  1. NDACC Huntsville Station Operation NDACC Lidar Working Group Meeting, NASA/JPL, Table Mountain, CA, Nov. 4, 2013 Mike Newchurch1, John Burris2, Wesley Cantrell1, Shi Kuang1 1UAHuntsville, 2NASA/GSFC http://nsstc.uah.edu/atmchem/

  2. Data Status Operational months of the recent two years Total operational days Hardware improvements affecting operations: the experiments/installation of the PBL receiver channel and (2) change of the transmitter from dye laser (285-291nm) to Raman shifted laser (289-299nm). Shi Kuang is working on the data archiving with the new NDACC lidar format. UAH O3 lidar webpage http://nsstc.uah.edu/atmchem/lidar/DIAL_data.html

  3. Major Improvement and Accomplishment Built a 1’’ mini receiver to extend the ozone observations down to ~100m AGL. Upgraded the transmitter from dye lasers to Raman-shifted lasers for a more stable output, quicker initialization, and easier operation. Participated in two important field campaigns led by US federal agencies (NASA, NOAA, EPA) in 2013 summer, SENEX and SEAC4RS, and accumulated significant data for the coming year. Published two peer-reviewed papers in 2012 and 2013: Kuang, S., M. J. Newchurch, J. Burris, L. Wang, K. Knupp, and G. Huang (2012), Stratosphere-to-troposphere transport revealed by ground-based lidar and ozonesonde at a midlatitude site, J. Geophys. Res., 117, D18305, doi:10.1029/2012JD017695. Kuang, S., M. J. Newchurch, J. Burris, and X. Liu (2013), Ground-based lidar for atmospheric boundary layer ozone measurements, Appl. Opt., 52, 3557-3566, http://dx.doi.org/10.1364/AO.52.003557.
