VORTEX2 2009: VORTEX2 will be conducted between 10 May - 13 June 2009 in the Great Plains. It will use an unprecedented fleet of cutting edge instruments to literally surround tornadoes and the supercell thunderstorms that form them. An armada of 10 mobile radars, including the Doppler On Wheels (DOW) from the Center for Severe Weather Research (CSWR), SMART-Radars from the University of Oklahoma, the NOXP radar from the National Severe Storms Laboratory (NSSL), radars from the University of Massachusetts, the Office of Naval Research and Texas Tech University (TTU), 10 mobile mesonet instrumented vehicles from NSSL and CSWR, 38 deployable instruments including Sticknets (TTU), Tornado-Pods (CSWR), 4 disdrometers (University of Colorado (CU) and U of Illinois), weather balloon launching vans (NSSL, NCAR and SUNY-Oswego), unmanned aircraft (CU), damage survey teams (CSWR, Lyndon State College, NCAR), and photogrammetry teams (Lyndon State Univesity and NCAR), and other instruments.

Hurricane Ike 2008: CU-ATOC students and the Center for Severe Weather Research team intercepted hurricane Ike, deploying to the landfall point in Galveston, Texas. The CSWR-Doppler on Wheels (DOW) was deployed in eastern Galveston, 10 wind measuring platforms were distributed on the eastern Galveston seawall, the Galveston causeway, and the Texas City seawall, two mobile mesonet vehicles, each deploying a disdrometer were deployed at either ends of the Galveston causeway. The DOW collected many hours of data over the ultra-fine scale surface array. The center of the eye passed nearly exactly over the east Galveston surface array and the mobile vehilces. DOW radar data from inside the eye reveal mesovortices rotating around the eye, likely enhancing winds and damage in the areas they cross. The mesovortices likely crossed over the fine-scale surface arrays, so high resolution (50 m gating) and surface data will be compared. Crew who weathered the hurricane in Galveston were extracted safely and are on their way home.

Radar Observations of Torndoes and Thunderstorm Experiment (ROTATE) 2008: ROTATE employs the Doppler On Wheels (DOW) mobile radar operated by the Center for Severe Weather Research , mobile mesonet stations, and mobile drop-size and fall velocity disdrometers to observe the kinematic and thermodynamic process of tornado formation, tornado structure, tornado lifecycle, and tornado death. Major goals are to collect observations that will enable the evaluation of tornadogenesis hypotheses and to continue studies of tornado vortex structure and climatology.
