Subject: | SGP/SWATS/E4 - Incorrect soil moisture data |
DataStreams: | sgpswatsE4.b1 |
Description: | The temperature rise readings on both the east and west profiles are too high. This also causes the matric potential and water content data to be incorrect. For the first, third and fourth date ranges, measurements are incorrect for all sensor locations (each depth on both profiles). For the second date range, measurements are incorrect for the lowest 8 sensor locations (the 60cm, 85cm, 125cm, and 175cm depths on both profiles). |

Description: | The temperature rise readings from all depths on both the east and west profiles (trise_E, trise_W) are incorrect. This also causes the matric potential (soilwatpot_E, soilwatpot_W) and water content (watcont_E, watcont_W) data to be incorrect. |

Subject: | SGP/SWATS/E4 - Sensor failures, 5cm and 15cm W |
DataStreams: | sgpswatsE4.b1 |
Description: | The temperature rise readings from the 15-cm depth on the west profile were incorrect from 20040212:1500 to 20040217:0800. This also caused the matric potential and water content data for the 15-cm depth to be incorrect. The temperature rise readings from the 5-cm depth on the west profile were incorrect from 20040217:2300 to 20040218:1900. This also caused the matric potential and water content data for the 5-cm depth to be incorrect. |

Subject: | SGP/SWATS/E27 - Reprocess: Incorrect calibrations |
DataStreams: | sgpswatsE27.b1 |
Description: | The calibration coefficients for the 5-cm sensor on the East profile are incorrect. This is causing incorrect soil water content (watcont_E) to be reported. |

Subject: | SGP/SWATS/E3 - Sensor failure, 60cm E |
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/E27 - Sensor failure, 85cm W |
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. |

Subject: | SGP/SWATS/E27 - Incorrect serial numbers |
DataStreams: | sgpswatsE27.b1 |
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. |

Subject: | SGP/SWATS/E27 - Sensor failure, 125cm E |
DataStreams: | sgpswatsE27.b1 |
Description: | The 125 cm E sensor tsoil measurements were very erratic and much too high, and all trise values were reporting as slightly negative or -9999. The issue started on 06/07 and corrected itself by 20:00 GMT the same day, but the problem returned on 06/10. Connections were re-seated on 6/17 to resolve the problem. |

DataStreams: | sgpswatsE3.b1 |
Description: | The temperature rise readings from all depths on both the east and west profiles were incorrect, reading near zero. This also causes the matric potential and water content data to be incorrect. |
