Curriculum Vitae:

Brian Kahn

Dr. Brian Kahn is a Research Scientist working closely with the Atmospheric Infrared Sounder (AIRS) group. His research interests include active and passive remote sensing of clouds, temperature, and water vapor, with a specific focus on observing cloud and climate related atmospheric processes leveraging the natural synergy of satellite sensor constellations.
