Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5624. The main goal of this research is to better understand how greenhouse gas emissions from rivers will impact the future trajectory of atmospheric carbon dioxide (CO2) and methane (CH4) concentrations. The research team has identified two key research objectives that will allow them to address major research gaps i...

Summary: The objective of this wind monitoring proposal is to measure the wind energy potential at the Inuvik High Point (approximately 6 km northeast of the Inuvik airport) for two years. This is part of an alternative energy study for the Inuvik area. Wind data will be collected using instruments on a wind tower that will be installed at the site. Two full years of wind measurements and an economic analy...

Summary: The NETCARE observations will be covered the range from Longyearbyen, Svalbard (European Arctic) until Inuvik (NWT – Polar 6 aircraft only) and Barrow (Alaska – Polar 5 aircraft only). The observational platforms will be two aircraft: 1) the Alfred Wegener Institute (AWI) POLAR 5, a modified DC-3 aircraft; and 2) the AWI POLAR 6, also a modified DC-3 aircraft. The two platforms will be coordin...

Licensed Year(s): 2014
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...

Licensed Year(s): 2008
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...

Licensed Year(s): 2007
Summary: The research aims to characterize the physical and chemical properties of forest fire smoke and its impact on the Artic. Three aircraft (CT-133 jet, Dehavilland Sea Heron and Dehavilland Twin Otter) based out of Yellowknife, equipped with standard scientific atmospheric chemistry sampling instrumentation, will be used to sample smoke while airborne. Sampling will take place opportunistically as fi...

Licensed Year(s): 1998
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,...

Principal Investigator: Orr, Dwayne
Licensed Year(s): 1995
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...

Licensed Year(s): 1993
Summary: In this study, we will collect air, dust and rain samples on a weekly basis at five Canadian locations during the months of June and July, 1993. Three locations are in the NWT while two locations are in Saskatchewan. The samples will be analyzed in Regina and Edmonton for the presence of certain insecticides, herbicides and PCB's that are known to be transported in the atmosphere....
