Summary<br />
IO retrieval from SCIAMACHY<br />
• Multi year data set of IO columns (up <strong>to</strong> 2003 - 2010)<br />
• Conversion of IO slant columns <strong>to</strong> vertical columns<br />
IO above <strong>Sea</strong> <strong>Ice</strong> / Polar Regions<br />
• Strong detailed spatial <strong>and</strong> temporal variation<br />
• Striking differences in comparison <strong>to</strong> BrO<br />
• Enhanced IO above sea ice in late spring time<br />
• Link between IO enhancement <strong>and</strong> reduced ice concentration (still within <strong>the</strong> sea<br />
ice area, relation <strong>to</strong> phy<strong>to</strong>plank<strong>to</strong>n habitat, importance of ice temperature?)<br />
IO <strong>and</strong> Chlorophyll-a / Oceanic Regions<br />
• Some regions with correlation between IO <strong>and</strong> Chl-a, o<strong>the</strong>r regions with no relation<br />
• Importance of specific types of phy<strong>to</strong>plank<strong>to</strong>n is possible<br />
