Subject:
TWP/GNDRAD/C3 - IRT power
DataStreams:twpgndrad60sC3.b1
Description:
The IRT failed to report after a planned power outage to add lightning protection modules 
to the AC power wiring. The problem was corrected when a loose power connection to the 
logger was found, rectified, and power restored to the logger.
Measurements:twpgndrad60sC3.b1:
  • Surface Infra-Red Temperature, Standard Deviation(sfc_ir_temp_std)
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
  • Effective Surface (Skin) Temperature(sfc_ir_temp)
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)

TWP/GNDRAD/C3 - IRT failed
DataStreams:twpgndrad60sC3.b1
Description:
The IRT began to fail on 4/7/2006 and failed completely (apparently due to the internal 
power supply) on 4/27. It was replaced on 5/18.

  • Surface Infra-Red Temperature, Standard Deviation(sfc_ir_temp_std)

TWP/GNDRAD/C3 - IRT bias
DataStreams:twpgndrad60sC3.b1
Description:
The IRT reported higher surface temperatures than the PIR due to corrosion on the 
terminals of the lightning protection module and a ground wire error. The corrosion was cleaned 
and the wiring corrected.
