Four Fourier transform spectrometers and the Arctic polar vortex: instrument intercomparison and ACE-FTS validation at Eureka during the IPY springs of 2007 and 2008.

The article discusses a research which compares the measurements of stratospherically important species involved in ozone depletion including hydrogen chloride (HCl) and hydrogen fluoride (HF). Findings reveal that the densities of gases which were measured by Canadian Network for the Detection of Atmospheric Change (CANDAC) are correlated with the Environment Canada Bomem DA8 measurements. It also notes the results of the evaluation made by a satellite-based research group.
