A 10'x6' trailer filled with equipment will be added to the existing Iqaluit Meteorological Supersite. Additional equipment will be set up outside the trailer. All equipment will be sampling ambient outdoor air, either passively by collecting absorption spectra directly, or actively by sucking air through an instrument and then exhausting it back into the atmosphere without any alterations or cleaner, with particulate matter removed. With the exception of one system which uses butanol as a solvent, there are no environmental impacts anticipated due to the direct use of the sampling equipment except for additional noise. Since the proposed site is next to the airport runway, the added noise would be negligible.
To mitigate the environmental impact of the butanol instrument, the output will be passed through an activated charcoal scrubber before being exhausted back into the air. The environmental impact of additional temporary structures at the site is negligible when compared to the infrastructure already present.
