C4 GAP Meeting
May 16, 2003

8:40 a.m. Jay Fein (from NSF) speaks first:
Benefits of UAV for long duration observations

Dr. Ramanathan speaks: Background of GAP, defines Albedo:

Why is Albedo 30% constant? Was it always 30%?
Clouds regulate albedo
Have a cooling effect
Coupling between vegetation and albedo

Brown Clouds – how does brown cloud modify properties?

Asian dust cloud polluting the Pacific Ocean.
Coal (s) and U.S. west coast

Someday wants to fly across Pacific

How did we get here?

Purposed of the meeting today:
· Assess the progress
· Assess the strategy
· Inform NSF
· Propose short term plan

Bill Tragler – Polymer and Materials
· “Imitate Nature”
· Discuss Mimal ingredients
· Intelligent nanosenors
· UCSD, AFRL, SBCCOM supported research.

· Development
· Miniaturization
· Single chip integration

Ivan’s group does magnetic sensing with nanostructures.
Working on IR detection

Trogler group – chemical sensing
? Biosensing

Environmental Sensing

Nanosensors - Molecular Beam Epitaxy
- group can have nano fabrication ( thin film sensors) up and running in 3 months.
- Use real time senor calibration
- Working on sensor networking and wireless communication – should be feasible to relate sensor data back to home.

Effect of Pulsed Discharge
(getting more energy out of a battery)
Done work on protocol of this technique
Showed results of tests on power generated by pulsed discharge battery.
Is keen to bring together interdisciplinary groups to work on a single project to the mutual benefit of all.

9:35 a.m. John Kosmatka
(See notes handout)

Closest planes – Aerosonde (Insitu)
Seascan (Insitu)
Do not have range or payload ability for GAP mission
Cannot purchase these.

Since the Proposal, the plan has changed from two separate (different) planes: PT & FM to new plan where the PT plane will be designed with some engine and similar design so that when we transition to FM, we just make necessary adjustments (change wing/tail shapes, e.g..) for longer range and larger payload.

Must get on to Irridium satellite network in order to have communications over ocean.
power requirements will be the same for PT and FM. Only wings, booms and satellite uplink for remote control will be modified to create FM.

Front 1/3 of fuselage will be for science payload and will have separate designs for each payload configuration that is simply plugged in to swap.

Two Kavan engines will be here by the end of next week.

Tools for laying up the wings and spars will be aluminum and made once – then you can multiply/ produce a large number of planes.

Autopilot will be developed for PT, but extension to satellite communications will only occur if the MRI is funded.

10:25 a.m. Jose Panza

Instrument portion of Fuselage will be easily modified. The skin portion around the instruments will not take any load, so it can be easily modified.

11 a.m. Greg Roberts
