NEON sortieApril/May 2006

Goal: •Primary: Fly infra-red camera (IIR) for NEON validation, i.e. measure the infra-red signature/contrast RUNWAY vs. GRASS (under various atmospheric conditions)•Secondary: Take photos of a ship & ship wakes with the IR camera

Conditions/Timing:•Clear-Skies + Around Lunchtime (for max. IR contrast)•Up to 3 dedicated flights of 4.5 hours (or more shorter flights)

Key Instrumentation:•IR camera !•Met (RH, T) !•ARIES, Heimann, [SWS]•Aerosol (PCASP, PSAP, Neph)

IIR

Important:

•Wavelength range:   8 – 9.2 microns

•Calibration! (Joss)

•IR video output (about 25 frames/second?!)•Incorporates a spotter camera

•Field of View (FoV):    45, 23 or 11 degrees depending on lens fitted

•Mounted in Large Radiometer Blister (DEIMOS position) view up to 35 deg below the horizontal

Record both!

Take 11!

Fly accordingly!
