Vertical columns of IO – AMF studies<br />

Influencing parameters (examples):<br />

• Ground reflectance<br />

• Solar Zenith Angle<br />

• Absorber altitude profile<br />

• Aerosol scenario<br />

Results from sensitivity studies<br />

� Sensitivity for IO detection much better above<br />

bright surfaces<br />

� Dependency on altitude profile small for bright<br />

surfaces, larger for dark surfaces<br />

� Influence from aerosol amount smaller above<br />

bright surfaces<br />

� More detailed AMF studies including aerosoles<br />

<strong>and</strong> measured IO altitude profiles necessary<br />
