Subject: | TWP/VCEIL/C3 - low receiver sensitivity |
DataStreams: | twpvceil25kC3.b1 |
Description: | The ceilometer reported frequent receiver alarms. There are periods when the receiver sensitivity dropped to about 50%. The problem was corrected by replacing the instrument with a spare. |

Subject: | TWP/MPL/C3 - Temporary laser failure |
DataStreams: | twpmplC3.00, twpmplC3.a1 |
Description: | No backscatter information is in the data. The backscatter data in the files during this time is solar background information only. The laser turned it's self off, reason: unknown. A power cycle of the entire system corrected the problem. |

Subject: | TWP/MPL/C3 - Backscatter profiles are inaccurate due to computer HD corruption. |
DataStreams: | twpmplC3.00, twpmplC3.a1 |
Description: | The data shows a consistent cloud deck at 7.5km with what appears to be a duplication of the data from ground zero. The temperature and energy monitor values are also affected. The computer was found with multiple corruption problems. These corruptions may have cause the ghost data at 7.5km. A chkdsk was performed which appears to have corrected the problem. |

Subject: | TWP/SMET/C3 - Reprocess: Barometric Data Changed from hPa to kPa |
DataStreams: | twpsmet60sC3.b1 |
Description: | Barometric pressure data was converted from hPa to kPa in order to standardize the measurement units among ARM sites and to conform to accepted standard units determined by the scientific community. |
