Aircraft Flight Summary
Flight Track Map
This was the tenth flight, out of Homestead Air Force Base, Florida. Science goals include:
1. SIMPL/DBASR lines over the Everglades, Florida.
2. CAR cloud 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 13, 2011 out of Homestead Airforce base, Florida. Observations by CAR operator, Rajesh Poudyal.
