Mission Summary: 

Flight Report – SEAC4RS ER-2, August 23, 2013 (Science flight #6)

Prepared by: Jens Redemann (Jens.Redemann-1@nasa.gov)

Purpose of flight: A flight to study boundary layer clouds/chemistry/radiation links in coordination with the DC-8, followed by convection near the Mississippi River Valley in Southern Arkansas.

Take-off:  9:52 local (Central DST) (UTC start = 14:52, UTC end =22:33)

Duration: 7.7 hrs

Notes: Coordination with DC-8 at first rendez-vous point required reducing parts of DC-8 flight plan. Worked a West-East 300km leg extending from a presumed isoprene hot spot to the W of the Mississippi across and beyond the Mississippi, mostly to assess the difference in cloud structures and BL chemistry visible on previous days (both satellite imagery and DC-8 obs). ER-2 flew several legs with DC-8 at different altitudes in the BL, below and above developing Cu clouds. ER-2 then broke off to support coordinated convection work between the DC-8 and SPEC LearJet, just East of Mississippi. ER-2 flew three race track patterns, generally N-S with a high tower developing towards the N end of track. ER-2 then returned to morning point of coordination with DC-8 along the E-W leg for contrasting observations. Plans for flight along a triangle to survey region were abandoned due to difficulty in coordination with DC-8. In-flight coordination with DC-8 worked well, but the planned coordination did not work out properly at times, because changes made by the pilots of the two aircraft could not be synced up. This was due to late delivery of flight plans to pilots. Two lessons learned are: 1) deliver flight plans to pilots at noon the day before flight to allow iterations; 2) avoid coordination between aircraft late in the flight. Communication between ER-2 flight scientist, ground pilot and pilot was excellent. Overall a very successful flight for coordinated cloud-radiation work between ER-2 and DC-8.


Aircraft and instruments: Worst flight for Iridium to date. Very few packages sent down to the instrument groups. All instruments appear to have worked. There appears to be an intermittent problem with an experimenter power panel that will be trouble-shot on Sunday (8/25). Aircraft ready to go for science flight on August 26, 2013.
