1. DoD Center for Geosciences/Atmospheric Research at Colorado State University Annual Review Nov 15-17, 2005 1 Meteosat Second Generation Algorithms for Use at AFWA Objectives: u Develop algorithms using Meteosat Second Generation data for installation at AFWA u When appropriate, utilize channels which are not available on other satellites, thereby extending and improving AFWA capabilities Stanley Q. Kidder, J. Adam Kankiewicz, and Kenneth E. Eis

2. DoD Center for Geosciences/Atmospheric Research at Colorado State University Annual Review Nov 15-17, 2005 2 DoD Relevance Clouds have a significant impact on DoD operations. u CI clouds impact reconnaissance, air-to-air refueling operations, and add error to infrared masint. u Mid-level clouds to fog impact air operations and flight safety as well as air-to-ground operations.
