Subject: | SGP/MFRSR/E15 - Instrument noise |
DataStreams: | sgpmfrsrE15.a0, sgpmfrsrE15.b1, sgpmfrsrlangleyE15.c1, sgpmfrsrlangplotE15.c1 |
Description: | Intermittent negative spikes in some channels and the head temp. A start date of 20050401 has been identified, but the problem may precede that date. 20050401 is the first date with obvious negative spiking. The instrument was on its way to failure, which it did just moments after this DQR ends. Interested users should examine the data closely, and remove affected points. Look for spikes in some channels, but not in others at the same time. |

Description: | This site was resurrected Feb 2008, but the first data didn't roll in until early March. Initial data showed an obvious shading problem. Site maintenance resolved the problem. Avoid data between 1500 and 2000 UTC. |

Description: | On 20090327 the shadowband stopped functioning. This was likely the result of severe weather. Maintenance on 20090407 resolved the problem just before 1800. Do not use data covered by this DQR. |

Description: | There was a feature in the data in the morning hours. Field techs reported the shadowband was aligned properly, but the sun was partially striking the diffuser over the top of the shadowband. Maintenance on 6/30 helped a lot, and 7/2 was the last day it may have still been an issue. |
