Short summary

Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) measurements have been analysed to measure the vertical distribution of phosgene (COCl₂) in the UTLS using new spectroscopic data. To highlight its seasonal and latitudinal variability, MIPAS measurements of 2 days/month during 2008 have been analysed. The results show a strong latitudinal variability of COCl₂ with the largest VMR values observed in the tropical regions. The seasonality is fairly low, apart from the polar regions.
