Dropsonde Achievements
• First operations with Ku communications:
Download raw D-files from AV-6 in flight
Real-time ASPEN processing
Near real-time posting of skew-T plot to MTS
Near real-time transmission to GTS
Reference to HS3 sonde data in NHC forecast discussions for Nadine
• Plans for parallel GFS model runs• Dropsonde deployment flexibility in various Atlantic
FIRs (e.g., box module insertion in real time)

AVAPS Lessons LearnedFlight Ops
1 – Two AVAPS team members required in the PMOF:
Dedicated drop operator necessary because of intensive comms
AVAPS science seat coordinates drop pattern and any changes with mission scientists and shuttles data to processing team
2 – Additional team required for real-time processing
Instrument Issues
1 - Parachute cap manufacturing anomaly being addressed
2 – RF noise interference issue is under investigation

Science Directions• Tropical-extratropical transition: trough interactions• Aerosol-cloud-precipitation interactions: Role of SAL• HS3 science investigations: Build collaborations with
investigator teams that are using the dropsonde data

Sep 26 Nadine Mission
Dry, stable SAL
Dry, stable continental air
Moist core
How could Nadine survive and even flourish in such a dry, stable environment? Is the core within a “protected pouch”? How does convection overcome the stable low-level environment and inversion? Are differences in SST and surface air temperature important to enhance surface fluxes?

• Dropsonde RF Signal Strength vs Time for First 6 dropsHS3 2012: Case 2 – Science Flight #2
Why has the ‘no signal’ noise floor increased on Drops 2 through 6 (shown here) and all subsequent drops?
Drop 1, the ‘Bermuda’ drop
