Subject: | NSA/MFRSR/C2 - No data collected during winter |
DataStreams: | nsamfrsrC2.a0, nsamfrsrC2.b1 |
Description: | The sun does not rise above the horizon at the NSA sites between November and January each year. During this time period, the MFR instruments are removed and returned to PNNL for maintenance and calibration. The instruments are generally re-installed in March. |

DataStreams: | nsamfrsrC2.00, nsamfrsrC2.a0, nsamfrsrC2.b1, nsamfrsrlangleyC2.c1, nsamfrsrlangplotC2.c1 |
Description: | The instrument had a slight shading problem, particularly evident in the 415nm channel. The sun elevation is low which translate to high cosine correction resulting in significant noise. Data at this time of year should always be used with caution. The instrument is scheduled to be removed as soon as weather allows. |

DataStreams: | nsamfrsrC2.a0, nsamfrsrC2.b1, nsamfrsrlangleyC2.c1, nsamfrsrlangplotC2.c1 |
Description: | There is a slight shading issue occurring between 1230 UTC and 1730 UTC. It is first noticed around 6/1/2007 and is very slight. It is last noticed on 8/10/2007. This DQR runs through 8/31/2007 since the rest of the month is cloudy and it is hard to determine when the shading issue stopped. |

DataStreams: | nsamplpolC1.b1, nsamplpolavgC1.c1, nsamplpolavgC1.s1 |
Description: | The polarizer box was not recycled when the system was rebooted; thus only circularly polarized light was being emitted. Ignore all cross polarized data. |

DataStreams: | nsamplpolC1.b1, nsamplpolavgC1.c1, nsamplpolavgC1.s1 |
Description: | Even though the polarization voltage was reported as switching between circular and cross polarization states, there was no cross polarization taking place because the polarization box had not been recycled following a system reboot. You will not be able to create depolarization values. However all other processes, such as cloud base determination should be ok. |

Description: | There is a minor shading issue at high zenith angles (0530 - 1630 UTC). Due to extremely persistent cloudy conditions, maintenance was not attempted until 20090811. Cloudy conditions persisted, and it was never clear from the data if the instrument was shading properly at high zenith angles. Therefore, the DQR end date is listed as the time maintenance was performed. |
