TOLNet
Tropospheric Ozone Lidar Network

The Tropospheric Ozone Lidar Network (TOLNet) is an interagency initiative involving NASA, NOAA, and USEPA that began in 2012. TOLNet provides highly time-resolved measurements of tropospheric ozone profiles to support air quality research and satellite validation. It includes several lidar systems across North America: JPL Table Mountain Facility (TMF) tropospheric ozone lidar, NOAA Tunable Optical Profiler for Aerosol and oZone (TOPAZ) lidar, University of Alabama in Huntsville Rocket City Ozone Quality Evaluation in the Troposphere (RO3QET), Environment and Climate Change Canada’s Autonomous Mobile Ozone LIDAR Instrument for Tropospheric Experiments (AMOLITE), City College of New York Tropospheric Ozone Lidar System (NYTOLS), GSFC TROPospheric OZone (TROPOZ) DIAL, Langley Mobile Ozone Lidar (LMOL), and Hampton University Lidar Laboratory. The mobile systems within TOLNet can be deployed in the field to provide collocated measurements of ozone alongside balloon and airborne sensors.
