Subject: | SGP/SWATS/E10 - Sensor failure, 15cm E |
DataStreams: | sgpswatsE10.b1 |
Description: | The 15cm E sensor failed at 7:00 GMT on 06/02/2002. Values of temperature rise from this sensor often do not fail automated QC tests, but inspection of the time series reveals that the values are incorrect. Since 2002, this sensor has alternated between providing temperature rise values near 0 C, equal to -9999, or other obviously incorrect values. Soil temperature data are not affected. |

Subject: | SGP/SWATS/E1 - Sensor failure, 85cm E |
DataStreams: | sgpswatsE1.b1 |
Description: | Both trise and tsoil for the 85cm E sensor dropped out reporting values of -9999 starting on 08/24/2005. Interestingly, both this sensor and the one at 85 cm W (D040730.1) began to report data again June-August 2006. Both sensors have reported values of -9999 after this brief period through the current date. This problem impacts tsoil_E, trise_E, soilwatpot_E, and watcont_E. Instrument was removed from service 20091014. |
