PII: SOO224073(%)001574 SATELLITE MEASUREMENTS OF ATMOSPHERIC OZONE PROFILES, INCLUDING TROPOSPHERIC OZONE, FROM ULTRAVIOLET/VISIBLE MEASUREMENTS IN THE NADIR GEOMETRY: A POTENTIAL METHOD TO RETRIEVE TROPOSPHERIC OZONE

Abstract-Numerical studies of a new method for the retrieval of ozone profile information from nadir-observing satellite measurements in the ultraviolet and visible are presented. The method combines information from back scattered radiation in the Hartley band down to the Or concentration peak, lower atmospheric information from the temperature structure of the Huggins bands, and a constraint on the total column from the Chappuis bands. The Huggins bands ’ temperature structure provides altitude information on the ozone distribution that includes clear distinction between stratospheric and tropospheric ozone. Studies presented here include dependence of the retrieved 0, profiles on surface albedo, tropospheric aerosol, and tropospheric 01 content for a range of atmospheric onditions.
