Subject: | SGP/VCEIL/B1 - REPROCESS: CBH reported in feet but labeled meters |
DataStreams: | sgpvceil25kB1.a1, sgpvceil25kB1.b1 |
Description: | The cloud base heights reported in the file are in feet despite being labelled meters. Reprocessing of this data is highly recommended. The first affected file is from 2000-11-22 when the ceilometer was brought back on line following a factory repair. The last affected file is on 2001-12-13 when the new vceil_ingest version 7.2 was released which applies the proper units conversion from feet to meters. |

Subject: | SGP/VCEIL/B1 - recurrent frequent data gaps |
DataStreams: | sgpvceil25kB1.00, sgpvceil25kB1.a1, sgpvceil25kB1.b1 |
Description: | Beginning on 07/06/2003, frequent short-term data gaps began occurring. The situation continued to worsen until the PC locked up entirely on 07/14/2003. After the computer was re-booted, the data gaps stopped and have not returned. The problem appears to be restricted entirely to the computer and does not involve the ceilometer itself. Thus, there appears to be no problem with the data records that were properly collected. |

Subject: | SGP/VCEIL/B6 - contaminated window |
DataStreams: | sgpvceil25kB6.b1 |
Description: | Backscatter has consistently high amplitude because the window was dirty. The problem was corrected when the window was cleaned. |

Subject: | SGP/VCEIL/B6 - contaminated window |
DataStreams: | sgpvceil25kB6.b1 |
Description: | The window was contamined with bird droppings producing a status warning and causing the backscatter plot to have a higher than normal amplitude. The problem was corrected when the window was cleaned during regular preventative maintenance. |
