SATELLITE MEASUREMENTS OF ATMOSPHERIC OZONE PROFILES, INCLUDING TROPOSPHERIC OZONE, FROM ULTRAVIOLET VISIBLE MEASUREMENTS IN THE NADIR GEOMETRY - A POTENTIAL METHOD TO RETRIEVE TROPOSPHERIC OZONE/

Numerical studies of a new method for the retrieval of ozone profile i nformation from nadir-observing satellite measurements in the ultravio let and visible are presented. The method combines information from ba ck scattered radiation in the Hartley band down to the O-3 concentrati on peak, lower atmospheric information from the temperature structure of the Huggins bands, and a constraint on the total column from the Ch appuis bands. The Huggins bands' temperature structure provides altitu de information on the ozone distribution that includes clear distincti on between stratospheric and tropospheric ozone. Studies presented her e include dependence of the retrieved O-3 profiles on surface albedo, tropospheric aerosol, and tropospheric O-3 content for a range of atmo spheric conditions.
