Description: | The logger was replaced while troubleshooting a prior issue. The replacement logger reports erratic voltages. On 20100122 the instrument stopped functioning, so the problem was likely related to a failing logger. Nonetheless, the irradiance data appear to be OK, so this DQR is being labeled as yellow/suspect. |

Description: | A refurbished system with a new logger was installed on 20100114. This was our first install in the southern hemisphere. We had an unknown software bug, and initially the instrument was set up 180 deg off in an effort to get it to shade properly. This didn't work, and I suspect is related to the weird neg dir normal values that started this DQPR. A software fix was made, and the instrument was set up correctly on March 11. From that point forward, data look OK. |

Description: | The heater was suffering from intermittent, short duration, drop outs. In July the issue became more pronounced and on July 26 it stopped functioning altogether. It began operating again on Aug 9, but was still suffering from occasional glitches. System was scheduled for replacement. Replacement system installed on 20100219. |

Description: | The linear heater board failed. It took a bit longer than usual to repair this instrument. We suspect the heater boards fail due to excessive heat, so we wanted to put a cooling solution in place at the time of the heater board replacement. This was accomplished on 20100827 @ 0300 UTC. Avoid using data covered by this DQR. |
