海洋性大気中でのオゾン光化学消滅

Abstract

Photochemical aspects of low ozone levels observed in the marine atmospheric boundary layers are discussed. It is suggested by using photochemical box model that catalytic loss of ozone involving iodine radical of biogenic origin is one of the primary causes of observed levels of ozone. Estimated iodine cycle is so effective that the seasonal variations in ozone in the lower troposphere over the ocean might be quite largely affected by the local sources of oraganic iodine compounds.To test the above hypotheses, observational evidences of anti-correlation relationships in the concentraions between ozone and iodine compounds would be required. It is also important to more investigate organic iodine burden in the natural atmospheres and oceans.
