Flight Reports began being entered into this system as of 2012 flights. If there were flights flown under an earlier log number the flight reports are not available online.
Today OIB completed the sea ice North Pole Transect mission. This mission is a near-repeat of an OIB flight flown each year since 2013. The purpose of the mission is to measure the thickness gradient of the ice between the pole and Greenland/Ellesmere Island. At the beginning of the line we entered clouds so went to 2000 feet altitude to stay above them for visibility and icing concerns, then descended back to 1500 feet once out of the clouds. We expected more clouds near the pole from imagery and forecast models, but found only optically thin clouds on the northbound leg of the line towards the pole and almost entirely clear skies on the southbound leg away from the pole. The northbound leg followed a CryoSat-2 orbit with a ~3 hour time difference between our data collection and the satellite overpass. Good data was collected under the CryoSat-2 orbit except for the beginning of the line noted earlier.
Troubleshooting of the BESST instrument continued during this flight with an attempt to determine if RFI from the nose weather radar was causing the system to shut down. The radar was turned off after we exited the cloud deck at the beginning of the line and the power was cycled to restart the system. Since the BESST and FLIR instruments share the same power source this led to a several minute gap in the FLIR data, however forward observers in the cockpit indicated no sea ice leads were present during this gap time. However, shortly after take-off the BESST system had shut down and a system boot error had occurred which prevented the collection of further data and determination of the source of the problems.
A ramp pass was also conducted.
Data volumes:
ATM: 27 Gb some window contamination probable later in flight
FLIR: 3.5 Gb
DMS: 111 Gb
Ku-Band Radar: 137 Gb
MCoRDS: 2.5 Tb, opportunistic data over land ice during transit and experimental data over sea ice
Snow Radar: 137 Gb
BESST: (system malfunction caused loss of data collection shortly after take off)
Lost about 30 minutes of data due to clouds, 20 minutes beginning and 10 end
