NSA/AERI/C1 - Blower motor failure

Description:
The blower motor failed on February 9, estimated time 23:00 GMT. The problem was repaired 
on February 10, 23:00 GMT. The blower motor serves two functions. It maintains the 
instrument window enclosure at the outside temperature and blows ice crystals from the 
enclosure. Failure of the motor caused the enclosure temperature to increase by approximately 12K 
(from 255 to 267K). Previous experience in comparing arctic instruments with the blower 
on and off have shown that if ice crystals enter the enclosure, there is a slight 
increase in the 3-5 um (ch 2) spectral intensity. It is unlikely that Ch 1 is affected.

NSA/AERI/C1 - Excessive Noise in C1 AERI data
DataStreams:nsaaerich1C1.b1, nsaaerisummaryC1.b1
Description:
Initially it was believed that the greater noise level in AERI C1 data was due to the 
extended range detector, which has lower sensitivity. However, when the S01 AERI was 
installed next to the C1 AERI and it stabilized on 9/30/2005, it was observed that the noise 
levels on the newly installed S01 AERI were much lower than for the C1 AERI. Therefore, the 
excessive noise of the C1 AERI is not due to the fundamental nature of the extended range 
detector but instead due to failure within the detector. 

The failure could be due to a poor D* value of too high a detector temperature. It could 
also be caused by optical alignment issues. In either case, the spectral radiance data 
have much more noise and that results in larger error bars when using the radiance data, 
especially long wave data as monitored by the LW_HBB_NEN flag.

On 9/30/2005, the S01 AERI, which is next to the C1 AERI, came on-line and is producing 
low noise data. The S01 data should be used instead of the C1 data where low noise 
requirements are needed.

On 6/26/2006, the S01 AERI went offline due to a laser failure.  The C1 AERI was moved to 
the connex where data were within reasonable limits for an extended range detector.  
Beginning 20060701, the C1 data are the preferred AERI data set at the NSA Barrow location.
