Description: | On 20100128 or early on 20100129 snow or ice caused the band to slip on the motor shaft. This resulted in the band not shading at all. A site visit on 2/17 appeared to resolve the problem, but the box was left open and water damaged the system. On 2/24 the logger was replaced and the shadowband aligned. Data are fine after 1900 UTC. |

DataStreams: | twpmfrsraod1michC2.c1 |
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. |

Subject: | TWP/AOD/C3 - Reprocess: airmass field is incorrectly set to -1 when failing QC. |
DataStreams: | twpmfrsraod1michC3.c1 |
Description: | The qc_airmass field indicates that values in the airmass field are set to -9999, the missing_value, when qc_airmass = 1 (QC bit 1 has tripped). In reality, the values are set to -1 and will not be filtered out by programs that automatically remove missing values. This will be fixed in a future reprocessing task. |
