23. Metals in Mosses

An alternative for metal deposition measurements is to analyze their abundance in mosses since metals bind strongly to cation exchange sites in them. The concentration of metals in mosses would therefore act as an index for metal deposition. It is also assumed that uptake of most water and dissolved substances comes directly from precipitation; even if it has been shown that capillary transport of dissolved metals may be substantial. A national inventory of metals in mosses takes place at 5-year intervals (Table 4, #1.11). The two-to-three last years growth is identified and collected for chemical analysis ICP-AES and ICP-MS (As, Cd, Hg) Metals are adsorbed by mosses and metal concentration in mosses are therefore seen as a proxy for metal deposition. Moss species: Pleurozium schreberi, Hylocomium splendens Analyzed metals: As, Cd, Cr, Cu, Fe, Hg, Ni, Pb, V, Zn Sampling sites: More than 700 sites over Sweden Time period: 1/5 years, first report 1975 and last reported 2005.

24. IRF ozone and other trace gases monitoring + aerosols + thin clouds + wind/structures + atmospheric composition + particle precipitation + ionosphere

The total column amount of ozone and other trace gases are measured with mm-wave instruments, FT-IR and DOAS spectrometers, at IRF in Kiruna (Table 6, #8.1). With the sun or moon as infrared light sources, FT-IR spectrometers can quantify the total column amounts of many important trace gases in the troposphere and stratosphere. At present the following species are retrieved from the Kiruna data: O3 (ozone), ClONO2, HNO3, HCl, CFC-11, CFC-12, CFC- 22, NO2, N2O, NO, HF, C2H2, C2H4, C2H6, CH4, CO, COF2, H2O, HCN, HO2NO2, NH3, N2, and OCS. Together with Russian and Finnish institutes at the same latitude, IRF studies the stratospheric ozone and its dependence on polar atmospheric circulation and precipitation of charged particles. The ground-based instruments are also used to validate satellite measurements of vertical ozone distribution (Odin, SAGE III, and GOME). Aerosols and thin clouds are measured at IRF in Kiruna. For example, researchers use Lidars (Light Detection and Ranging) to measure polar stratospheric and noctilucent clouds. Winds and structures are measured with ESRAD MST radar at IRF in Kiruna. At IRF in Kiruna measurements are used to assess the physical and chemical state of the stratosphere and upper troposphere and the impact of changes on the global climate. Particle precipitation is measured by relative ionospheric opacity meters (riometers) at IRF in Kiruna. Riometers measure the absorption of cosmic noise at 30 and 38 MHz and provide information about particles with energies larger than 10 keV. The electron density of the ionosphere is measured by ionosonds and digisondes at IRF in Kiruna.

27. IVL Throughfall network

Deposition measurements are mainly made in forest injury observation plots laid out by the Swedish Forestry Agency (SST). The observations made are: Air Chemistry: SO2, NO2, NH3, O3 Soil Water Chemistry: pH, Alk, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn, Fe, ooAl, oAl, Al-tot, TOC Deposition open field precipitation: H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn Deposition in forest throughfall: H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn A notorious problem in deposition assessments is dry deposition on forest canopies. If throughfall is sampled below the canopy it will consist not only of dry and wet deposition, but also of canopy leakage, i.e. exudates and diffusion of substances from within the leaves. However, it has been argued that throughfall sampling, even if not free from problems, may add information to the normal wet deposition sampling. IVL operates a throughfall sampling network comprised of 10 forest sites for sampling, from which monthly samples are analyzed for pH, SO4, NO3, NH4, Kjeldahl-N, Cl, K, Ca, Na, Mg, TOC, conductivity, alkalinity, and amount of throughfall.

28. SMHI Mesoscale Atmospheric Transport and Chemistry Model (MATCH)

Calculating deposition in a grid over Sweden showed the lack of information on deposition at high altitude. SMHI applied the meso scale MATCH model to calculate the deposition field and the matched model is called MATCH-Sweden. The result is found at http://www.smhi.se/cmp/jsp/polopoly.jsp?d=5640&l=sv The observations made at these stations are: Particles in air: SO4-S, NO3-N, NH4-N, Cl, Na, Ca, Mg, K Gase:s NH3-N, HNO3-N, SO2-S Deposition open field precipitation: H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K Deposition in forest throughfall: H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K To integrate the relatively few deposition measurement sites, SMHI has adopted the Mesoscale Atmospheric Transport and Chemistry Model (MATCH) that uses emission data, meteorological data, routines for chemical processes, and a transport model to calculate long-range transport and deposition of air pollutants (Table 4, #1.5). Time series of gridded data over Sweden for deposition of different inorganic chemical compounds calculated with the MATCH-Sweden model are available at SMHI (Appendix, Table 11). When the MATCH-Sweden model was first tested, the deposition network lacked high elevation sites. Hence, a monitoring program for deposition at higher elevations (Table 4, #1.9) was started. It consists of 4 sites in high elevation forests along the Swedish mountain ridge, where NO3, NH4, NH3, HNO3, SO2, SO4, Na, K, Ca, Mg, Cl, pH, conductivity, and amount of precipitation are analyzed on monthly accumulated precipitation samples.

30. Air and Precipitation Chemistry Network (PMK)

The PMK Network is part of the national network for deposition measurements. The aim is a longterm monitoring concentration and deposition of different air transported compounds. The aim is also to generate knowledge about longterm variation in the deposition field, and to give background data from low polluted areas for calculation of pollution deposition in more polluted areas. The Air and Precipitation Chemistry Network includes about 25 sites (14 in northern Sweden) where precipitation from open accumulating samplers are collected and analyzed for pH, SO4, NO3, NH4, Cl, Ca, Mg, Na, K, conductivity, and amount of precipitation (Table 4, #1.2). At 3 sites (one in northern Sweden) precipitation is analyzed for heavy metals, mercury, and methyl-mercury (Table 4, #1.3).

31. IOANA

The project IOANA proposes to better understand the intimate coupling between ozone mixing ratios and particulate nitrate isotopic characteristics. Ozone Depletion Events which occur in Arctic coastal locations shortly after sunrise are a subject of interest per se (scientifically challenging for two decades) but also provide a context in which ozone mixing ratios are highly variable, enabling to characterize the dynamic of correlation and process studies with a resolution of a day. This is a first step towards the use of the isotope tool in reconstructions of the oxidative capacity of the atmosphere. This programme is a preparation of the IPY-OASIS project and propose to coodinate a set of collaborations than will be effective duing the International Polar Year.

32. 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.

34. Long-term effects of offshore discharges on cold water zooplankton: establishing a test system for chronic exposure to offshore discharges

During the last decade the concern regarding environmental effects of the offshore industry has shifted from effects of drilling discharges on benthic communities, towards a stronger focus on the water column and effects on the pelagic ecosystem. At the same time, oil and gas development is expanding in the Norwegian and Russian sectors of the Barents Sea. In this regard, a project has been initiated to look at responses of especially Calanus spp. and other copepod species to long-term, sublethal exposure to selected offshore discharges and discharge components, as well as accidental oil spills. Calanus spp. is ecologically the most important zooplankton species along the Norwegian shelf and in the Barents Sea. A laboratory based facility for culture through several generations is being developed through this project. In addition, the impact of oil compounds on the cold-water and arctic Calanus species-complex will be examined by carrying out a series of laboratory (some at Ny Ålesund) and ship based experiments. The response parameters will include both behavioral (feeding, mate finding, avoidance) and physiological (mortality, egg production, development rates, oxygen consumption and assimilation efficiency) parameters. The ultimate outcome of this research is expected to be a supporting instrument for ecological risk assessment of offshore discharges, which is highly relevant both to the North Sea, the mid-Norway shelf and the Barents Sea.

38. 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.

39. 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).

40. 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.
