In this paper we present a study of the ozone hole as observed by the
Infrared 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, in particular during
polar night. 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. Total ozone column from IASI and GOME-2 were found to be in
excellent agreement for this region with a correlation coefficient of 0.97,
for September, October and November 2009. On average IASI 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 difference
between both ozone profile measurements being less than ±30% over
the altitude range of 0–40 km. The vertical structure of the ozone profile
inside the ozone hole is captured remarkably well by IASI. |
