SGP/SIRS/E19 - Tracker failure
DataStreams:sgpsirs20sE19.a0, sgpsirsE19.b1
Description:
On the evening of May 28th (5/29 0145) the E19 suntracker rewound past its limit switches 
breaking the downwelling diffuse instrument cable.  It did not move again until PM found 
it nonoperational and reset it on June 6th.
Measurements:sgpsirsE19.b1:
  • Shortwave Direct Normal Irradiance, Pyrgeometer, Minima(short_direct_normal_min)
  • Shortwave Direct Normal Irradiance, Pyrgeometer(short_direct_normal)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer(down_short_diffuse_hemisp)
  • Shortwave Direct Normal Irradiance, Pyrgeometer, Standard Deviation(short_direct_normal_std)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer,
    Maxima(down_short_diffuse_hemisp_max)
  • Downwelling Shortwave Hemispheric Irradiance, Pyranometer, Standard Deviation(down_short_diffuse_hemisp_std)
  • Shortwave Direct Normal Irradiance, Pyrgeometer, Maxima(short_direct_normal_max)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer,
    Minima(down_short_diffuse_hemisp_min)
sgpsirs20sE19.a0:
  • Instantaneous Uncorrected Downwelling Shortwave Diffuse, Shaded Pyranometer
    Thermopile Voltage(inst_diffuse)
  • Instantaneous Direct Normal Shortwave Irradiance, Pyheliometer Thermopile
    Voltage(inst_direct_normal)
