SGP/SIRS/E18 - Noise in upwelling longwave data

After restart due to ice storm the upwelling longwave case and dome thermistors 
experienced intermittent noise. Last seen 7/24/2007, the noise is intermittent and can last several 
days.  When noise is not apparent, upwelling longwave measurements appear normal.

Only using upwelling longwave data that has been processed with ARMs qcrad VAP during this 
time period.  Or, disregard upwelling longwave data during this time.
