Summary: The objectives of this research project are: (1.) To perform in-situ measurements of number concentrations, optical properties, and chemical composition of atmospheric aerosol particles with sizes between 3 nanometers and 10 micrometers. (2.) Identify aerosols of natural and anthropogenic origin. (3.) Quantify their relative contributions in dependency of particle size. (4.) Evaluate the pot...

Summary: These research activities combine investigations of clouds and atmospheric aerosol in the Beaufort Sea. The main aim of the cloud studies is to improve the understanding of the cloud-related processes in the Arctic atmosphere and to use these measurements to improve the performance of regional and global climate models of the Arctic. To understand cloud processes knowledge on aerosol properties wh...

Summary: The objectives of this study are to quantify the surface-atmosphere methane emissions over large areas, and to analyze the influence of different surface and vegetation characteristics on large area methane emissions (process understanding). The research team proposes to measure methane fluxes between the tundra and the atmosphere by airborne eddy covariance, a micro-meteorological method. Flux...

Summary: The main aim of these weather and air quality studies is to improve the understanding of the processes in the Arctic atmosphere and to use these measurements to improve the performance of regional and global climate models of the Arctic. The aim of the sea ice studies is to obtain a snapshot of ice thickness in a vast region of the Arctic, and to create an inventory of Arctic sea ice volume. Th...

Summary: The objective of this wind monitoring proposal is to quantify wind energy potential for the economic feasibility of building a wind farm in Tuktoyaktuk. This year the proposed project will involve maintaining data collection at the wind monitoring site, as well as data analysis and reporting. The Tuktoyaktuk wind monitor will visit the wind tower site monthly and maintain the monitoring site e...

Summary: The main goal of this project is to better understand how melt ponds evolve, and their influence on absorption/reflection of solar radiation at the sea ice surface. This information will help to predict summer sea ice melt and future Arctic climate. Data will be collected by using instruments mounted on the German research aircraft Polar5. The airbase of Polar5 will be Inuvik. The aircraft will...

Summary: The Circumpolar Flaw Lead (CFL) system study is designed to examine the importance of climate processes in changing the nature of a flaw lead system and the Arctic marine environment in the Northern Hemisphere, and the effect these changes will have on the marine ecosystem, contaminant transport, carbon fluxes, and greenhouse gases. Using the Canadian Research Icebreaker (CCGS Amundsen), the team ...

Summary: Arctic clouds are dominant on average covering 40 to 60% of the skies over the Arctic ocean. They exert a large influence on the radiation balance in the Arctic, where climate change effects are predicted and observed to be largest in the northern hemisphere. The FIRE III field project will use in-situ measurements obtained using instrumental aircraft, in combination with concurrent satellite dta,...

Summary: The purpose of the campaign is twofold. The first is to fly research instrumentation aboard large scale scientific balloons to measure Cosmic Ray particles entering the earth's atmosphere. The second is to conduct a demonstration flight of newly developed long duration balloon systems for the LDB program. The northern latitudes are desired because of favourable geomagnetic influences on particl...
