Subject: | SGP/TWR/C1 - Intermittent data loss or corruption due to maintenance |
DataStreams: | sgp1440twr21xC1.a0, sgp30twr21xC1.a1, sgp1twr21xC1.a0 |
Description: | An aerosol instrument was mounted on the same sixty meter level carriage as the temperature/relative humidity system occupies, for the Spring IOP. As a consequence of almost daily maintenance on the aerosol instrument, the carriage was lowered to ground level on a number of occasions, resulting in no temperature and relative humidity data during those maintenance periods. Most of the values in the one minute and 30 minute data are offscale if incorrect. Daily maximums and minimums may have been affected as well. All data fields during the following time periods are considered to be incorrect: Date One Minute Thirty Minute 4/12 23:25-23:59 2330 4/13 00:00-00:10 0000, 0030 4/15 18:20-23:59 1830, 1900, 1930, 2000, 2030, 2300, 2330 4/16 23:04-23:59 0000, 2330 4/17 00:00-00:09 0000, 0030, 2300, 2330 22:59-23:59 4/18 00:00-00:13 0000, 0030, 2300, 2330 22:57-23:59 4/19 00:00-00:07 0000, 0030, 2300, 2330 22:54-23:56 4/20 22:49-23:55 0000, 2300, 2330 4/21 19:58-21:11 0000, 2000, 2030, 2100, 2130 4/22 18:44-20:18 1900, 1930, 2000, 2030 4/24 18:21-19:46 1830, 1900, 1930, 2000 4/26 17:58-18:47 1800, 1830, 1900 4/27 00:38-00:52 0100 4/28 17:49-21:32 1800, 1830, 1900, 1930, 2000, 2030, 2100, 2130, 2200 4/30 14:49-15:32 1500, 1530, 1600 5/1 15:40-16:34 1600, 1630, 1700, 2230, 2300 22:13-22:41 Possible that daily maximums and minimums of temperature, relative humidity, and vapor pressure, as well as the times of those may be impacted by offscale data. |
