Subject: | TWP/TSI/C3 - Missing data due to Mentor Activities |
DataStreams: | twptsiC3.00, twptsiskycoverC3.a1, twptsiskycoverC3.b1, twptsiskyimageC3.a1 |
Description: | Darwin TSI on-board image collection and processing had been turned off for Instrument Mentor to make fine tuning adjustments. Mentor then forgot to turn the on-board image collection and processing back on. All data for this time period is missing and unrecoverable. |

Subject: | TWP/TSI/C3 - Metadata Errors in NetCDF Header |
DataStreams: | twptsiskycoverC3.a1, twptsiskycoverC3.b1 |
Description: | The value of "sample_int" reported in the netCDF header is incorrect. The correct sampling interval is 30 seconds. The maximum values for the variable "sunny" is incorrect. It should be 1, not 100 as documented in the netCDF header. Users should disregard the "qc_sunny" flag during this period of time and apply their own qc check if desired. The minimum value for the variable "solar.altitude" is incorrect. It should be -90, not 10 as documented in the netCDF header. Users should disregard the "qc_solar.altitude" flag during this period of time and apply their own qc check if desired. |

Subject: | TWP/TSI/C3 - poor images |
DataStreams: | twptsicldmaskC3.a1, twptsiskycoverC3.b1, twptsiskyimageC3.a1 |
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. |

Subject: | TWP/TSI/C3 - camera failure |
DataStreams: | twptsiskycoverC3.b1, twptsiskyimageC3.a1 |
Description: | The TSI image was out of focus due to condensation on the camera lens and PC board that led to camera failure. The problem was corrected by replacing the camera with a spare and adjusting the shadowband. |

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. |

Subject: | TWP/TSI/C3 - mirror continously rotating |
DataStreams: | twptsicldmaskC3.a1, twptsiskycoverC3.b1 |
Description: | The mirror/shadowband was rotating continously because of a serial communication problem with the control board. The problem was corrected when the Ethernet-to-serial adaptor was replaced. |
