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.
GAW serves as an early warning system to detect further changes in atmospheric concentrations of greenhouse gases and changes in the ozone layer, and in the long-range transport of pollutants, including acidity and toxicity of rain as well as the atmospheric burden of aerosols.
Monitoring of air quality and deposition.
Monitoring of direct deposition. Project is run by Finnish Meteorological Institute (FMI).
The overall objectives for operation of the station will follow those defined in the AMAP programme. The main interests are the levels and trends of airborne toxic pollutants (POPs and heavy metals) in northern Fennoscandia.
The project aims at establishing a long-term Arctic-Antarctic network of monitoring stations for atmospheric monitoring of anthropogenic pollution. Based upon the long and excellent experiences with different scientific groups performing air monitoring within the Arctic Monitoring and Assessment Programme (AMAP), an expanded network will be established including all AMAP stations and all major Antarctic “year-around” research stations. As an integrated project within the “International Polar Year 2007-08” initiative, the ATMOPOL co-operation intend to • Establish a long-term coordinated international Arctic-Antarctic contaminant programme. • Develop and implement a joint sampling and monitoring strategy as an official guideline for all participating stations. • Support bi-polar international atmospheric research with high-quality data on atmospheric long-range transport of contaminants (sources, pathways and fate). • Support future risk assessment of contaminants for Polar Regions based on effects of relevant contamination levels and polar organisms Based upon the well-established experiences of circum-Arctic atmospheric contaminant monitoring in the Arctic under the AMAP umbrella, a bi-polar atmospheric contaminant network will be established and maintained. In conjunction with the polar network of atmospheric monitoring stations for air pollution, surface-based and satellite instrumentation will be utilised to provide the characterization of the Arctic atmospheric-water-ice cycle. Together with numerical weather prediction and chemical transport model calculations, simultaneous measurements of pollutants at various locations in the Arctic and Antarctic will enhance our understanding of chemical transport and distribution as well as their long-term atmospheric trends. In addition to investigating the importance of atmospheric transport of pollutants an understanding of the transference and impact of these pollutants on both terrestrial and marine environments will be sought. A secretariat and a “scientific project board” will be established. During this initial phase of the project (2006), a guideline on priority target compounds, sampling strategies, equipment and instrumentation, analytical requirements, as well as quality assurance protocols (including laboratory intercalibration exercises) will be developed and implemented. The ATMOPOL initiative aims to address highly relevant environmental change processes and, thus, will strive to answering the following scientific questions: • How does climate change influence the atmospheric long-range transport of pollutants? • Are environmental scientists able to fill the gaps in international pollution inventories and identification of possible sources for atmospheric pollution in Polar Regions? • What are the differences in transport pathways and distribution patterns of various atmospheric pollutants between Arctic and Antarctic environments? Why are there such differences? What is the final fate of atmospherically transported pollutants and how does this impact on the environment and indigenous people?In order to understand the underlying atmospheric chemistry of pollution, e.g. atmospheric mercury deposition events, routine surface measurements of UV radiation as well as campaign related measurements of UV radiation profiles will also be included.The project will establish a cooperative network on atmospheric contaminant monitoring in Polar Regions far beyond the IPY 2007/08 period and is, thus, planned as an “open-end” programme. All produced data will be available for all participating institutions for scientific purposes as basis for joint publications and reports from the ATMOPOL database to be developed.
The Collaborative Interdisciplinary Cryospheric Experiment (C-ICE) is a multi-year field experiment that incorporates many individual projects, each with autonomous goals and objectives. The science conducted has directly evolved from research relating to one of four general themes: i. sea ice energy balance; ii. numerical modeling of atmospheric processes; iii. remote sensing of snow covered sea ice; and iv. ecosystem studies.
To see whether the features in the annual cycle of mercury is a local phenomena for Alert in the Canadian Arctic or also apply to larger ares in the Arctic. To quantify the concentrations/depositions of biological available mercury (reactive gaseous mercury and particulate mercury) in the Arctic environment during polar sunrise
To regularly deploy buoys in the Arctic to measure atmospheric temperature and pressure at various drifting sites.
In 2000 it is proposed to operate an atmospheric programme consisting of a monitoring and a modelling part and composed of 3 programme modules. The monitoring programme consists of two parts. I. It is proposed to continue the weekly measurements of acidifying components and heavy metals at Station Nord in north-east Greenland for assessment of atmospheric levels and trends. The measuring programme includes also highly time resolved measurements of Ozone and of total gaseous Mercury (TGM). The results will also be used for continued development and verification of the transport model calculations. Receptor modelling of the pollution composition will be used for identification and quantification of the source types that influence the atmospheric pollution in north-east Greenland. Comparison of the two sets of modelling results is expected to give better models. II. The purpose of the project is the operation of a permanent air monitoring programme in the populated West Greenland at a location which is representative for transboundary air pollution. The most promising sites are located in the Disko Bay area and in the vicinity of Nuuk. The objectives are to obtain data on the concentration levels of air pollutants that can be used for assessing seasonal variations and trends and for studying long range transport of pollutants mainly from North America to West Greenland. The purpose is further to provide data for development and improvement of long range transport models that can be used to identify the origin of the pollution and its transport pathways. The results from measurements and model calculations will be used to assess the magnitude of deposition to sea and land in this populated region of Greenland. III. In the proposed modelling programme the operation, application and maintenance of the current basic hemispheric model will be continued. Results on origin, transport, and deposition of contaminants on land and sea surfaces in the Arctic are essential for interpretation and understanding the Arctic air pollution. The model will be developed to improve the spatial and temporal resolutions, as well as the accuracy by including physically and mathematically better descriptions of the key processes treated in the model. The work to expand the model to include also non-volatile heavy metals, such as Cadmium and Lead on an hemispheric scale will be continued. Since the atmospheric chemistry of Ozone and Mercury seem to be strongly connected in the Arctic it is planned to continue the development and testing of a model module for hemispheric transport and chemistry for ozone and mercury to assess the origin and fate of this highly toxic metal in the Arctic.
This project aims to establish continuous Total Gaseous Mercury (TGM) measurements at Amderma, Russia to provide circumpolar data in concert with international sampling efforts at Alert (Nunavut, Canada), Point Barrow (Alaska, USA) and Ny-Ålesund (Svalbard/Spitsbergen, Norway). The objectives of this project are to determine spatial and temporal trends in atmospheric mercury concentrations and deposition processes of mercury in the Arctic in order to assist in the development of long-term strategies for this priority pollutant by: A) measuring ambient air TGM concentrations in the Russian Arctic; B) investigating and establishing the causes of temporal variability (seasonal, annual) in mercury concentrations so that realistic representations (models) of atmospheric pathways and processes can be formulated, tested and validated; and C) studying the circumpolar behaviour of mercury by comparison with data from other polar sites.
The objectives of the project are: A) to determine temporal trends in atmospheric mercury concentrations and deposition processes of mercury in the Arctic, and to assist in the development of long-term strategies for this priority pollutant by: i) measuring ambient air Total Gaseous Mercury (TGM) concentrations in the Canadian Arctic (Alert) and investigating the linkage to elevated levels of mercury known to be present in the Arctic food chain; ii) investigating and establishing the causes of temporal variability (seasonal, annual) in mercury concentrations so that realistic representations (models) of atmospheric pathways and processes can be formulated, tested and validated; iii) studying the chemical and physical aspects of atmospheric mercury vapour transformation (oxidation) after polar sunrise and the resultant enhanced mercury deposition to the sea, snow and ice surfaces each year during springtime; and iv) obtaining a long-term time series of atmospheric mercury (TGM) concentrations at Alert for the purpose of establishing whether mercury in the troposphere of the northern hemisphere is (still) increasing and if so, at what rate; B) to establish a sound scientific basis for addressing existing gaps of knowledge of the behaviour of mercury in the Arctic environment that will enable international regulatory actions to reflect the appropriate environmental protection strategies and pollution controls for the Arctic by: i) studying the relative roles of anthropogenic and natural sources of mercury so as to clarify understanding of the atmospheric pathways leading to the availability of mercury to Arctic biota; ii) studying tropospheric TGM depletion mechanisms/processes leading to enhanced input of mercury to the Arctic biosphere in spring; iii) undertaking essential speciated measurements of particulate-phase and/or reactive gaseous-phase mercury as well as mercury in precipitation (snow/rain) to quantify wet and dry deposition fluxes into the Arctic environment; and vi) providing the scientific basis for the information and advice used in the preparation and development of Canadian international strategies and negotiating positions for appropriate international control objectives.
