Short summary
We present comparison of ozone profiles from DIAL, MLS, and chemical transport model simulations over Río Gallegos (52° S), Argentina, during the 2009 spring. Measurements were performed in the vicinity of the polar vortex and inside it on some occasions. The results show a good agreement between DIAL and MLS with mean differences of ±0.1 ppmv between 6 hPa and 56 hPa. MIROC-CTM also agrees with DIAL, with mean differences of ±0.3 ppmv between 10 hPa and 56 hPa.
