Flight Summary Report
Author: Dr. Michael King
Mission Scientist: Dr. Michael King
ER-2 Pilot: Jim Barrilleaux
Takeoff: 1940 (UTC)
Landing: 0140 (UTC)
Duration: 6:00 (h:mm)
Objective and Summary:
- Overfly surface sites at Barrow (71°19.37'N, 156°34.9'W) and the SHEBA ice
station (76°18.7'N, 166°7.1'W), then to fly a repeated E-W and N-S cross
pattern over SHEBA.
- The mission was coordinated with the C-130Q at 2300 (solar noon), with the ER-2
flying North over the SHEBA ice station while the C-130Q was within the
mid-tropospheric cloud layer for 50km on a Southbound leg.
- C-130Q aircraft (2300 UTC)
- F-14 satellite (2145 and 2326 UTC)
- NOAA-14 satellite (2207 UTC)
- Solar noon (2300 UTC)
Key Flight Legs:
- The ER-2 overflew the SHEBA ice station (point 1) during an E-W grid from point
2 (76°18.7'N, 167°45'W) to/from point 3 (76°10'N, 157°W) that consisted of 2
flight legs 284km in length, followed by a N-S grid from point 4 (74°18.7'N,
166°7.1'W) to/from point 5 (77°12.7'N, 166°7.1'W) that consisted of 2.4 flight
legs 285km in length. These flight tracks passed over the SHEBA ice station at
2137, 2222, 2234.5, 2259, and 2322 UTC.
- The AirMISR was turned on for 5 acquisitions: twice over the Barrow ARM site
(enroute and return) and 3 acquisitions over the SHEBA ice station. The AirMISR
operated at the following times with notes of observed clouds as seen by
- 2042.5-2057 UTC (ARM)
- 2216.5-2230 UTC (SHEBA)
- 2253.5-2306.5 UTC (SHEBA)
- 2316.25-2331.25 UTC (SHEBA)
- 0009.75-0026 UTC (ARM)
- The ER-2 pilot reported 98% low cloud cover (undercast) starting approximately
200nm North of Fairbanks. Very few breaks in the clouds were observed.
- A multilayer cloud system consisting of low stratus, mid-level altocumulus
(3-4.5km) and upper level cirrus (7.25-8km) reported at the SHEBA ice station.
- A dry layer was seen in the sounding from the ice station between 900 - 650mb.
- The satellite imagery showed a low level cloud to the South of SHEBA and a
multi-layer cloud at SHEBA at 1415 UTC, with temperature inversions at 0.5,
3.2, and 4.2km. Winds were from 65° (ENE) at a speed of 21kts.
- AirMISR (Airborne Multi-angle Imaging Spectroradiometer): No aft camera viewing
(C and D camera positions) and log files not written
- AMPR (Advanced Microwave Precipitation Radiometer): Worked well
- CLS (Cloud Lidar System): Lidar worked properly, but navigation data not recorded
- HIS (High-resolution Interferometer Sounder): Worked from take-off to near SHEBA
the first overpass (~1.5 hr) and then failed; cause not determined
- MAS (MODIS Airborne Simulator): Port 4 bands (8.3-14.0 µm) noisy and
unsatisfactory; will be taken off MAS for next 5 days to purge with nitrogen
- MIR (Millimeter-wave Imaging Radiometer): Worked well
- SSFR (Solar Spectral Flux Radiometer): Worked well
