Description:
Observations at Thule, Greenland, that made use of direct light from the moon on 2,3, 4,5, and 7 February 1988 revealed nighttime chlorine dioxide (OClO) abundances that were less than those obtained in Antarctica by about a factor of 5, but that exceeded model predictions based on homogeneous (gas-phase) photochemistry by about a factor of 10. The observed time scale for the formation of OClO after sunset strongly supports the current understanding of the diurnal chemistry of OClO. These data suggest that heterogeneous (surface) reactions due to polar stratospheric clouds can occur in the Arctic, providing a mechanism for possible Arctic ozone depletion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Solomon, S -- Mount, G H -- Sanders, R W -- Jakoubek, R O -- Schmeltekopf, A L -- New York, N.Y. -- Science. 1988 Oct 28;242(4878):550-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17815894" target="_blank"〉PubMed〈/a〉
