Subject:	SGP/SIRS/E12 - Power supply problem affecting solar tracker
DataStreams:	sgpsirs20sE12.a0, sgpsirsE12.00, sgpsirsE12.b1
Description:	The tracker failed during this time period due to a failed UPS. Tracker was placed on unregulated power on 8/31/2007 to correct the problem while a new UPS was ordered.

Subject:	SGP/SIRS/E11 - Failed ventilator fans
DataStreams:	sgpsirs20sE11.a0, sgpsirsE11.b1
Description:	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.
Measurements:	sgpsirsE11.b1: Downwelling Shortwave Hemispheric Irradiance, Ventilated Pyranometer, Minima(down_short_hemisp_min) Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer, Minima(down_short_diffuse_hemisp_min) Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer(down_short_diffuse_hemisp) Downwelling Shortwave Hemispheric Irradiance, Ventilated Pyranometer, Maxima(down_short_hemisp_max) Downwelling Shortwave Hemispheric Irradiance, Pyranometer, Standard Deviation(down_short_diffuse_hemisp_std) Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer, Maxima(down_short_diffuse_hemisp_max) Down-welling unshaded pyranometer voltage(down_short_hemisp) Downwelling Shortwave Hemispheric Irradiance, Ventilated Pyranometer, Standard Deviation(down_short_hemisp_std) sgpsirs20sE11.a0: Instantaneous Downwelling Hemispheric Shortwave, Unshaded Pyranometer Thermopile Voltage(inst_global) Instantaneous Uncorrected Downwelling Shortwave Diffuse, Shaded Pyranometer Thermopile Voltage(inst_diffuse)
