Tropospheric Ozone Lidar Network
Tropospheric Ozone Lidar Network (TOLNet), currently comprising six lidars (4 mobile systems and 2 fixed base systems), is an interagency initiative started by NASA, NOAA, and EPA in 2011. The TOLNet lidar sites make ozone and aerosol high-resolution spatio-temporal measurements through a network of ground sites which are located at NASA Goddard Space Flight Center (38.992°N, 76.839°W), Jet Propulsion Laboratory (34.43°N, 117.67°W), and Langley Research Center (37.096°N, 76.385°W), NOAA Earth Science Research Laboratory (39.995°N, 105.263°W), Toronto, Canada (44.232°N, 79.781°W), and University of Alabama, Huntsville (34.725°N, 86.645°W). Since 2011, TOLNet has been providing observational data products of tropospheric (surface to tropopause) ozone and aerosol vertical profiles to address fundamental air-quality science questions in cooperation with national, state, and local organizations and to support airborne field studies and satellite missions. TOLNet also develops recommendations for more robust, cost effective lidar systems to enable more widespread use. In addition to the vertical profile data, surface ozone measurement data are available at some TOLNet sites.
