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.

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.

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.

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.

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.

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.

Description:
On Jan 3rd approximately 1000GMT the effects of a tropical cyclone started affecting the 
installed radiometer measurements at ARM/TWP/C3(Darwin) - both Skyrad and Gndrad.  On Jan 
4th 0740 GMT the Gndrad station was shutdown to avoid damage due to the close passing of 
this storm.  Station was restarted Jan 7th 0515GMT.
