Description:	A problem was found with the new AERI in the optical trailer at the central facility. The climate controlled air from inside the optical trailer was penetrating into the AERI front-end under certain conditions, thereby contaminating the measurements in the atmospheric layer nearest the surface. Some cases have been found where the AERI-01 (adjacent to the new AERI) also showed this contamination. The symptoms are a ~15 min oscillation in observed radiance that correlates with the temperature inside the optical trailer. Note that data averaged over periods >~15 mins will be minimally affected.
Suggestions:	The mentor team is developing an algorithm to identify the cases where this problem occurred. The signature is a correlation between the temperature inside the optical trailer (e.g. SCEtemp) and the temperature in the front-end (e.g. BBsupportStructureTemp)
