National Environmental Monitoring in Sweden in the "Air" programme. The objective of the project is to follow climate-changing gases and particles and which effects they could have on the climate of earth. To understand and assess the human effect on the climate, regionally and globally, the atmospheric aerosols and greenhouse gases are monitored. The project aims follow: (i) detecting long-term trends in the carbon dioxide level, as well as trends in the amount or composition of aerosols in the background atmosphere; (ii) provide a basis to study the processes that control the aerosol life cycle from their formation through aging and transformation, until being removed from the atmosphere; (iii) provide a basis to study the processes (sources, sinks, and transport pathways) that control the level of carbon dioxide in the atmosphere; (iv) contribute to the global network of stations that perform continous measurements of atmospheric particles and trace gases to determine their effect on the earths radiation balance and interaction with clouds and climate.
Arctic study of trophospheric aerosol, clouds and radiation
The main objective is to quantify the levels of air pollution in the artctic, and to document any changes in the exposures. It includes the necessary components to address impacts on ecosystems, human health, materials and climate change.
monitoring of thermal and humidity parameters of arctic atmospheric boundary layer in horizontal and vertical profile covering glaciated area, non-glaciated area and mountain peak
The Arctic region represents a sensitive ecosystem, which is susceptible to even small changes in the local climate. Special conditions of usually high surface albedo and low solar elevations cause enhanced aerosol/cloud effects due to multiple scattering. It is suspected that this increased interaction between solar radiation and the aerosol particles/clouds magnifies their radiative impact. Thus, for a given aerosol distribution, the specific optical properties are enhanced in the polar regions. For the same reasons, results from field experiments at low latitudes are difficult to transfer to polar regions and as a consequence there is an urgent need to conduct specific measurement programs in high latitude regions. In order to improve the knowledge about the origin, transport pathways, vertical structure of aerosol physical and chemical properties as well as the impact on climate in the polar regions, a combined effort of surface-based, airborne and spaceborne measurements is needed. Therefore, this proposed project is aiming at a determination of the vertical structure of the chemical, physical and optical properties of Arctic aerosol particles, including solar radiative closure between observed and calculated aerosol properties (direct climate effect)
The IPY-project ‘COPOL’ has a main objective of understanding the dynamic range of man-made contaminants in marine ecosystems of polar regions, in order to better predict how possible future climate change will be reflected in levels and effects at higher trophic levels. This aim will be addressed by 4 integrated work packages covering the scopes of 1) food web contaminant exposure and flux, 2) transfer to higher trophic levels and potential effects, 3) chemical analyses and screening, 4) synthesis and integration. To study the relations between climate and environmental contaminants within a project period of four years, a “location-substitutes-time”-approach will be employed. The sampling is focussed towards specific areas in the Arctic, representing different climatic conditions. Two areas that are influenced differently by different water masses are chosen; the Kongsfjord on the West-coast of Spitzbergen (79N, 12 E) and the Rijpfjord North-East of Svalbard (80N, 22 E). The main effort is concentrated in the Kongsfjord. This fjord has been identified as particularly suitable as a study site of contaminants processes, due to the remoteness of sources, and for influences of climatic changes, due to the documented relation between Atlantic water influx and the climatic index North Atlantic Oscillation (NAO). The water masses of the Rijpfjord have Arctic origin and serves as a strictly Arctic reference. Variable Atlantic water influx will not only influence abiotic contaminant exposure, but also food web structure, food quality and energy pathways, as different water masses carry different phyto- and zooplankton assemblages. This may affect the flux of contaminants through the food web to high trophic level predators such as seabirds and seals, due to altered food quality and energy pathways.
This technological program aims to get a better view of the Corbel site quality (78 54 N, 12 07 E, Svalbard close to Ny Alesunsd) for atmospheric chemistry. Nox and SO2 samplers are deployed on 16 places on a 4 km2 area around the Station (79°N, Svalbard), protected from snowscooters activity. The influence of Ny Alesund village is also studied. Programme 2004 April 2004 : poles installation and samplers deployment on the 16 stations; analysis will be made by CNR.
The aims of the project are: - to evaluate the fluxes of radionuclides in the water column and their accumulation in the sediment, on a short-time scale; - to determine the C/N and delta13C-delta15N ratios in suspended and sedimentary matter, and test their use as tracers of origin, composition and transformation pathways of organic particles. The selected study area is the Kongsfjord-Krossfjord system, Svalbard, considered as representative test-site for studying processes occurring in Arctic fjords. The focus of the project will be on the processes occurring at the glacier-sea interface, where enhanced lithogenic and biogenic particle fluxes are reported in summer. Specific methods will be used to trace the particle sources. The rate of accumulation-resuspension processes will also be investigated from the inner fjord to the outer continental shelf.
Objective: to determine how solar activity influences temperatures, winds, electric currents and minor constituents and to allow possible anthropogenic influences to be determined. Uses primarily measurements by the ESRAD and EISCAT radars, plus ground-based and balloon-borne measurements of atmospheric electric fields and currents.
Study of the energy exchange between atmosphere, sea ice and ocean during freezing and melting conditions; within that, measurements of solar radiation (visible and UV) and optical properties, snow and sea ice characteristics, vertical heat and salt fluxes, oceanographic parameters.
To investigate arctic foxes physiological adaptations to life at high latitudes. Resting and running metabolic rates, body weight, food intake, body core temperature, heart rate, and blood parameters were examined during different seasons and during periods of food deprivation.
Monitoring of the active layer near Ny Ålesund as part of the international monitoring scheme CALM (Circumpolar Active Layer Monitoring)
To evaluate temporal variation in arctic fox numbers and their food resourses in the Kongsfjorden area. The number of foxes captured per 100 trap-days are used as an index of fox density termed "Fox Capture Index". The observations of denning activity i.e. observation of number of arctic fox litters and litter size at den are termed "Fox Den Index" as a second index of fox abundance. A third index is termed "Fox Observation Index". This index is based on both observations of adult foxes seen away from breeding dens pr 100 h field work and reports on request from scientists and local people on observations of adult foxes during summer. In addition, reports on observation of fox tracks in the study area were collected in 1990-2001 as a fourth index, which were called "Fox Track Index". The field census are conducted for 10 days starting at the end of June. All dead foxes in the area should be collected.
The objectives of this project is to study the effect of environmental stochasticity on the Svalbard reindeer population dynamics, nad further evaluate how this may affect reindeer-plant interactions.
ASTAR, Arctic Study of Tropospheric Aerosol and Radiation is a a joint German (AWI Potsdam) - Japanese (NIPR Tokyo) campaign with participation from NASA LaRC Hampton, VA (USA). In addition to AWI, NIPR, and NASA LaRC the following institutions contributed to the project: Hokkaido University (Japan), Nagoya University (Japan), Norwegian Polar Institute Tromsoe/ Longyearbyen (Norway), NILU Kjeller (Norway), MISU Stockholm (Sweden), NOAA-CMDL Boulder, CO (USA) and Max Planck Institute for Aeronomy Katlenburg-Lindau (Germany). The campaign is based on simultaneous airborne measurements from the German research aircraft POLAR 4 and ground-based measurements in Ny-Ålesund. The main goals of the project are - to measure aerosol parameters of climate relevance, like extinction coefficient, absoprtion coefficients and phase function. - to create an Arctic Aerosol Data Set for climate impact investigation by using the regional climate model HIRHAM. - to carry out comparison measurements with the SAGE II (Stratospheric Aerosol and Gas Experiment) and the ground based Raman-Lidar.
In preparation to the launch of the SAGE III experiment in March 2001, NASA and the European Union performed the SOLVE / THESEO-2000 campaign, which had three components: (i) an aircraft campaign using the NASA DC-8 and ER-2 airplanes out of Kiruna/Sweden, (ii) launches of large stratospheric research balloons from Kiruna, (iii) validation excercises for the commissioning phase of SAGE III. The German Arctic research station Koldewey in Ny-Ålesund/Spitsbergen contributes to (i), (ii), and (iii) by performing measurements of stratospheric components like ozone, trace gases, aerosols (PSCs), temperature and winds. The measurement results were transmitted quasi online to the flight planning center in Kiruna, in order to allow a better directing of the air plane flights. In addition the Koldewey-Station has been designated a validation anchor site for the SAGE III validation. The activities are organized within a NASA accepted proposal of ground-based validation support by the NDSC Primary Station at Ny-Ålesund, Spitsbergen and by a SAGE III validation working group for Ny-Ålesund. The main observation periods are from December 1999 to March 2000.
In order to get detailed vertical ozone profiles above the range of standard electrochemical ozonesondes (typically 35 km), a radiosonde together with an optical ozonesensor is launchend with a special plastic foliage balloon. The balloon payload consists of a digital radiosonde (DFM 90) using GPS for altitude measurements and a two channel filter spectrometer (optical sensor) to measure the vertical ozone distribution up to more than 40 km altitude. The ozone profiles obtained by the optical sensors will be compared with ground-based microwave and lidar ozone observations as well as with the standard balloon-borne ozone measurements with electrochemical ozone sensors.
The aim of the project is to study the properties (radiative effects, composition) of aerosols using FTIR emission spectroscopy. To determine seasonal changes in aerosol properties the measurements will be carried out year round on a weekly schedule.
The current scientific knowledge does not allow estimating accurately the surface radiative forcing caused by tropospheric aerosols and their influence on the evolution of the Earth climate. The radiative forcing depends on the optical properties of the aerosols at solar and thermal infrared wavelengths. These optical properties depend, in turn, on the chemical composition and size of the aerosols. Remote sensing with passive radiation sensors operating in the above-mentioned spectral ranges allows to measure the optical properties of the aerosols and to characterise their temporal variability. These data are needed for regional climate simulations of the Arctic, particularly for delineating the impact of the Arctic haze phenomenon. In this project, a synergetic effort will be made to obtain information about the radiative and microphysical properties of springtime arctic aerosols. Therefore, a polarisation-spectrometer for the solar spectral range, which is currently developed at the Free University of Berlin as a variant of the FUBISS spectrometer, will be operated from the surface in coincidence with the Fourier Transform InfraRed-spectrometer (FTIR) installed at Ny-Aalesund by the AWI. The former instrument measures the intensity and polarisation of the scattered solar radiation from the visible to the near-infrared. The latter measures the radiation emitted by the Atmosphere itself in the thermal infrared window region. Together, they thus provide a wealth of information about the aerosol optical properties at the interesting wavelengths (spectral optical depth, single-scattering albedo, and asymmetry factor of the phase function), which will allow inferring the aerosol microphysical properties. Complementary measurements of the aerosol microphysical properties will be provided by an aerosol volatility analyser, which is maintained by the University of Leeds and will also be brought to Ny-Aalesund. This instrument comprises a fast response scanning volatility system and an optical particle counter. From the thermal response of the aerosol number and the change in the size distribution conclusions can be inferred about the chemical composition and the state of mixing of aerosols as a function of size.
Aim of the project is to develop a cost-effective long-term European observation system for halocarbons and to predict and assess impacts of the halocarbons on the climate and on the ozone layer. Beside the routine observations within the NDSC it is planned to perform with FTIR (Fourier Transform Infrared Spectroscopy) absorption measurements of CFCs (e.g. SF6, CCl2F2, CHF2Cl) and related species on much more observation days.
