  3. • Puerto Penasco • 3 NCAR ISSs (GPS sounding, UHF profiler, RASS, sfc station); 1 GLASS ISS sounding network designed to determine: – initiation mechanisms, structure, and propagation of surges – mechanisms for diurnal cycle of convection – air-sea exchanges, upper-ocean changes – atmospheric budgets, latent heating profiles over land and ocean • Kino Bay • SMN soundings • • • • Los Mochis Loreto or Santa Rosalia • • S-POL • • • fluxes, upper-ocean

  5. ISS Network 3 ISSs (Integrated Sounding Systems) GPS sounding system UHF wind profiler (winds up to ~ 4 km) RASS (Radio Acoustic Sounding System) (Tv profiles) Surface met station 1 mobile sounding system (GLASS) GPS sounding system Surface met station

  6. Data Processing/Dissemination Plan Real Time • All “preliminary” data on the web • Soundings onto GTS – PIBAL messages are generated – Data available for operational models • Local internet service required • CSU soundings-monitoring/processing/display facility Quality-controlled data (ATD ISS staff) • Six months after project, all data • Consensus profiler winds (30-min intervals) • Exabyte tapes, DVD, or FTP; ASCII or net CDF • Further quality control by JOSS/CSU?

  7. Special Issues Staffing • 10 operators required continuously • Crew change at midpoint recommended 20 operators! • Training required • Local requirements: interpreters (?), safety Siting (to be determined) • 16’  16’ area, unobstructed view of sky for 50’ radius, 8’ above ground • unobstructed fetch, no shadowing Supplies • 130 T-cylinders of helium

  8. Field Coordination Requirements Launch frequency • IOP – 6  daily at 2 southern sites – 2  daily at 2 northern sites • non-IOP – 2  daily at all sites • 24-h notice needed for IOPs (possibly shorter) IOP decisions ( 10 IOPs, averaging 2 days each) • Coordinate with aircraft, radar, other ops • Assign IOPs/optimize resources to satisfy NAME objectives (surges, MCSs, diurnal cycle, easterly waves, upper-level disturbances)
