Abstract

The application of UV lidar to measure isoprene concentrations for environmental studies has been investigated. With a hard target lidar system at 223   nm , isoprene mixing ratios above eucalyptus trees were measured with a sensitivity of about 1 ppbv. Results over a long timescale were compared with an existing model of isoprene emission for a wide range of temperature and sunlight values. Fast time dependent results yielded a leaf emission rate of 25   μg   g 1 hour 1 , consistent with emission from other eucalyptus species. Requirements for development of the system for range resolved isoprene number density measurements using atmospheric backscatter lidar are discussed.
