Subject:
TWP/QCRAD/C2 - Instrument grounding problem
DataStreams:twpqcrad1longC2.c1, twpqcrad1longC2.s1
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.
Measurements:twpqcrad1longC2.c1:
  • Irradiance, longwave, downwelling, hemispheric(down_long_hemisp)
  • Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)
  • Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp)
  • LWdnTd
  • LWdnTc
  • LWupTd
  • Radiation, shortwave, downwelling total hemispheric irradiance, 1-min avg(down_short_hemisp)
  • Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal)
  • Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp)
  • Radiation, shortwave, downwelling diffuse hemispheric irradiance, 1-min avg(down_short_diffuse_hemisp)
  • LWupTc
