“…The accuracy of the system has been discussed in previous studies and Lidar measurement precision is estimated to be ±10% in the lower troposphere and ±20% in the upper troposphere [15,16]. Data from the UAH TOLNet lidar system is publically available [14] and has been used to examine atmospheric chemistry relevant topics such as air pollution transport, nocturnal O 3 enhancements, stratosphere-troposphere exchange, boundary layer pollution entrainment, wildfire impacts on O 3 , and lightning NO x generated O 3 (e.g., [17][18][19]).…”

This study evaluates source attribution of ozone (O 3 ) in the southeast United States (US) within O 3 lamina observed by the University of Alabama in Huntsville (UAH) Tropospheric Ozone Lidar Network (TOLNet) system during June 2013. This research applies surface-level and airborne in situ data and chemical transport model simulations (GEOS-Chem) in order to quantify the impact of North American anthropogenic emissions, wildfires, lightning NO x , and long-range/stratospheric transport on the observed O 3 lamina. During the summer of 2013, two anomalous O 3 layers were observed: (1) a nocturnal near-surface enhancement and (2) a late evening elevated (3-6 km above ground level) O 3 lamina. A "brute force" zeroing method was applied to quantify the impact of individual emission sources and transport pathways on the vertical distribution of O 3 during the two observed lamina. Results show that the nocturnal O 3 enhancement on 12 June 2013 below 3 km was primarily due to wildfire emissions and the fact that daily maximum anthropogenic emission contributions occurred during these night-time hours. During the second case study it was predicted that above average contributions from long-range/stratospheric transport was largely contributing to the O 3 lamina observed between 3 and 6 km on 29 June 2013. Other models, remote-sensing observations, and ground-based/airborne in situ data agree with the source attribution predicted by GEOS-Chem simulations. Overall, this study demonstrates the dynamic atmospheric chemistry occurring in the southeast US and displays the various emission sources and transport processes impacting O 3 enhancements at different vertical levels of the troposphere.

“…Tropospheric ozone DIAL systems have been first developed using tunable dye lasers (Gibson and Thomas, 1975;Pelon and Mégie, 1982;Browell et al, 1983;Proffitt and Langford, 1997;Kuang et al, 2013). Later Stokes lines from stimulated Raman scattering (SRS) of pressurized gas pumped by excimer lasers (Uchino et al, 1983;Kempfer et al, 1994;Eisele et al, 1999) and by Nd:YAG lasers (Ancellet et al, 1989;Sunesson et al, 1994;McDermid et al, 2002;Papayannis et al, 2005;Nakazato et al, 2007;Apituley et al, 2010) were used.…”

“…Their details have been described by Alvarez et al (2011), De Young et al (2017, Langford et al (2011), and Sullivan et al (2015. Some basic procedures were applied on the raw lidar signals before retrievals, such as time integration (5 min for this study), dead-time correction (for PC only), background correction (subtraction), merging of PC and analog signals (for a system with both PC and analog channels), and signalinduced-bias (SIB) correction (Kuang et al, 2013). Some parameters are system dependent or empirical due to different equipment, such as the dead-time value, PC-analog timing offset, averaging range for background calculation, and SIB function form.…”

Abstract. The Tropospheric Ozone Lidar Network (TOLNet) is a unique network of lidar systems that measure highresolution atmospheric profiles of ozone. The accurate characterization of these lidars is necessary to determine the uniformity of the network calibration. From July to August 2014, three lidars, the TROPospheric OZone (TROPOZ) lidar, the Tunable Optical Profiler for Aerosol and oZone (TOPAZ) lidar, and the Langley Mobile Ozone Lidar (LMOL), of TOLNet participated in the Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality (DISCOVER-AQ) mission and the Front Range Air Pollution and Photochemistry Éxperiment (FRAPPÉ) to measure ozone variations from the boundary layer to the top of the troposphere. This study presents the analysis of the intercomparison between the TROPOZ, TOPAZ, and LMOL lidars, along with comparisons between the lidars and other in situ ozone instruments including ozonesondes and a P-3B airborne chemiluminescence sensor. The TOLNet lidars measured vertical ozone structures with an accuracy generally better than ±15 % within the troposphere. Larger differences occur at some individual altitudes in both the near-field and far-field range of the lidar systems, largely as expected. In terms of column average, the TOLNet lidars measured ozone with an accuracy better than ±5 % for both the intercomparison between the lidars and between the lidars and other instruments. These results indicate that these three TOLNet lidars are suitable for use in air quality, satellite validation, and ozone modeling efforts.
