Purpose of Flight:Science
Comments:Coordinated flight with DC-8. eMAS was known IN-OP prior to flight. All other instruments had good indications. Inmarsat worked the entire flight for ssh logins which was very helpful. Significant science objectives were accomplished today and the aircraft is in good shape.

Mission Summary: 

Flight Report – SEAC4RS ER-2, September 2, 2013 (Science flight #9)

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

Purpose of flight: A flight to study convection over land, in close coordination with the DC-8 and SPEC LearJet.

Take-off:  10:32 local (Central DST) (UTC start = 15:32, UTC end =23:46)

Duration: 8.2 hrs

Notes:  The ER-2 went to a location near Jackson (MS), where pre-frontal convection was expected to develop during the day. Late delivery of revised flight plans to ER-2 pilots in the morning had resulted in only a small delay in the scheduled take-off time. The original ER-2 flight plan was adapted by eliminating the first bow-tie in the extended bow-tie pattern near Jackson. The ER-2 flew four bow-tie patterns, the first of which was closely coordinated with the DC-8. Towards the N of this pattern, the ER-2 remote sensing instruments observed significant Cirrus. Following the bow-tie pattern, we vectored the ER-2 on a generally E-W leg to survey potential targets for Ci outflow from the convective systems sampled by the DC-8 and SPEC LearJet. A parallel leg was then flown in close coordination (generally within 1 minute) with the DC-8 for stacked radiation/in situ comparisons. The ER-2 was then vectored to set up for a straight descent into a Ci outflow region to take in situ measurements. This descent was extended downward to 36kft, after not reaching the Ci at 41kft. Another descent/ascent was flown en route home. Communication between ER-2 flight scientist, ground pilot and pilot was excellent. Overall a successful flight to study SEAC4RS convection-related objectives.


Aircraft and instruments: Communication with instruments via Iridium and INMARSAT was good. eMAS had experienced a cooler problem the day prior to flight and was not operating on this flight. All other instruments appear to have worked nominally. Aircraft ready to go for science flight on Sept. 4, 2013.
