Tropospheric Ozone

J. T. Sullivan (GSFC), L. Twigg (SSAI), and G. Sumnicht (SSAI) – Tropospheric ozone DIAL system operational since 2014, mostly during NASA campaigns at various locations. Measurements are from 0.2 – 12 km during daytime and extend to near 14 km at night.

V. Duflot (U. de la Réunion) — Tropospheric ozone DIAL system began making measurements in February 2013 in preparation for NDACC certification. Ozone profiles are routinely obtained from 6-19 km.  Participated in Maido Lidar Calibration Campaigns in April 2013 and November 2013 and in the Maido Observatory Gas and Aerosols NDACC Experiment in May 2015. Instrument certified for NDACC affiliation February 2017.  Measurements pause in February 2024 due to departure of PI.  Replacement being sought.

T. Leblanc (JPL) — Tropospheric ozone system operational since November 1999. Data up to Dec. 2013 archived under previous PI (McDermid).

M. Newchurch and S. Kuang (U. Alabama, Huntsville) — Tropospheric ozone DIAL system operational since 2008. Measurements are from 1 – 12 km daytime and nighttime.  A low altitude channel (0.1 – 2 km) was added in February 2013. Addition of 2-axis hemispheric scanner in 2017, e.g. for horizontal measurements. System to be integrated into a truck for mobile deployments.

G. Ancellet (LATMOS-IPSL) — Began NDACC operations in January 1991. Database extends back to 1989. New lidar system installed in March 2012 (Licel electronic boards). Participated in Aug. 1989, March 1991 intercomparison with aircraft and ozonesondes and in 2017/2018 intercomparison with GSFC mobile lidar and ozonesondes.
