Correcting for interference of Mt. Pinatubo aerosols on DIAL measurements of stratospheric ozone

Creators

Description

Since March 1991 our group has been routinely operating a Differential Absorption Lidar system in Toronto, Canada. The system is based on a XeCl Excimer laser and the main system parameters are reported. In all measurements after July 21, 1991 we have observed aerosol layers in the stratosphere, resulting from the Mt. Pinatubo eruptions around June 15, 1991. These aerosol layers have increased in size since they were first observed and backscatter ratios of more than 5 to 353 nm have been observed. They interfere significantly with any optical ozone measurement. In this paper we will describe our work to quantify the effects of the additional aerosol on differential absorption measurements and the attempt to correct for them
