1. The column abundances of the source gases CFC-12 and HCFC-22 will be used to place the stratospheric Cly and Fy evolution in perspective with the more complete sets of organic chlorinated and fluorinated compounds measured at the ground by the in situ networks NOAA-CMDL and AGAGE. The assimilation of the retrieved geophysical data bases will be performed through 3-D model calculations incorporating physical, chemical and transport characteristics of the global atmosphere.

9. 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).

10. ENVISAT AO - ID:126: Validation of ENVISAT-1 level-2 products related to lower atmosphere O3 and NOy chemistry by an FTIR

The project will provide a long-term, pseudo-global validation support to the ENVISAT-1 atmospheric measurements, based on mutually consistent high-quality solar and lunar observations from FTIR spectrometers operated at primary and a number of complementary NDSC stations. The validation is limited to a number of target species, most of which are primary NRT or OL level-2 products of the mission, with focus on NOy components: O3, NO2, NO, N2O, HNO3, HNO4, H2CO, CO and CH4. Synergistic use will be made of column and profile data from MIPAS, GOMOS and SCIAMACHY. The ground network will deliver mean vertical column abundances for all target species with NDSC-type quality, and height profile information for some target gases as secondary products to the PI's home institute, where the correlative analyses with the ENVISAT-1 products will be done. Asynoptic mapping tools will support the validation efforts.

The main objectives of ESAC II are the following: (1) Extend and improve the important existing Belgian contribution in atmospheric research started in the 50s, recognized internationally. (2) Investigate the chemistry of the atmosphere, to detect and understand its evolution, mainly with experimental means. Special attention will be paid to the evolution of the ozone layer and chemical species and processes with an impact on climate changes. (3) Support the Belgian policies and decisions regarding the Amendments to: - the Montreal Protocol on Substances that deplete the Ozone Layer; - the Kyoto Protocol on Greenhouse Gases (GHG) emissions.

12. SOGE: System for Observation of halogenated Greenhouse gases in Europe

SOGE is an integrated system for observation of halogenated greenhouse gases in Europe. There are two objectives: (1) To develop a new cost-effective long-term European observation system for halocarbons. The results will be in support of the Kyoto and the Montreal protocols,in assessing the compliance of European regions with the protocol requirements. In particular the observation system will be set up to: - detect trends in the concentrations of greenhouse active and ozone-destroying halocarbons; - verify reported emissions and validate emission inventories; - develop observational capacity for all halocarbons included in the Kyoto protocol (PFC, SF6) for which this is presently not yet existing; - develop a strategy for a cost-effective long-term observation system for halocarbons in Europe. (2) To predict and assess impacts of the halocarbons on the climate and on the ozone layer. This implies extensive exploitation of existing data. The impact assessment will be aimed at providing guidance for development of the Kyoto protocol and to the further development of the Montreal protocol mendments, by: - modelling impacts of halocarbons on radiative forcing and their relative importance for climate change; - modelling impacts of emissions of CFCs and HCFCs on the ozone layer.

13. QUILT: Quantification and Interpretation of Long-Term UV-Vis Observations of the Stratosphere

The aim of QUILT is to optimise the exploitation of the existing European UV-visible monitoring systems by which O3 and the related free radicals NO2, BrO and OClO can be measured. These monitoring systems include ground-based, balloon and satellite observations. QUILT is providing an assessment of the chemical ozone loss over the last decade and through 2000-2003. This is achieved through analysis improvements, consolidation of existing datasets and near real time integrations with chemical transport models.

14. FREETEX (part of TROTREP): The Free troposphere experiment

The goals of this experiment are to map out the chemical changes in the free troposphere as the atmosphere transitions from winter to spring. It is hoped to begin to understand the chemical conditions that influence the lifetime of ozone and understand more about the productivity of this region of the atmosphere with respect to the in-situ production of ozone. How the free troposphere responds to changing levels of pollution could be critical to the development of future abatement strategies.

15. COSE: Compilation of atmospheric Observations in support of Satellite measurements over Europe

The overall objective of COSE is to provide the Earth Observation (EO) user community with a validated, consistent and well-documented data set of mainly stratospheric constituent columns and/or profiles, by co-ordination of ground-based observations at existing stations in Europe. The data set builds on past and ongoing time series, and will be archived in a dedicated database for immediate and future exploitation, e.g., satellite validation activities, data assimilation and scientific studies. Active participation of some representative EO customers will assure that the delivered data sets come up to their requirements.

16. UFTIR: Time Series of Upper Free Troposphere observations from a European ground-based FTIR network

The main specific objectives of UFTIR are: (1) 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. A common strategy for retrieval and characterisation of the vertical distributions of the target gases from FTIR ground-based measurements will be established. (2) To provide quantitative trends and associated uncertainties for the target gases over about the last decade, as a function of latitude throughout Western Europe, focusing on the troposphere. (3) To integrate the data in model assessments of the evolutions of tropospheric abundances. The measured burden and changes of the tropospheric gases will be compared with 3D model simulations, in order to help developing the latter, assist in explaining potential causes for the observed changes and to assess the consistencies between the trends at the surface to the free troposphere and lowermost stratosphere, and the agreement with known evolutions of emissions. UFTIR will make the community prepared to deliver tropospheric data for validation and synergistic exploitation of new satellite experiments like ENVISAT.

20. Determination of heavy metals in aerosols and deposition

Total deposition sampling is performed at Ny-Ålesund to study atmospheric fluxes of heavy metals to the Arctic. In addition wet only deposition sampling is carried out with an automatic precipitation sampler. The samples are analysed at the home laboratory for tracer elements for seaspray components, earthcrust weathered material and anthropogenic elements by atomic absorption spectrometry and inductively coupled plasma-mass spectrometry (ICP-MS). One aim of our study is to distinguish element distribution between the dissolved and particulate phase. In addition to the element analyses the concentration of anions is determined by ionchromatography. In 1996 an automatically operating aerosol sampler was installed, which is combined with the automatic precipitation sampler to study element washout from aerosol particles via rain and snow.
