MILESTONE CSD01.4:<br />
Develop ship-based <strong>and</strong> aircraft-based lidar systems to measure ozone <strong>and</strong> aerosol profiles.<br />
ACCOMPLISHMENTS FOR CSD01.4:<br />
Two lidars were deployed during the 2006 Texas Air Quality Study (TexAQS II) to measure ozone <strong>and</strong> aerosol<br />
profiles. The TOPAZ airborne ozone-profiling lidar was built the previous year <strong>and</strong> saw its first deployment at<br />
TexAQS II. TOPAZ is a compact <strong>and</strong> lightweight airborne ozone lidar based on an innovative, all solid-state,<br />
wavelength-tunable UV laser transmitter. During TexAQS II, TOPAZ flew 22 missions totaling approximately 120<br />
hours aboard a NOAA Twin Otter airplane during which it mapped out the three-dimensional distribution of ozone<br />
<strong>and</strong> aerosols over eastern Texas <strong>and</strong> the Gulf of Mexico. In addition to ozone mixing ratio <strong>and</strong> aerosol backscatter<br />
profiles, TOPAZ also provided highly resolved information on the spatial distribution of mixed layer height. First<br />
