Subject: | SHB/GNDRAD/C1 - Surface viewed by sensors is disturbed |
DataStreams: | shbgndrad60sC1.a1, shbgndrad60sC1.b1 |
Description: | At some point during this period, a load of snow was removed from the arms of the GNDRAD stand and deposited onto the surface directly underneath the sensors. Up to 4cm of snow had fallen just prior to this event. |

Subject: | SHB/GNDRAD/C1 - Surface viewed by sensors is occasionally shaded |
DataStreams: | shbgndrad60sC1.a1, shbgndrad60sC1.b1 |
Description: | The shadow of the Des Grosseillers and other pieces of equipment cause the area underneath the GNDRAD stand to be shaded sometimes between the hours of 10 and 21 GMT. On 05/24/98 an operator reported: "Between about 10:15 and 10:45 the shadow of the Des Groseilliers falls over the GNDRAD stand and instruments. The operator used to service the GNDRAD after servicing the SKYRAD near solar noon. However, because access to the GNDRAD is from the south, this placed his shadow beneath the instruments which was readily apparent in the data. The operator altered his schedule to service the GNDRAD either early in the morning or late at night when he would not significantly shade the sensed surface." Another operators report on 05/23/98 noted that, for the NET, during the time from 10 GMT to 21 GMT, "The shadows of the legs of the groundstand consecutively pass through the snow directly in the middle of the stand at these times. " Other example of shading can be seen on 06/14/98.A full report on shadowing would need to be derived from a variety of instrumentation under clear skies. |

DataStreams: | shbgndrad60sC1.a1, shbgndrad60sC1.b1 |
Description: | Heavy rain and fog commenced on 07/01/98 (approximately 14:00). The operator reported on 07/01 at 23:30 that the domes were covered in rain droplets. Since the exact starting time is unknown, the last confirmed time of a clean dome is logged here. Furthermore, the operator did not report a cleaning until 07/04/98 so that is used as the end time for this period of questionable data. |

DataStreams: | shbskyrad60sC1.a1, shbskyrad60sC1.b1, shbskyrad60sC1.00 |
Description: | With winds gusting in excess of 20 knots, the stand may have been shaking slightly. The snow and ice has melted away around the skirt of the ablation shield and underneath, so the Skystand is not as sturdy compared to 2 weeks ago. The NIP has a very narrow view angle and a slight tilt of the platform may cause the NIP to lose signal due to incorrect solar alignment. Since the exact amplitude of shaking is not known these data are considered suspect. |

Description: | Dot was about 3 degrees left of the white ring at 2300 Aug 19. Sunlight was intermittent, so it was not possible to recheck the dot after adjustment at 2307 Aug 19. When the solar alignment dot is outside the alignment ring the NIP will not be measuring the direct solar irradiance. |
