Project: TOLNet

The Atmospheric Science Data Center (ASDC) has released the data for the Tropospheric Ozone Lidar Network (TOLNet). TOLNet has been operating since 2011, and is an interagency collaboration between NASA, NOAA, and the EPA with the design to perform studies of air quality and atmospheric modeling as well as validation and interpretation of satellite observations. TOLNet is comprised of six Differential Absorption Lidars (DIAL), each of which are unique and have a long history of ozone observation prior to joining the network. The lidars have been deployed to support nearly ten campaigns thus fan, including the Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality (DISCOVER-AQ) mission, the Korea United States Air Quality Study (KORUS-AQ), the Tracking Aerosol Convection ExpeRiment – Air Quality (TRACER-AQ) campaign, the Front Range Air Pollution and Photochemistry Éxperiment (FRAPPÉ), the Long Island Sound Tropospheric Ozone Study (LISTOS), and the Ozone Water–Land Environmental Transition Study (OWLETS).

Additional information can be found on the TOLNet Landing Page.
