AirMeth
Principal Investigator: Hartmann, Jörg
Licenced Year(s): 2016 2013 2012
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...


Wind Energy Monitoring at Yellowknife (2015-2017)
Principal Investigator: Trimble, Annika EV
Licenced Year(s): 2016 2015
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...


Wind Energy Monitoring at Inuvik High Point (2015-2017)
Principal Investigator: Trimble, Annika EV
Licenced Year(s): 2016 2015 2015 2014 2013
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...


Airborne Observations in Support of NETCARE
Principal Investigator: Abbatt, Jon
Licenced Year(s): 2015
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...


Aerosol Chemical Composition in the Arctic (ACCA), a subproject to RACEPAC
Principal Investigator: Borrmann, Stephan P
Licenced Year(s): 2014
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...


Radiation – Aerosol – Cloud Experiment in the Arctic Circle (RACEPAC)
Principal Investigator: Ehrlich, André
Licenced 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...


Study on the Vertical Distribution of Ice in Arctic Clouds (VERDI)
Principal Investigator: Bierwirth, Eike A
Licenced Year(s): 2012
Summary: Climate change and sea ice change affects all who live in the north. The aim of this project is to improve understanding of the physical processes in Arctic clouds and their contribution to the current changes in the polar environment, and thereby reducing uncertainties in regional and global model simulations important for future weather and climate prediction. These research activities combin...


Wind Energy Monitoring in Wekweeti: 2010 - 2012
Principal Investigator: Trimble, Annika EV
Licenced Year(s): 2012 2011 2010
Summary: The objective of this wind monitoring project is to quantify Wekweeti’s wind energy resources. The Aurora Research Institute recently completed a desktop study concerning wind energy in Wekweeti. Computer modelling and analysis of data from nearby weather stations indicates that the wind speeds in the community may be strong enough to support the use of wind energy in Wekweeti at the proposed proj...


Exchange of carbon gas fluxes over low arctic tundra
Principal Investigator: Lafleur, Peter M
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2007 2005 2004
Summary: The research team intends to study how important greenhouse gases, carbon dioxide and methane, are exchanged between tundra surfaces and the atmosphere. They will measure these exchanges over various tundra types and relate them to environmental variables such as soil properties and weather, in hopes of understanding more about how future climate change will impact the land surface and how these ...


Sunphotometer measurements at Yellowknife
Principal Investigator: O'Neill, Norm T
Licenced Year(s): 2011 2010 2009
Summary: The objective of this research project is to measure the aerosol optical depth and sky radiance at Yellowknife using an automated, sun-tracking, CIMEL sunphotometer. In this project, measurements of instruments in the network (called AEROCAN which is the Canadian sub-network of the world-wide NASA-led network called AERONET) are performed using a CIMEL sunphotometer / sky radiometer. This instr...
