Subject: | ENA/CCN/C1 - Problem with time fields |
DataStreams: | enaaosccn100C1.a1 |
Description: | During the ENA deployment the CCN instrument clock was not synched with a time server until 12/2/2014. Starting at about 11/03/2013 the CCN was 60 seconds slow. From that time until the time was manually corrected on 10/07/2014 at 16:00:00 the CCN time gradually got faster relative to the CPC until it was approximately 10 minutes fast. On 12/2/2014 at 20:28:30 the CCN was configured to automatically correct its time from the Unit 1 CPU. Since that time the CCN has been within 2 seconds of the time server except at startup. More recently the setting was changed to keep the CCN within about .6 sec. Generally the time is being corrected by time client about once every 3 days. There have been 2 startups since the time synching was configured. At these times the time was off by more, but was immediately corrected. On 12/30/2014 at 19:28:01 the time was fast 66.235 sec. at startup. On 01/16/2015 the time was fast 38.512 sec. at startup. The Document shows the times of the peaks used to approximate the error in the time. The time was checked about once a week and its assumed that the time drifted gradually between the times in the file. |

No data should be used for this period as ambient samples. Note: Two datastream are missing. The CAPS Extinction Monitor and the Greenhouse gas instrument. |

While the problem was being rectified, there was a period where the CPC was sampling from the instrument cabin and not from the ambient. Therefore data during this time is not representative of the ambient concentration of aerosol in the atmosphere and should not be used as such. |
