Science - AIRS Atmospheric Science: People: Brian Kahn

AIRS
The Atmospheric Infrared Sounder, AIRS, is an instrument whose goal is to support climate research and improved weather forecasting.

JIFRESSE
JIFRESSE is a scientific collaboration between UCLA and JPL to improve understanding and to develop future projections about global climate change for the Southwest US, particularly California.

CloudSat
CloudSat is an experimental satellite that will use radar to study clouds and precipitation from space. CloudSat will fly in orbital formation as part of the A-Train constellation of satellites (Aqua, CloudSat, CALIPSO, PARASOL, and Aura).
