Aircraft Flight Summary
Flight Track Map
This was the third flight operating out of Wallops Flight Facility (WFF) in Virginia. Science goals include:
1. SIMPL/DBASR around WFF.
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. Fully operational the entire flight.
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.
