SGP/SIRS/E1 - failed SIRS multiplexer
DataStreams:sgpsirsE1.00, sgpsirsE1.b1, sgpsirs20sE1.a0
Description:
Beginning 10/14, a failed multiplexer resulted in missing 
                  downwelling shortwave data and downwelling and upwelling 
                  longwave data which were much too low. The multiplexer 
                  handles data for the longwave instruments (UIR and DIR) 
                  case and dome temperatures as well as the downwelling shortwave 
                  hemispheric instrument (DS).

SGP/SIRS/E18 - Instrument noise problem
DataStreams:sgpsirsE18.00, sgpsirsE18.b1, sgpsirs20sE18.a0
Description:
Upwelling longwave data was somewhat noisy during this period. There
               was a direct relation to the case and dome thermistor measurements for 
               the upwelling longwave PIR (UIR). Data quality does not appear to be 
               greatly affected overall, though instantaneous values had greater 
               than usual variability. The noise disappeared on 10/19.

SGP/SIRS/E1 - Unknown - Downwelling shaded longwave measurement incorrect
DataStreams:sgpsirsE1.00, sgpsirsE1.b1, sgpsirs20sE1.a0
Description:
Downwelling longwave values were very noisy and out of range 
               due to a missing PIR case temperature measurement. Faulty 
               wiring to the case temperature thermistor on the downwelling 
               longwave IR instrument (PIR) was the likely cause of
               the problem.
               On 11/18, the E1 tracker and associated instruments (direct 
               shortwave -NIP, hemispheric shaded shortwave -8-48 and 
               hemispheric shaded longwave - problem PIR) were moved to a new 
               tracker stand.  Rewiring the instrument corrected the problem.

SGP/BRS/C1 - low downwelling shortwave readings
DataStreams:sgpbrsC1.00, sgpbrsC1.b1, sgpbrs20sC1.a0
Description:
Downwelling shortwave (DS) values frequently drop below -10 W/m^2 at night, and are 
consistently 20-40 W/m^2 less than the calculated downwelling shortwave during the day in 
clear-sky conditions. Corrective maintenance on 12/17/2004 corrected this offset.  It is not 
clear which CM action corrected the problem since the DS instrument cable was grounded to 
a new location and the DS ventilator fan was found in poor condition and was replaced.  
Either of these issues could have led to the problem observed in this instrument.

SGP/SIRS/E12 - Reprocessed: Longwave Calibration error
DataStreams:sgpsirsE12.b1
Description:
Modified pyrgeometer calibration procedures were implemented beginning in July 2003. These 
modified procedures introduced a calibration bias in the longwave data. The previous 
procedures were re-implemented at all sites between December 2005 and February 2006 to 
restore proper calibrations. 

The data collected while the incorrect procedures were in place have been reprocessed to 
remove the calibration bias.  The reprocessed 60 second averaged data are based on 3 
instantaneous 20 second data records rather than on 60 1 second instantaneous data records. 
Still, these data are considered far superior to the originally processed data. The 
reprocessed data were archived in October 2006.

SGP/RSS/C1 - Stability and nonlinearity corrections
DataStreams:sgprssC1.00, sgprssC1.b1
Description:
From the very beginning after deployment in May 2003 we observed several effects that we 
did not anticipate during the pre-deployment lab test.   They were: (1) Rapid drop in 
responsivity; (2) Responsivity having 1/lambda wavelike periodicity; (3) Appearance of 
nonlinearity within 3 months; (4) Larger than expected diurnal wavelength changes and long term 
wavelength drift. 

Right away we responded with development of correction algorithms and methods.  (1) and 
(2) are corrected to within 2-3% with biweekly lamp calibrations; (3) Nonlinearity factor 
is derived from calibration data and applied in correction; and (4) is efficiently 
corrected with Fourier correlation algorithm applied to every spectrum (once a minute).

Furthermore we perform Langley regression processing  (not a part of official data stream) 
that corrects longer term drifts in responsivity and  should correct calibration lamp 
biases.  The Vo's from Langley regressions are available via RSS  web page.

The overhaul of the instrument is planned to eliminate or at least reduce  nonlinerarity 
stability problems.  We hope that after the overhaul data processing would  be simplified 
and the frequency of calibrations would be reduced.
