What’s missing?
General discussion on science and observations.
1800 Close for day
This session will emphasize the need to work out the flight coordination and science goals within the overarching science questions of the project. Ideally, the following questions will be addressed:
Overview of each groups science goals (operational requirements, lead times, …)
Flight coordination (general, mission selection, design, structure)
0830 Aircraft Operations Plan: Science Goals and Expectations Mace
0900-1145: Reports on Science Goals, Operational Requirements and Desired Flight Profiles from Different Groups. Each speaker is given the following charge: Given 1 or 2 science questions that most interest their group, address the following points:
What are the specific measurement objectives for a given science question? What quantities should be measured in a given circumstance?
What aircraft evolutions are necessary to address a specific measurement objective? (e.g., flight pattern such as long level leg, spiral ascent, synergistic profiles, critical instruments, etc.)
Additional requirements for a specific measurement objective (i.e., over MMCR, in dual Doppler lobes, near cloud top, near cloud base, in TTL, below TTL, etc.)
How many repetitions are necessary to make a measurement meaningful?

1205 Charge to Flight Coordination Working Group McFarquhar
The charge to the flight coordination group will be as follows. We want to develop a general model of how we are going to work out the flights. We have the following generic mission types that will address the science objectives:
Down and dirty monsoon convection:
Down and dirty break convection:
Anvil evolution:
Cirrus:
TTL cirrus
Clear sky/cold pool
For each of these answer the following:
minimum mission for each aircraft
minimum mission for this objective
synergistic flight plan to address this set of specific objectives.
takeoff schedule
potential track for each aircraft
contingencies
other issues
PM
1. Flight coordination
(Mace, MacFarquar, Zipser, Starr, Stephens, Newman, Whiteway, Hacker, May, Pilots, …)
2. Surface Obs network – logistics, real time requirements, products
(Tapper, Bradley, Mather, Lehmann, McBride, Atkinson, Christmas…
3 Forecasting and modeling - group- products, activities, trials,
(Chappel, Jakob, Krueger, …
4. Aircraft logistics – to include site visits as required (logistics representatives from each group).
900 am RAAF base meeting

What to do if e.g.
Missing 1 or more aircraft

Notes from early draft:
Day 1.
AM
Overview of Darwin area, lodging, proposed distribution of lab and office space.
Lori Chappel to lead weather overview.
Topics to include:
Climatology of Darwin. Break vs monsoon, frequency of convection summary of satellite and radar statistics. Large scxale interactions (McBride?)
Predictability of convection at T-2 days, T-1 day, T-6 hrs, and T-1 hr for aircraft operations.
Brief discussion on longer term forecasts e.g. influence of active MJO events and the use of Mat Wheeler’s MJO forecasts? This could affect planning for density of flight IOP’s.
This is assuming that the main weather sensitive part of the operations is related to the aircraft – everything else will operate on a routine basis through the experiment. What lead times are required for various platforms?
Description and demonstration of tools available for analysis to include satellite displays, NWP displays, web products and most importantly for flight operations radar display. There will be a need to discuss what additional capability is desired/required for the radar display – e.g. Overlays of aircraft positions and tracks.
What is required to achieve this?
PM
Organsiation protocols for determining missions
Data policy(ies) by group – what data will be made public? ARM has an open policy so all its data and data sources funded by ARM will be available to the community via the ARM archive.
Updates on status : Ground based network (sondes, radars, lidars)
Fluxes
Ship plans
3rd parties (e.g. University scientists bringinginstruments)
Total 2 hrs
Model activity overview (30 min)
A-Train- orbits/over flights (30 min) Implications for missions.
Brief summary of aircraft status, aims (10 min /group).
Tour of forecast office?
Day 2.
AM
Aircraft configuration (1 hr)
Flight planning
Coordination
Joint operation of aircraft
Who calls shots
Command/analysis structure
Comms requirements
What tools are required to manage the aircraft –what gaps?
Air traffic control.
Roles of participating scientists, both in Darwin and remotely. What product set to be available in real time, near real time? Access to data repository.
Science goals to be met by group
Mission plans
PM
Scenarios for flights to include replaying of satellite and radar for at least 2 cases.
Will require replay facilities for satellite, NWP and radar – a combination of web pages and Bureau’s 3D rapic system.
Day 3.
Grand tour of sites?
Airport, Gunn Point, Point Stewart (AWS site), stop and see the jumping crocs?
i.e Do we want a semi-relaxed day with serious visits to facilities but include a recreation component?
Day 4.
AM
Forecast “trial” planning. How, where, by whom? Would seem to need to handle this as an exercise for a few days a week in Jan Feb using web based information. This would include .
Contingency planning.
What to do if e.g.
Missing 1 or more aircraft
Tropical cyclone in general area?

Day 5
Inspections continue.
Some people may not be required for latter part and likewise some people may want to spend some of the early part of the week addressing facilities, housing, spares etc.
