Title: Upper-air meteorological support for ARB's 1995 Mojave Desert ozone transport study.

Principal Investigator / Author(s): Wolfe, Daniel E

Contractor: National Oceanic & Atmospheric Administration

Contract Number: 94-322

Research Program Area: Atmospheric Processes

Topic Areas: Monitoring, Transport


The National Oceanic and Atmospheric Administration's (NOAA) Environmental Technology Laboratory (ETL) System Demonstration and Integration Division was contracted for use of it's newly developed 449 MHz wind profiler / RASS (profiler) in support of the 1995 Mojave Desert Ozone Transport Study. The profiler operated in conjunction with an ozone tidar operated by NOAA's ETL Atmospheric Udar Division. Both systems were located at George Air Force Base and operated for two weeks in early August (near the City of Victorville, California in the Mojave Desert). The profiler continuously monitored the winds from near ground level to a maximum height of 3.5 km above ground level (AGL) and the virtual temperature to a maximum height of 2.5 km AGL. High spatial and temporal resolution wind profiles are available to combine with lidar ozone profiles to calculate ozone flux / transport profiles. Virtual temperature profiles from the RASS are available to help determine the mixing depth. Surface measurements of temperature, relative humidity, pressure and wind speed and direction were also made to supplement the profiler data in the lowest levels.
