SGP/SIRS/E11 - Failed ventilator fans

Ventilator fans for both the downwelling shortwave hemispheric and downwelling diffuse 
hemispheric instruments failed during this time period.  The thermal effects of daytime 
heating will skew the radiometric measurements of these thermopile instruments.

No known correction can be applied.  Disregard this data or use with caution.
