Subject: | SGP/SWATS/E18 - Planned data outage |
DataStreams: | sgpswatsE18.00, sgpswatsE18.a1, sgpswatsE18.b1, sgpswatspcpE18.a1 |
Description: | The data quality was known to be very poor, so the instrument was taken offline until the sensors were reinstalled. |

Subject: | SGP/SWATS/E18 - Physical changes to reinstallation |
DataStreams: | sgpswatsE18.b1 |
Description: | Due to the unique occurrence of a reinstallation of sensors at an existing SWATS facility, there are several differences between the existing sensor profiles at Morris and the rest of the SGP SWATS profiles. The two profiles are north/south of each other rather than east/west. Also, the horizontal separation of the profiles is 0.5 meters rather than 1.0. Sensors below the 60-cm depth were not reinstalled in an effort to avoid the susceptibility to lightning damage which was probably enhanced by the water table below 60 cm. The north/south alignment and 0.5-meter separation do not affect the significance of the data with regard to surface flux or hydrological modeling. Users should simply be aware that the sensors are configured slightly differently from the other SWATS facilities. |

Subject: | SGP/SWATS/E18 - Bogus data reported for 85cm, 125cm and 175cm |
DataStreams: | sgpswatsE18.b1 |
Description: | Since the instrument was restarted on June 7, 2003, there have been some erroneous values sneaking into the netCDF file for data at the 85cm, 125cm, and 175cm depths. Sensors do not exist at these depths and all associated variables should be reported as "-9999". |

Subject: | SGP/SWATS/E18 - Failed sensor at 5cm |
DataStreams: | sgpswatsE18.b1 |
Description: | The sensor at the 5-cm depth on the West profile has been reporting incorrect t-rise values since the instrument was restarted on June 7, 2003. This sensor has most likely failed. |

Subject: | SGP/SWATS/E18 - Incorrect and missing measurements |
DataStreams: | sgpswatsE18.00, sgpswatsE18.b1 |
Description: | There is an erroneous measurement at 2052Z on the 11th. All obs should be disregarded and probably should be deleted from the file. tsoil_W: From 1007Z on the 7th to 1707Z on the 9th: tsoil_W data is missing or incorrect at the 5cm depth. From 1807 on the 9th to 1807 on the 10th, tsoil_W is completely missing and/or incorrect. From 1907 on the 10th to 2007 on the 11th, correct tsoil_W data is available except for missing data at the 15cm depth. trise_W: All trise_W data is incorrect or missing from 1007Z on the 7th to 1807Z on the 10th. From 1907 on the 10th to 2007 on the 11th, trise_W data is missing at the 15cm depth. tsoil_E: From 1007 on the 7th to 1907 on the 9th, trise_E data is missing or incorrect except at the 5cm depth. From 2007 on the 9th to 1907 on the 10th, tsoil_E data is missing. trise_E: From 1007 on the 7th to 1907 on the 10th, trise_E data is missing or incorrect. |
