SGP/AERI/C1 - Nest on the input port window
DataStreams:sgpaeriengineerC1.b1, sgpaerich1C1.b1, sgpaerisummaryC1.b1, sgpaerich2C1.b1
Description:
On June 23, 2009, a mud dauber nest was found on the input port window of the AERI 
interferometer and was removed. The nest was likely responsible for significant signal loss.  
The nest was estimated to have covered close to 20 percent of the window. While the 
presence of the nest increases signal loss, the measurement values remain valid despite the 
obstruction. The input port obstruction due to the nest was consistent during calibration 
Black Body measurements as well as during sky measurements. The same may not apply during 
nest building or other insect activity within the instrument field of view.
