Tropospheric ozone measurements at a mid-latitude site using the RTD DIAL technique

摘要

Abstract: Ozone concentrations vary considerably in the troposphere on all spatial and temporal scales. The study of tropospheric ozone variability and trends require highly accurate measurements over time scales from minutes to years. The NOAA Rapid Tunable Daylight (RTD) Differential Absorption Lidar (DIAL) system with its high temporal (2 minutes/profile) and spatial (less than or equal to 1 km vertical) resolution is particularly well suited for these studies. The 5 year data set from our mid-latitude site provides valuable information about the processes that contribute to the variability of tropospheric ozone on timescales from minutes to years. !24
