1. Characterize the relative abilities of space-based W, Ku-, and Ka-band radars and microwave imagers and sounders to detect light.
What are the detection limits of each instrument? Can rainfall probabilities be assigned to Z and TB signatures?
2. Evaluate retrievals of rainfall intensity in shallow freezing level environments.
How does the ratio of cloud-rain impact PIA and PMW TBs? How does the vertical structure of precipitation impact
emission/attenuation-based algorithms? What are the impacts of other algorithm assumptions including
DSD and melting layer properties on rainrate estimates? How do well are FOV-dependent factors such as beamfilling and
multiple-scattering represented?
3. Determine the properties of the local environment that influence the characteristics of precipitation in this region.

Wyoming King Air W-band cloud radar Water content: DMT, Gerber, Nevzorov Microphysics: 2D-P, CIP, CDP (FSSP/2D-C) Aerosol: PCASP-100X Environment: RH, T, altitude, wind speed
Departing Wyoming ~Sept. 1 (5 days in transit) 3-5 days installation + 4 hours of test flights
(Sept. 8-14) Research flights:
Begin Sept. 15, 2010 Based in Turku – 30 minute transit to Helsinki 50 total research flight hours budgeted (~13-14 flights) End no later than Oct. 20, 2010
Radar quicklooks will be ready within 24 hours of all research flights.
First cut versions of many probe datasets (eg. DSDs, water contents) will also be turned around in 24 hours and stored along with radar data in a netCDF file for each flight segment.

Leg FIR0-FIR15 Plan to fly this path at different altitudes:
FIR0 at 500’ MSL FIR1 at 1000’ MSL FIR2 at 2000’ MSL Similar up to FIR15 at FL150
The FIR Leg will be repeated five times. Either: FIR0, FIR3, FIR5, FIR7, FIR15
*OR* FIR1, FIR4, FIR9, FIR15, FIR4.

5:00 pm Weather briefing/initial decision regarding operations the following day
7:30 am Updated weather/Baltic radar analysis for definition of potential flight tracks
8:00 am Report to ATC with planned tracks and approx. take-off time
TO-1 hour Final check of radar; go/no-go decision TO-0.5 hour Pre-flight briefing with aircraft team (Turku airport) L+0.5 hour Post-flight briefing with aircraft team (Turku airport) L+1 hour Flight/ground-operations tag-up (small group) L+6 hours Daily operations summary posted on website
(weather summary, instrument notes, flight specifics, data quicklooks, etc.)
Three bases of operation: Kumpula campus, Turku airport hangar, and office at Hotel Centro (Turku)
In-flight communications – 2-way radio (source TBD) Initially restricted to pre-defined flight tracks but may
have more flexibility as experiment progresses
Aircraft Tracking: REVEAL box will transmit lat/lon and altitude that can be ingested and plotted with radar software in real-time Ingest being tested now
To keep briefings running smoothly, group discussions should be held in each location independently and relayed to other group via a small number of group leads via Skype/web-meeting
