Short summary
Short summary
The MOPITT instrument has been measuring atmospheric carbon monoxide (CO) from space since 2000. Its data products are valuable for CO trend analysis. This paper compares products with different spatial resolutions to identify discrepancies in mean CO amounts and detectable trends for coastal grid boxes. It is found that CO amounts and trends differ significantly between data products for a large number of these grid boxes, essentially due to how the coarser-resolution products are created.

Short summary
Short summary
The choice of path length and retroreflector array size in open-path Fourier transform infrared spectroscopy must be made with care. Longer paths increase target gas absorption (lowering detection limits), and larger retroreflector arrays increase the return signal (improving retrieved concentration precision), but there are limitations to both. An optimum array size and path combination exists in each specific observational environment and application, as explored in this work.

Nineteen years of atmospheric composition measurements made at the University of Toronto Atmospheric Observatory (TAO; 43.66° N, 79.40° W; 174 m.a.s.l.) are presented. These are retrieved from Fourier transform infrared (FTIR) solar absorption spectra recorded with a spectrometer from May 2002 to December 2020. The retrievals have been optimized for fourteen species: O3, HCl, HF, HNO3, CH4, C2H6, CO, HCN, N2O, C2H2, H2CO, CH3OH, HCOOH, and NH3.

Short summary
Using 20 years of high-resolution satellite data, we present semi-quantitative evidence that High-Latitude Dust (HLD) sources to the atmosphere are widespread across the "Canadian Arctic Dust Belt". Our results also suggest that there is some increase in the frequency of dustiness with time, consistent with our understanding that HLD emissions are increasing in a warming climate.
