In preparation of the upcoming TROPOMI/Sentinel-5 Precursor mission, we
have developed a new retrieval algorithm for SO2 vertical columns and
applied this scheme to 10 years of observations by the OMI/Aura
instrument. In Theys et al. (2015) we compare the SO2 column results with
other well established SO2 products from the OMI and IASI sensors, as well
as with correlative ground-based multi-axis DOAS measurements performed in
Xianghe (China). We show that, in comparison with past data products, our
algorithm provides improved performance in capturing weak SO2 sources. This
is in particular demonstrated by the first detection of shipping SO2
emissions in long-term averaged OMI data.
