DataStreams: | sgpswatsE3.b1 |
Description: | The temperature rise readings from the 60-cm depth on the east profile (trise_E) were incorrect. This problem also causes the matric potential (soilwatpot_E) and water content (watcont_E) data for the 60-cm depth to be incorrect. The sensor began to behave erratically at 7:00 GMT on 07/10/2008 before an apparent failure at 10:00 GMT on 08/07/2008. Maintenance on 10/29 corrected the problem. Values of tsoil_E at the 60 cm depth are not impacted by this problem. |

Subject: | SGP/SWATS/E8 - Sensor failure, 35cm W |
DataStreams: | sgpswatsE8.b1 |
Description: | The sensor installed at 35 cm at the west profile has produced questionable data ince it was installed back in 1996. Once the sensor began to stabilize at 17:00 GMT on 07/20/99, it has produced questionable or incorrect values of temperature rise. From 07/20/99 to the present date, 35cm W temperature rise values have stayed within a range of approximately 0.8-2.0 C, while the sensor from the 35cm E profile has produced an approximate range of 1.5-4.0 C. In addition, the calibration for this sensor is so bad it is not possible to correct it using field data. The range of temperature rise values produced by this sensor is too limited to reliably re-calibrate the instrument. Under the old ARM calibration for SWATS, the calibrated reference temperature change should fall within a range of 1.45-4.00 C (the new range is 1.38-3.96 C). For this sensor, the reference temperature change has fallen within an approximate range of 0.2-1.7 C and the calibration is actually adjusting the trise measurements in the wrong direction. Therefore, all temperature rise, matric potential and water content data are all highly suspect from the 35cm W sensor. The soil temperature data appear to be OK. Instrument removed from service 20091110. |

DataStreams: | sgpswatsE27.b1 |
Description: | The 85 cm West sensor (based on location in the multiplexer) at this facility appears to have failed. After initially demonstrating problems in mid-2006, all variables from this sensor began to report as -9999 on and after 7:00 GMT on 08/04/06. Note, although this sensor is listed as 85 cm W in the data files due to its location in the multiplexer, it is actually the 85 cm E sensor in the ground. Instrument removed from service 20091204. |

Description: | The wiring at E27 from the Campbell Scientific 229-L sensors is backwards. This issue impacts the following variables but does not impact data quality: serial_numbers_W, serial_numbers_E. All serial numbers stored in the serial_numbers_W variable apply to data stored in the trise_E and tsoil_E variables, and vice versa. Thus, the user should be aware that the trise_W, trise_E, tsoil_W, and tsoil_E variables actually contain data from the opposite profile. |
