  1. MDE Profiler Ft. Meade, Maryland MARAMA Monitoring and Profiler Meeting October 24, 2001 Atlantic Sands Hotel - Rehoboth Beach, DE Maryland Department of the Environment

  2. Profiler Background • LAP-3000 (Lower Atmospheric Profiler) and RASS (Radio Acoustic Sounding System) • Installed in June 1998, operating ever since • Located at Ft. Meade (half-way between Baltimore and Washington, DC • Maintained by MDE

  3. LAP Pulsed Doppler Radar measures wind speed and wind direction using microwaves and the Doppler Effect LAP measures for 25 minutes, twice per hour, 24 hours per day. LAP has two simultaneous modes: High resolution, every 60m up to 1.5km Low resolution, every 160m up to 4km RASS measures Virtual Temperature using relationship of speed of sound to air temperature RASS measures for 5 minutes, twice per hour, 18 hours per day prior to August 7, 2000; edited radarntt.par file to 24 hours per day since August 7, 2000. RASS range of 1km Operating Parameters

  5. Data Logging and Availability • Each morning the previous day’s data is automatically downloaded from the profiler site to a dedicated PC at MDE via ProComm Plus. • The data is QA/QC and copied to an MDE server. • The QA/QC process consists of checking the file sizes. • Data is displayed using LAPGraph Version 2.73. • Data is only posted internally at MDE. • UMCP, PSU, and NOAA have direct dial-up access

  7. Ongoing Research Interests • Low level jet (LLJ) research • Ozone forecasting (checking the current situation) • Ozone episode analysis

  8. Hardware and Software Support • Cost of hardware support • $25K annual service support contract • Current contract good through 9/30/02 • Support consists of phone assistance • Only hardware service was for an amplifier, but at the time service contract had expired • Cost of software support • $10K Y2K fix • Right now no money allocated in the budget for profiler software upgrades

  9. Contacts at Vaisala • Service Contract with Vaisala Meteorological Systems, Inc. (303) 443-2378 www.vaisala.com Radian International, L.L.C. acquired by Meteorological Systems Company, Inc. (MSCI) MSCI subsequently renamed as Vaisala. • Contractual POC: Dan Donahue Woburn, MA (781) 537-1068 dan.donahue@vaisala.com • Operations Manager: Gary Zeigler Boulder, CO (303) 402-4700 gary.zeigler@vaisala.com • Technical Contacts • John Newschafer (303) 402- 4706 • Kevin Hall (303) 402-4708 • George Frederick (PM) (512) 989-4308

  10. Contacts at MDE • Earl Blue (410) 631-3275 eblue@mde.state.md.us • Fran Pluciennik (410) 631-3756 fpluciennik@mde.state.md.us • Matthew Seybold (410) 631-4401 mseybold@mde.state.md.us • Michael Woodman (410) 631-3229 mwoodman@mde.state.md.us Others with Direct Dialup Access • NOAA Leon Benjamin (303) 497-6031 • UMCP Charles Piety (301) 405-7668 piety@atmos.umd.edu • PSU Bill Ryan (814) 865-9025 wfr1@psu.edu

  11. Discussion • Great tool but will be better when used in conjunction with open access to other profiler sites. • Compare MDE’s profiler parameter setup file with other profiler sites (radar.par) • Currently using the profiler default setup created at the time of installation by Radian

  12. Discussion (continued) • To get the most use out of the profiler • Training? • At MDE no money in budget to update profiler software • Any grant money available? • How to make data more accessible to all • Secure FTP Site?
