Cost-effective dropsonde observations of wind, temperature, and humidity to fill critical gaps in coverage over oceanic and remote artic and continental regions over days to weeks.
Driftsonde Concept
• Support of the THORPEX International Science and Implementation Plans for demonstration tests of new technologies for the delivery of in-situ sensing • The tests were supported by CNES for the ballooning (French Space Agency)• Support within the US by NCAR and NOAA/THORPEX for the driftsonde gondola and new dropsondes• 8 Balloon flights• 24 to 40 Miniture Dropsondes per balloon flight• Launch Location Zinder, Niger• Flight Operations Center Paris and Boulder• Engineering team effort between CNES & NCAR• Flights 10+ days• CNES Developed Super Pressure Balloon and Flight Control System• NCAR Developed Driftsonde Gondola System, Miniture Dropsonde and Ground Sounding Software
AMMA Driftsonde Project Goals & Highlights
French/CNES Ballooning Group• Developing a 12 meter super- pressure Balloon specifically for Driftsonde.• Provided 10 balloons• CNES gondola for communications, tracking, safety and recovery system, transponder• Prepared launch facility logistics & provided staff at Zinder, Niger • Control & operations center in Paris • Coordinated with Air Traffic Control
• Satellite Communications• Sounding system• GPS tracking info
• 270 MIST Sondes• Ground support crew in Zinder, Niger• NCAR staff at at the CNES control and operations center in Paris.• Secondary Operations Center in Boulder• System control of sonde releases• Sonde data post processing
