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 - 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. |
