Subject: | TWP/MPL/C2 - Power Oscillation |
DataStreams: | twpmplC2.a1 |
Description: | There is an oscillation that shows up in the reflected power and the power monitor. This oscillation shows up clearly whenever there is an absence of low (< ~5 km) clouds. Cloud return signals tend to be much larger than the level of this oscillation; however, it may introduce problems for studying aerosol distributions. The end date of this DQR is artificial in that this is as far as the QC went. |

Subject: | TWP/MPL/C2 - Nauru MPL Laser Diode accidentally off |
DataStreams: | twpmplC2.a1 |
Description: | The emission from the laser diode supply was accidentally off. The Instrument Mentor, Connor Flynn, called Nauru directly and had them turn the laser emission back on. Backscatter and cloud base data during the period between 2000-11-11 00:00 GMT and 2000-11-13 22:00 GMT should be regarded as bad or incorrect while background light data and local temperature values are acceptable. |

Description: | Shortly after 00:00 GMT on 11/11/00, the MPL Energy Monitor value dropped abruptly to zero. At about 22:00 GMT on 11/13/00, the remote handset for the laser diode supply was used to turn the laser back on. |

Subject: | TWP/MPL/C2 - Reprocess: Incorrect longitude and altitude reported |
DataStreams: | twpmplC2.a1 |
Description: | The longitude of the MPL instrument is reported as -166.916. The correct longitude is +166.916. The altitude of the MPL instrument is reported as 7.2. The correct altitude is 7.1 M. These data will be reprocessed at a low priority. |
