Tolnet Ozone and Aerosol Observations during Past Major Campaigns

In addition to providing tropospheric ozone and aerosol profiles for validation of satellite retrievals, a major objective of the Tropospheric Ozone Lidar Network (TOLNet) is to make high spatio-temporal ozone and aerosol observations to support various field campaigns in atmospheric chemistry studies. These profiling measurements can fill the gap between surface monitoring networks and global satellite observations in various dynamic or chemical process studies, model evaluation, and air-quality studies. This presentation will provide an overview of the accomplishments and important findings of TOLNet made during previous campaigns such as SENEX, SEAC4RS, AJAX, DISCOVER-AQ Colorado, CABOTS, FAST-LVOS, SCOOP, OWLETS I and II, LISTOS, and FIREX-AQ. This comprehensive review will also provide a critical assessment of the TOLNet lidar capability and measurement accuracy for more effective use of the TOLNet data.
