Subject:
SGP/SIRS/E1 - failed SIRS multiplexer
DataStreams:sgpsirs20sE1.a0, sgpsirsE1.00, sgpsirsE1.b1
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).

Subject:
SGP/SIRS/E1 - Unknown - Downwelling shaded longwave measurement incorrect
DataStreams:sgpsirs20sE1.a0, sgpsirsE1.00, sgpsirsE1.b1
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.
