Subject: | SGP/SWATS/E24 - Sensor failure |
DataStreams: | sgpswatsE24.b1 |
Description: | The readings from the 125-cm depth on the east profile began reporting missing values for all variables (tsoil_E, trise_E, soilwatpot_E, watcont_E) after maintenance corrected soil moisture data problems on May 13, 2004 at 1900 GMT. All data from this sensor are missing from this point on. |

Subject: | SGP/SWATS/E24 - Sensor Failure |
DataStreams: | sgpswatsE24.b1 |
Description: | The soil sensor at the 125-cm depth on the West side failed and is no longer reporting correct soil moisture data (trise_W, soilwatpot_W, watcont_W). Temperature data are still good. |

Subject: | SGP/SWATS/E24 - Questionable Data due to placement of instrument |
DataStreams: | sgpswatsE24.b1 |
Description: | The Cyril EF is located on a gypsum outcropping overlooking a wheat field. When the SWATS was installed, it was placed in a "hole" in the gypsum filled with soil. The IM does not believe that this is conducive to collection of data that would be representative of local soil moisture conditions due to this arrangement. While the soil temperature and moisture data are correct for the conditions in that spot, it is very likely that the gypsum surroundings create an environment that would be unlike the surrounding area, and should be aware that the data may not be representative of actual mean local conditions. |
