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. |

Description: | A shading problem occurred with this instrument. The problem is severe enough that it is suggested to not use the direct or diffuse data during the affected period. |

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: | nsamfrsrlangleyC2.c1, nsamfrsrlangplotC2.c1, nsamfrsrC2.a0, nsamfrsrC2.b1 |
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. |

Description: | Instrument was experiencing shading problems. Because of the very low sun angles it is difficult to determine what ranges of data are OK. Mentor suggests avoiding data covered by this DQR. |
