SGP/SIRS/E18 - Instrument noise problem

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.
