MEASUREMENT OF IODINE MONOXIDE FROM GOME-2

摘要

Reactive halogen species play an important role inrntropospheric chemistry. In particular, iodine oxide (IO)rnis involved in catalytic ozone destruction in therntroposphere, changes in the OH/HO_2 and NO/NO_2rnratios, enhancement of the ozone-depleting brominerncycle, Hg~0 oxidation and new particle formation [1].rnHere, retrieval algorithm and Slant Column Densityrn(SCD) measurements of IO from the GOME-2rninstrument will be presented. The results focus on thernAntarctic region. The values shown are preliminary andrntherefore future steps will also be discussed.
