Subject:
SGP/SIRS/C1 - Solar tracker failure
DataStreams:sgpsirsC1.b1, sgpsirs20sC1.a0
Description:
Solar tracker was not operating correctly during the specified time periods. Data from the 
direct normal instrument (short_direct_normal), and diffuse shaded global instrument 
(down_short_diffuse) were adversely affected.
Suggestions: 
Data are not recoverable.
Measurements:sgpsirsC1.b1:
  • Shortwave Direct Normal Irradiance, Pyrgeometer, Standard Deviation(short_direct_normal_std)
  • Shortwave Direct Normal Irradiance, Pyrheliometer, Maxima(short_direct_normal_max)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer(down_short_diffuse_hemisp)
  • Shortwave direct normal irradiance, pyrheliometer, minima(short_direct_normal_min)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Pyranometer, Standard
    Deviation(down_short_diffuse_hemisp_std)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Pyrgeometer, Minima(down_short_diffuse_hemisp_min)
  • Downwelling shortwave diffuse hemispheric irradiance, pyranometer, maxima(down_short_diffuse_hemisp_max)
  • Shortwave direct normal irradiance, pyrheliometer(short_direct_normal)

sgpsirs20sC1.a0:
  • Instantaneous uncorrected downwelling shortwave diffuse, shaded pyranometer
    thermopile voltage(inst_diffuse)
  • Instantaneous direct normal shortwave irradiance, pyrheliometer thermopile
    voltage(inst_direct_normal)
