FTIR Measurements during the Class of 2004, Mar 24

Class participants looking at the FTIR and hearing about the emissions from various gases at various altitudes in the atmosphere. (Hazem took the photo, and Serena is out of the frame.)

Atmospheric sounding from near the time of the class measurements. (Pretty dry at low levels).

Measurement of downwelling IR, along with calculated brightness temperature. Thin cirrus were present, turning almost subvisual at the time of this measurement.

Halo observed at the beginning of the measurements. Photos by student Hazem.
