Subject: | SGP/SWATS/E27 - Incorrect Soil Moisture Data |
DataStreams: | sgpswatsE27.00, sgpswatsE27.b1 |
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/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/E27 - Incorrect soil temperature measurements |
DataStreams: | sgpswatsE27.b1 |
Description: | All of the tsoil measurements at this EF appear noisy and erratic at times, impacting all sensors and both profiles. |

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 - Reprocess: Miscalibration |
DataStreams: | sgpswatsE27.b1 |
Description: | The wiring at E27 from the Campbell Scientific 229-L sensors is backwards. Matric potential and water content data are incorrect due to incorrect calibrations being applied to temperature rise sensor data. |
