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: This licence has been issued for the scientific research application No.5115. The overall goal of this project is to increase our knowledge of how tundra environments interact with the atmosphere and predict how changing tundra vegetation will affect future climates. Tundra ecosystems exchange energy, water and carbon gases with the atmosphere, which are important elements of the climate system...

Summary: The objective of this wind monitoring proposal is to continue to measure the wind energy potential at CN Hill (approximately 130 km from Yellowknife) until the site is next serviced and the equipment removed. This is part of an alternative energy study for the Yellowknife area. Wind data will be collected using instruments that measure wind speed, direction, and temperature. Sensors are already in...

Summary: The objectives of this survey are to measure patterns of methane (CH4) concentrations over the Mackenzie Delta and to quantify the emissions of CH4 from this area. Together with the data of our previous campaigns we will be able to analyse the interannual variability of methane fluxes. Furthermore, the research team will investigate the possibility of linking in-situ data of tundra landscape ch...

Summary: The objective of this wind monitoring proposal is to continue to measure the wind energy potential at the Inuvik High Point (approximately 6 km northeast of the Inuvik airport). This is part of an alternative energy study for the Inuvik area. Two full years of wind measurements and an economic analysis will be necessary to confirm the wind energy potential at the Inuvik High Point site. The study ...

Summary: The objective of this wind monitoring proposal is to measure the wind energy potential at CN Hill (approximately 130 km from Yellowknife) for two years. This is part of an alternative energy study for the Yellowknife area. Wind data will be collected using instruments that measure wind speed, direction, and temperature. At CN Hill, the sensors will be installed on an existing Northwestel Tower. Tw...

Summary: The objectives of this survey are to establish patterns of methane (CH4) concentration in the atmosphere over the Mackenzie delta region and to quantify the emission of CH4 from these areas. Together with the data from previous data the research team should be able to estimate the annual contribution of the Mackenzie delta region to the atmospheric methane budget. Furthermore the research team wil...

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...

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...
