Expanding a Ground-Based Remote Sensing Network in the Canadian High Arctic

Ground-based remote sensing networks are essential for validating both models and satellites. The Arctic in particular is a region of much interest due to the disproportionate impact of anthropogenic climate change it is experiencing. The Total Carbon Column Observing Network (TCCON) is a network of near-infrared ground-based spectrometers that retrieve column-averaged dry air mole fractions of CO2, CH4, CO, and other trace gases. It has been used for over a decade The Canadian High Arctic currently contains one TCCON station, at the Polar Environment Atmospheric Research Lab (PEARL) in Eureka, Nunavut. Another location is planned for installation on the Canadian High Arctic Research Station (CHARS) campus in Cambridge Bay, Nunavut. We have begun a climatological review of the site to determine what number of measurement days per year can be expected once the planned site is operational, and preliminary results will be presented.
