Abstract. Atmospheric remote sensing from satellites is essential for the long-term, continuous monitoring of the ozone hole and is critical in order to evaluate stratospheric ozone recovery. During the last decade, thermal infra-red (TIR) sensors have demonstrated their enhanced capability in capturing both the spatial and temporal variability of the ozone hole during the polar night, in contrast to instruments measuring in the ultraviolet-visible (UV-vis) range of the spectrum which need sunlight to operate. In this paper we present a study of the ozone hole as observed by the Infra-red Atmospheric Sounding Interferometer (IASI) on-board the MetOp-A European satellite platform from the beginning of data dissemination, August 2008, to the end of December 2010. Here we demonstrate IASI's ability to capture the seasonal characteristics of the ozone hole. We compare IASI ozone total columns and vertical profiles with those of the Global Ozone Monitoring Experiment 2 (GOME-2) (also on-board MetOp-A) and electrochemical concentration cell (ECC) ozone sonde measurements for the ozone hole region and period. The IASI and GOME-2 ozone total columns were found to be in excellent agreement for this region with a correlation coefficient of 0.97, for September, October and November 2009. IASI on average, exhibits a positive bias of approximately 7 % compared to the GOME-2 measurements over the entire ozone hole period. Comparisons between IASI and ozone sonde measurements were also found to be in good agreement with the percentage difference between both ozone profile measurements being less than ±30 % over the altitude range of 0–40 km. The vertical structure of the ozone hole is in particular captured remarkably good by IASI.
