SGP/SWS/C1 - Instrument offline for annual calibration
DataStreams:sgpswsC1.b1, sgpswsauxC1.b1
Description:
SWS instrument was taken offline for an annual calibration.  

Comparision of the December 19, 2007 annual calibration with the previous annual 
calibration done on November 8, 2006 shows very little change in the instrument sensitivity over 
2007.  From our analysis, there is effectively no change in the silicon spectrometer 
sensitivity from 400 to 981 nanometers.  The InGaAs spectrometer shows a slight decrease in 
sensitivity of 1 to 2% over the wavelength range of 982 to 2150 nanometers, which is within 
our expected error range.  Characterization of the change in sensitivity from 350 to 400 
nanometers over the year is a bit more difficult to determine and maybe greater than our 
expected error of 2%.  The science team at the University of Colorado is currently 
working on this problem.

Description:
There was a distinct cosine curve in the AOD data, which indicated a problem with the 
instrument, possibly due to a bad eprom in the control box.  The instrument was removed from 
service on 7/24/08 and replaced on 9/24/08.
