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!
