SEAC4RS
Nav Data Collected: 
Yes
Total Flight Time: 
8.1 hours

Funding Source:Hal Maring - NASA - SMD - ESD Radiation Science Program
Purpose of Flight:Science
Comments:Coordinated ER-2/DC-8 science flight based out of EFD. Objectives were primarily for to fly over smoke in Wyoming. The majority of the flight was flown at 61kft geometric altitude with multiple AirMSPI datalines. WAS and SSFR are doubtful that they obtained good data, all other sensors indicated nominal operation.

Mission Summary: 

Flight Report – SEAC4RS ER-2, August 19, 2013 (Science flight #4)

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

Purpose of flight: An aerosol-radiation oriented flight targeting young smoke in NE Wyoming (with a rosette pattern) and aged smoke Nebraska (with a bow-tie pattern), in close coordination with the DC-8.

Take-off:  10:03 local (Central DST) (UTC start = 15:03, UTC end =23:08)

Duration: 8.1 hrs

Notes: After take-off en route to Wyoming pattern, the ER-2 trailed the DC-8 by only a few minutes. DC-8 reported being in Cirrus for a few minutes; ER-2 flew over that location within a few minutes. Should be good opportunity to compare DC-8 in situ measurements to ER-2 remote sensing. Plan was to survey the vicinity of a potential bow-tie pattern location on the way. Original area for bow-tie pattern looked sub-optimal for smoke. ER-2 proceeded to Wyoming and had an early ETA for rosette pattern. Decided to carry out MMS maneuver at 61kft to sync back up with DC-8. Flew rosette pattern at pre-determined location. AOD reported from the DC-8 was ~0.15 at center of rosette pattern, but up to 0.8 at Northern end, where DC-8 decided to extend its legs to sample smoke in situ. After rosette pattern, we headed towards bow-tie pattern in Nebraska. We decided to move the location Southward to the Kansas-Oklahoma border, where GOES AOD was larger and clouds looked favorable. Coordination with DC-8 worked well. Flew bow-tie pattern, AOD reported from DC-8 variable, again with gradient from 0.2-0.6 in the mid-visible. Two long legs for remote sensing on the way home, as well as ascent to 65kft shortly before landing. Communication between flight scientist, ground pilot and pilot was excellent again.

Aircraft and instruments: Communication issues improving – some time periods of Iridium dropping out. Most instruments appear to have worked nominally as far as limited in-flight and quick-look analyses showed. Problems with WAS pump prevented data acquisition. Some problems with SSFR platform remain. No aircraft issues. Aircraft ready to go for science flight on August 21, 2013.
