Aircraft Flight Summary
Flight Track Map
This was the seventh flight. Flight was out of Bangor Airport, Maine to Quebec, Canada and back. Science goals include:
1. CAR BRDF measurements over Howland forest.
2. SIMPL/DBASR lines in Quebec, Canada.
P-3B Instrument Payload:
CAR - Cloud Absorption Radiometer measured angular distribution of scattered radiation and acquired BRDF measurements over SERC site near Wallops Flight Facility. Operated for a small section of the flight because of instrument problems.
SIMPL: no instrument report, but was fully operational.
SIMPL is an innovative dual-wavelength, polarimetric, photon counting lidar that provides high-resolution information on the physical properties of terrestrial surfaces based on their light scattering signatures.
PDS Project Data System (PDS). No instrument report. Fully operational. Acquired base meteorological and navigational measurements.
DBSAR - No instrument report. Fully operational.
DBSAR: Digital Beamforming SAR (PI Rafael Rincon). DBSAR is a new generation airborne L- Band radar system that provides two- and three-dimensional fine-scale measurements of biomass.
Approximate time in UTC (US east coast time - 4 hours). Activities during CAR flight 2030 on August 31, 2011 out of Bangor airport, Maine. Observations by CAR operator/PI, Charles Gatebe.
