Installation of a new station in the Total Carbon Column Observing Network in Cambridge Bay, NU

The Total Carbon Column Observing Network (TCCON) is a network of high-resolution Fourier transform infrared (FTIR) spectrometers that retrieve column-averaged dry-air mole fractions of a set of atmospheric species. We have installed a new spectrometer that fits TCCON specifications at the Canadian High Artic Research Station (CHARS), in Cambridge Bay, Nunavut. This is part of the Multidisciplinary Observatory for Arctic Climate Change and Extreme Events Monitoring (MOACC), which will contribute to various networks by collecting data from the Arctic, a sensitive region that is disproportionally affected by the effects of anthropogenic climate change. Cambridge Bay has been a location for consistent meteorological observation since the 1950s, but a comprehensive climatology of the region was identified as a gap in the literature. I present the results of our analysis of existing meteorological data as preparation for the role that the MOACC observatory will play in collecting Arctic data, and provide an overview of the progress to date on the installation specifically of the TCCON-compliant FTIR spectrometer and its preparation to be part of the TCCON network.
