Abstract
Lidar measurements have proven to be very useful during investigations of atmospheric pollution episodes. Measurements were made during the NARSTO-North East Oxidant and Particle Study (NE-OPS) project in an urban environment using the Penn State Lidar Atmospheric Profile Sensor (LAPS) to investigate conditions for meteorological control of the ground level concentrations and population exposure to ozone and aerosol/particulate matter. LAPS has the capability of measuring ozone, water vapor, temperature, optical backscatter, and extinction by utilizing Raman scatter techniques. The analysis of the return scatter in photon counts, in combination with data processing techniques provides useful information of both the horizontal and vertical structure of the atmosphere during a period of time. Lidar measurements during the campaign have for the first time shown the important transport of aged pollution chemistry depicted in time sequence plots. The focus of this paper will be the ozone measurements obtained by the LAPS instrument and how they compare with other ozone measurements.
