Subject: | SGP/EBBR/E4 - Wind Direction Sensor Malfunction |
DataStreams: | sgp30ebbrE4.b1, sgp15ebbrE4.b1, sgp5ebbrE4.b1 |
Description: | During two periods recently, the wind direction sensor at E4, Plevna, KS malfunctioned. The first time period was caused by water in the connector to the sensor. The second period was apparently a result of an electronics problem in the sensor circuitry. On June 30, at 1646 GMT sensor S/N 3036 was removed and replaced with S/N 3034. On July 11, at 2003 GMT, sensor S/N 3034 was replaced with S/N 3038. The periods of time listed above are inclusive for the 30 minute data. Slightly less of the 5 and 15 minute values were affected (at the beginning or end of the periods), as is obvious from the sensor replacement times. All of the data should be considered incorrect. The affected data are: 5 minute: res_ws, wind_d, sigma_wd 15 minute: mv_wind_d 30 minute: res_ws, wind_d, sigma_wd |
