  2. Science Goals • 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? • 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? • Determine the properties of the local environment that influence the characteristics of precipitation in this region.

  4. Aircraft Operations • 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

  5. Data Z • 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. DSD/PSD RH and LWP T and z

  6. Quicklook Examples

  7. Fight Tracks: Leg FIR • 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.

  8. FIR Legs Kerava Radar FIR Leg: FIR0-FIR15 Pt. 1 Kumpula Radar Pt. 2 FIR Leg: FIR0-FIR15 Pt. 4 Pt. 3

  9. RHI Tracks • Along axis of ground research radars • 4 legs at different altitudes that depending on weather conditions. The lowest altitude will be 1000 ft. above highest terrain/obstacle as dictated by controlling authority. • ~60 Kilometer Tracks: • Jarvenpaa, Mansala, and Porvoo (with KER RHIs) • ~30 – 40 Kilometer Tracks: • Kumpula and Emasalo (with KUM RHIs)

  10. RHI Tracks Pt. 13 Track: Mansala 2-15 Pt. 15 Track: Jarvenpaa 2-15 Pt. 12 Pt. 14 Pt. 11 Pt. 10 Track: Kumpula 0-15 Track: Porvoo 2-15 Kerava Radar Pt. 6 Track: Kumpula 0-15 Track: Emasalo 0-15 Kumpula Radar Pt. 8 Pt. 1 Pt. 9 Pt. 5 Pt. 6 Pt: 4 Pt: 3

  11. Spirals • Spiral descent: • 500 fpm descent rate • 1 minute legs • standard rate turns • from FL 150 to 1000’ AGL (500’ over water) • Option: can do small race-tracks or continuous descents

  12. Spirals over Ground Sites Pt. 16 Spiral: S5 Spiral: S3 Kerava Radar Pt. 8b Pt. 1 Kumpula Radar Spiral: S2 Spiral: S1 Pt. 2 Pt. 7 Spiral: S4 Pt. 4 Pt. 3

  13. Daily Briefing Schedule • 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)

  14. Coordination • 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
