TOLNet
Tropospheric Ozone Lidar Network

The Tropospheric Ozone Lidar Network (TOLNet) is an interagency initiative involving NASA, NOAA, and USEPA, established in 2012. TOLNet provides high-temporal-resolution measurements of tropospheric ozone profiles to support air quality research and satellite validation. It includes several lidar systems across North America: the JPL Table Mountain Facility (TMF) tropospheric ozone lidar, the NOAA Tunable Optical Profiler for Aerosol and oZone (TOPAZ) lidar, the 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), the City College of New York Tropospheric Ozone Lidar System (NYTOLS), the GSFC TROPospheric OZone (TROPOZ) DIAL, the Langley Mobile Ozone Lidar (LMOL), and the Hampton University Lidar Laboratory. The mobile systems within TOLNet can be deployed in the field to provide collocated ozone measurements alongside balloon and airborne sensors.
