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

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?

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

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)
