Gas has little influence on the air we breathe; Strong winds can carry it however
down, where it can significantly affect air quality. Carbon monoxide
plays a role in both air pollution and climate change.
In conjunction with the Advanced Microwave Sounding Unit (AMSU), emitted signals are detected
