Aircraft Flight Summary
Flight Track Map
This was the eleventh flight, out of Homestead Air Force Base, Florida and transit to Wallops Flight Facility. Science goals include:
1. SIMPL/DBASR lines during transit (Everglades, Florida).
2. CAR BRDF measurements
P-3B Instrument Payload:
CAR - Cloud Absorption Radiometer measured angular distribution of scattered radiation and acquired BRDF measurements over the Everglades. Full operational the entire flight.
SIMPL: no instrument report, but was fully operational. Dave Harding, Phil Dabney operated the instrument.
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 2033 on September 14, 2011 out of Homestead Airforce base, Florida and transit to Wallops Flight Facility, Virginia. Observations by CAR operator, Rajesh Poudyal.
