Abstract:
We investigate the diurnal variation of PBL ozone at the Boulder Atmospheric Observatory (BAO) in July 2014 using multiple observations, including three ozone DIALs, several wind Doppler lidars, free-launched and tethered ozonesondes, and in-situ measurements on the BAO tower. Three mobile lidars from the Tropospheric Ozone Lidar NETwork (TOLNET) provide high spatial and temporal ozone profiles from near surface to the top of the troposphere. The combination of multiple observations will provide detailed structure of the diurnal variation of ozone. This ozone information will help the satellite and modeling communities to study the character of lower tropospheric ozone for the improvements of satellite retrieval and air-quality models. In addition, a Large-Eddy Simulation model will calculate ozone in the mixed layer to explain the processes responsible for the observations.
