Flight Plans – in development Mission type Mission details Aircraft and roles Cross Section Missions (see also Figs. X.3) 5 – 6 flights for C-130 (~50 research hours) 9 hour duration (C-130) 10 min legs (below, in and above clouds, approx. 12 each) Profiles up to 4km Night missions: Take–off: 3-4 am; Land: noon-1pm (local time) Flight track: along 20°S (transit from Arica to 72W, 20S then along 20S to 82-85W) Each C-130 flight to include RHB Co-sampling (30-40 minutes) C-130 alone BAe-146 alone C-130 and BAe-146 together Dornier may cosample (overfly) during start or end of missions G-1 may cosample during end of mission POC-Drift Missions (see also Fig. X.4) 5 – 6 flights for C-130 (~50 research hours) 9 hour duration (C-130) Take-off: 10 am; Land: 7 pm (local time) Flight track: variable depending upon POC location Chiefly C-130 alone Occasionally BAe-146 or G-1 but separately Stacked cloud/radiation Missions (see also Fig. X.5) Daytime flights only. Flight track: near-coastal zone, horizontal legs between fixed points Chiefly BAe-146 and Dornier 228 G-1 may also participate Coastal zone cloud sampling Missions (see also Figs. X.6) Single-aircraft missions Mostly daytime flights Flight track: Typically horizontal legs and some profiles sampling subcloud, cloud and FT Chiefly G-1 and Twin Otter Some BAe-146 Multi-flight quasi- Lagrangian Mission (see also Fig. X.7) Multi-aircraft (sequentially) Flight track: as for POC-drift mission Aircraft flights spaced by 6-12 hours (requires intense planning) One crossing POC boundary; a possible second mission in polluted near-coastal airmass Twin Otter/G-1 (Flight 1); BAe-146 (Flight 2); C-130 (Flight 3) Test/Inter- comparisons (see also Fig. X.8) 3 – 4 flights (<20 research hours) 4 hour duration Flight track: In near-coastal region, subcloud (side-by-side), in-cloud (sequential), and FT (side- by-side) intercomparison legs Two or more aircraft Cosampling between C- 130 and RHB (as part of Cross-Section Missions)
