SBS/GNDRAD/M1 - Upwelling longwave initial problems

The Upwelling Longwave signal was not present in the datastreams until 1746 UTC on 
9/23/2010. The signal was then very noisy and frequently above empirical limits (575 W/m^2) 
between 1700 and 2200 UTC until 2208 on 9/28/2010 when it was adjusted upward about 50 W/m^2.
