Subject:
TWP/QCRAD/C2 - Instrument grounding problem
DataStreams:twpqcrad1longC2.s1, twpqcrad1longC2.c1
Description:
A grounding problem with the skyrad data logger (discussed in DQR D090605.2) created 
intermittent anomalous voltages and incorrect data. Days listed in this DQR are periods where 
bad data could be clearly identified; data from other days in this date range should be 
treated with caution.
Suggestions: 
null
Measurements:twpqcrad1longC2.c1:
  • Shortwave direct normal irradiance, pyrheliometer(short_direct_normal)
  • Downwelling LW Dome Temperature(LWdnTd)
  • Downwelling LW Case Temperature(LWdnTc)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer(down_short_diffuse_hemisp)
  • Upwelling LW Case Temperature(LWupTc)
  • Upwelling LW Dome Temperature(LWupTd)
  • Down-welling unshaded pyranometer voltage(down_short_hemisp)
