Description: | Testing of the batch of centrovision filters being used in the NIMFR EF13 instrument indicate that the first four filters leak 'out of band' light. The leakage for each filter is (1)415nm 3%, (2)500nm 1-2%, (3)615nm 1-2%, (4)673nm 3%. Acceptable leakage is less than 0.5%. This leakage causes an error in the irradiance values (too high) at these four wavelengths and the optical depths calculated using this data will be too high. |

Subject: | SGP/NIMFR/C1 - Tube heater not functioning |
DataStreams: | sgpnimfrC1.a0, sgpnimfrC1.b1 |
Description: | The tube heater is not functioning properly. On 6/27/06, site operations personnel indicated the heater plug was found to be disconnected (The heater became disconnected on 6/12/06). It was reconnected and while the head temperature returned to normal, the tube temperatures are still bad. The purpose of the tube heater is to help prevent condensation from forming on the window. The mentor has not noticed any problems with the data resulting from the tube heater malfunction. However, since the instrument is technically not fully functional, this DQR is being issued. A repair attempt was made on June 7, 2007 that resulted in the tube temperatures reaching at times into the upper 50s and sometimes even the lower 60s. The high tube temps influenced the head temperature causing it to move into the upper 40s and sometimes the lower 50s. The heater was repaired on Oct 11, 2007. Though repaired, the instrument was configured to keep the tube temp in the lower 20s (deg C). This is acceptable, though to keep with instrument specifications the setting was adjusted to keep the temps in the upper 30s (deg C). This occurred on 8 Jan, 2008. |

Description: | There were problems associated with the implementation of "cloud mode" on the upgraded CSPHOT system resulting from problems with the programming on the internal EPROM. The "cloud mode" did not work properly and other observations were also affected. For example, early morning sun and almucantar observations were missing. On 4/30/2007, the instrument was re-installed with cloud mode and was verified to be working. |

Description: | Values of direct_normal_narrowband_filter2 (500 nm) were erratic at times, likely the result of a poor connection in the signal. The erratic behavior is last seen on 20081101, before the connectors were cleaned. |

Description: | Data are suspect. There is a discrepancy between the 1640 channel and the other channels. The discrepancy is possibly related to the intermittent obstruction (a lizard) found in the collimator tube. There may also be ongoing degradation of the instrument possibly related to the lizard activity and deposits. |

Description: | The AOS data was reprocessed for the AMF, SGP and NSA sites. There was an error in the processing of the corrections for the PSAP absorption signal such that a low pass filter was implemented for the scattering data used in these corrections.The difference between the corrected and previous data is < 0.05 Mm-1 (below the instrument detection limit) and should not have a significant effect on the previous data. Data will be reprocessed at a later time when more significant changes to the data processing are implemented. |
