Description: | The TSI at Manus has been able to remain dry and produces an image but the percentage of cloud cover is determined to be 100% even on cloud free days. Moisture in the camera lens and neutral density filter was corrupting the sky images. The lens and filter were cleaned, the moisure seals checked, the camera housing sealed, and desiccant added to both the camera housing and main electronics enclosure. On 3/23/2006, the lens was replaced and the sky images were significantly improved. |

Subject: | SGP/TSI/C1 - Birds obstructing view |
DataStreams: | sgptsimovieC1.a1, sgptsicldmaskC1.a1, sgptsiskyimageC1.a1 |
Description: | Birds were frequently in the the field-of-view and soiling the mirror, affecting the visible sky image and resulting processed cloud fraction image. Bird deterant spikes were installed on top of the camera housing and arm on 5/16 which prevented their perching on the camera so that the impact on the sky image was reduced. But birds were still present around the edges of the mirror until additional spikes were installed on top of the four corners of the enclosure on 6/14. |

DataStreams: | twptsimovieC3.a1, twptsicldmaskC3.a1, twptsiskycoverC3.b1, twptsiskyimageC3.a1 |
Description: | The mirror control board failed and was replaced with a spare. Several images were collected in the iterim that should be ignored. These images include periods when the sun was not masked by the shadowband, the camera lens was covered by red tape to protect the CCD from direct exposure to the sun and, the instrument was inside the shop for repair and testing. |

DataStreams: | twptsiC1.00, twptsimovieC1.a1, twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
Description: | The mirror was continuously spinning during different periods of the day, usually in the afternoon, causing the shadowband to not properly block the sun. This problem was corrected by removing the real-time-clock integrated circuit DSI306, or EEPROM U10, from the control board and reloading the position and time parameters. |

DataStreams: | twptsimovieC1.a1, twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
Description: | The mirror/shadowband was not turning and there was no communication with the control board. The shadowband was stuck in the position of 0 degrees from 8/29 to 9/20/2006. On 10/12/2006, the mirror was replaced, the real-time clock chip was removed and heat sinks were added to the control board, and the Ethernet hub and serial adaptor were replaced. On 1/8/2007, the slip clutch assembly, timing pulley, and timing belt were replaced (which were damaged when the mirror was replaced). These actions did not correct the problem. The instrument was swapped with the unit from Darwin so that the control board could be repaired and tested in Darwin. Several images were collected in the iterim that should be ignored. These images include periods when the sun was not masked by the shadowband or the camera lens was covered by tape to protect the CCD from direct exposure to the sun. There are also extended periods of missing data when the instrument was shutdown, waiting for parts. |

Subject: | NIM/TSI/M1 - Shadowband Misalignment |
DataStreams: | nimtsimovieM1.a1, nimtsicldmaskM1.a1, nimtsiskyimageM1.a1 |
Description: | From installation, the shadowband was positioned south at solar noon until the vernal equinox when it began to migrate counter-clockwise until reaching east 37 days later on 4/26 (about 9 days before mid-spring). The shadowband at solar noon continued to migrate until reaching its most northerly position (~15 deg) on the summer solstice (if everything was perfectly aligned, it probably would have been pointed north on this day). It then began to migrate clockwise and reached east again 56 days later on 8/16 (about 14 days after mid-summer). As expected, the shadowband reached its most southerly position on the autumnal equinox but was about 10 deg off of being due south. With the apparent alignment problem, I don't understand why the shadowband was mostly blocking the sun. When I started noticing this offset in May, I chose to leave it alone because I felt that adjusting the shadowband to where I thought it should be would cause it to not block the sun at either sunrise or sunset. The alignment was corrected on 9/29 (6 days after the day of the autumnal equinox). |

Description: | When the TSI from Darwin was installed (so the instrument from Manus could be returned to Darwin for repair) moisture in the camera lens and filter caused the sky image to be very "hazy". The U10 chip was removed from the control board, desiccant was installed inside the enclosure, additional small desiccant bags were installed inside the camera housing, the camera housing was sealed with silicon to prevent moisture ingress, and the camera lens filter was cleaned and the focus adjusted. |
