Description: | The resolution of TSI images were very poor and the colors were wrong. The clear sky appeared a reddish-brown during the day causing the processed image to be 100% opaque. The problem was corrected when the instrument was power cycled. |

DataStreams: | twptsiC1.00, twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
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. |

DataStreams: | twptsicldmaskC3.a1, twptsimovieC3.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, twptsicldmaskC1.a1, twptsimovieC1.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. |

Description: | During the evening of 7/8/2006, something caused several rust spots on one side of the hemispheric mirror which continued to grow in size and to be interpreted as clouds in the processed images. This problem was corrected during a site visit when the mirror was replaced. |

DataStreams: | twptsicldmaskC1.a1, twptsimovieC1.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. |

DataStreams: | twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
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. |

The data gaps are very short (less than one hour). Users could interpolate missing data or use alternative sensors such as the surface meteorological data available for the site. |
