Polar stratospheric nitric acid depletion surveyed from a decadal dataset of IASI total columns

Abstract HNO 3 hPa), to monitor the relationship between the temperature decrease and the observed HNO 3 HNO 3 O 3 3 together with temperature (taken from reanalysis at 50 hPa), the recurrence of specific regimes in the annual cycle of IASI HNO 3 hPa temperature (“drop temperature”) corresponding to the onset of strong HNO 3 HNO 3 HNO 3 ± K, close to the nitric acid trihydrate (NAT) existence threshold (∼ K at 50 hPa), is found in the region of potential vorticity lower than - × - 5 K m 2 kg - 1 s - 1 (similar to the 70–90∘  S equivalent latitude region during winter). The spatial distribution and interannual variability of the drop temperature are investigated and discussed. This paper highlights the capability of the IASI sounder to monitor the evolution of polar stratospheric HNO 3 O 3.
