The NASA Langley Mobile Ozone Lidar System: Status, Example Data, and Future Plans

The NASA’s Langley Mobile Ozone Lidar (LMOL) system measures tropospheric ozone and aerosol profiles, and is one of six ozone lidars across the US and Canada participating in the Tropospheric Ozone Lidar Network (TOLNet).  Recent upgrades to the system include a new pump laser that has tripled the transmission output power extending measurements up to 8 km in altitude.   In addition, software and algorithm developments have improved data output quality and enabled a real-time ozone displays.    In 2016, a number of ozone features were captured by LMOL, including the dynamics of an early-season ozone exceedance that impacted the Hampton Roads, VA region with high boundary layer ozone correlated with wind direction.   In this presentation, we will review current LMOL capabilities, recent ozone air quality events observed by the system, and discuss future plans.
