SGP/AERI/C1 - Radiance contaminated from optical trailer air

Under certain conditions, the observed atmospheric radiance at the lowest level (near the 
surface) is contaminated by air from inside the optical trailer. This is a result of an 
inadequate seal between the AERI front-end (outside) and back-end (inside the optical 
trailer), which let inside air penetrate into the first ~1 m of the AERI optical path.  This 
primarily affects the 540-700 cm-1 region, and retrievals and temperature and water 
vapor.  The result is an artifact in the amplitude of the atmospheric radiance that closely 
mirrors the temperature fluctuations inside the optical trailer, specifically oscillations 
with a period of 10-15 mins.
