NEON Trial SortiesMircromix/CEASAR
Goal: •Fly infra-red camera (IIR) for NEON validation•Measure the Infra-red signature/contrast RUNWAY vs. GRASS (under various atmospheric conditions)•(1 or) 2 dedicated flights
Conditions / Timing:•Clear-Skies !!!•Around Lunchtime (for max. IR contrast)
Key Instrumentation:•IIR•Met (RH, T)•Aerosol (PCASP, …)•ARIES

Typical wavelengths/wavelength bands of interest for the various sensors to be covered by NEON are:
•8-12 um (e.g. thermal imagers)•3-5 um (e.g. reconnaissance sensors)•0.4-0.7 um (visible, e.g. TV sensors)•0.5-1.0 (Night Vision Goggles)•1.06 um, 1.40 um (lasers
Thermal contrast + Transmission=
Infra-red signature
NEON IIR
Specification:
•Wavelength range: 8 – 9.2 microns•video output is PAL which is a 256-line image at a 50Hz update rate … =25 frames/second.•Resolution: 320 x 256 pixels•Incorporates a spotter camera•Mounted in Large Radiometer Blister (DEIMOS position) … view up to 35 deg down from horizontal•Field of View (FoV): 45, 23 or 11 degrees depending on lens fitted
