TOLNet
Tropospheric Ozone Lidar Network

The Tropospheric Ozone Lidar Network (TOLNet) is an interagency initiative among NASA, NOAA, and USEPA starting in 2011. TOLNet provides highly time-resolved measurements of tropospheric ozone profiles that support air quality research and satellite validation. TOLNet consists of six different sensors across the United States: Jet Propulsion Laboratory’s Table Mountain tropospheric Ozone DIfferential Absorption Lidar (JPL-TMO DIAL), NOAA’s Earth System Research Laboratory Tunable Optical Profiler for Aerosol and oZone (TOPAZ), University of Alabama in Huntsville’s Rocket-city Ozone Quality Evaluation in the Troposphere (RO3QET), Goddard Space Flight Center’s TROPospheric OZone-DIfferential Absorption Lidar (TROPOZ DIAL), Langley Research Center’s Langley Mobile Ozone Lidar (LMOL), and Environment and Climate Change Canada’s Autonomous Mobile Ozone LIDAR Instrument for Tropospheric Experiments (AMOLITE). The mobile systems within TOLNet can be deployed in the field to provide collocated measurements of ozone with balloon and airborne sensors.
