Assessing the Small Mobile Ozone Lidar (SMOL) Performance Based on 2024 Field Deployments

Ozone profile measurements at high temporal and vertical resolution are needed to better understand physical processes driving tropospheric ozone variability, validate the tropospheric ozone measurements from spaceborne missions such as TEMPO (Tropospheric Emissions: Monitoring Pollution), and evaluate the performance of alternative measurement techniques. As part of the Tropospheric Ozone Lidar Network (TOLNet) efforts allocated to provide such measurements, and leveraging on the experience of more than 20 years of ozone lidar measurements at Table Mountain Facility, the JPL lidar group developed the SMOL (Small Mobile Ozone Lidar), an affordable differential absorption lidar (DIAL) system covering all altitudes from 150 m to 10 km a.g.l. In this presentation, we will review the main characteristics of SMOL and assess its capabilities and performance based on recent deployments during the CINIDI-3 (Cabauw, Netherlands) and USOS (Salt Lake City, US) field campaigns. Upcoming deployments and potential instrumental upgrades will also be discussed.
