Subject:	TWP/GNDRAD/C3 - IRT bias
DataStreams:	twpgndrad60sC3.b1
Description:	The IRT behaved erratically, jumping frequently from reporting about 50 Wm^(-2) higher than the PIR for surface irradiance values to about 100Wm^(-2) lower than the PIR. Generally, the IRT measured lower surface temperatures than expected from the PIR.

Subject:	TWP/GNDRAD/C3 - IRT malfunction
DataStreams:	twpgndrad60sC3.b1
Description:	The internal IRT power supply failed (probably due to a lightning strike on 11/14) and was drawing excessive current on the data logger's DC system. The problem was corrected by replacing the instrument with a spare.

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.

Subject:	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.
Measurements:	twpgndrad60sC3.b1: Effective Surface (Skin) Temperature(sfc_ir_temp) Surface Infra-Red Temperature, Standard Deviation(sfc_ir_temp_std) Surface Infra-Red Temperature Maxima(sfc_ir_temp_max) Surface Infra-Red Temperature Minima(sfc_ir_temp_min)

Subject:	TWP/GNDRAD/C3 - Reprocess: Longwave Calibration error
DataStreams:	twpgndrad60sC3.b1
Description:	Modified pyrgeometer calibration procedures were implemented beginning in December 2003. These modified procedures introduced a calibration bias in the longwave data. The previous procedures were re-implemented at all sites between December 2005 and February 2006 to restore proper calibrations. The data collected while the incorrect procedures were in place are being reprocessing to remove the calibration bias. Note, this also affected standard deviation, maximum and minimum data fields.
Measurements:	twpgndrad60sC3.b1: Upwelling (10 meter) Longwave Hemispheric Irradiance, Pyrgeometer(up_long_hemisp)

Subject:	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.
