Subject: | SGP/SWATS/E1 - Reprocess: Wrong Calibration |
DataStreams: | sgpswatsE1.00, sgpswatsE1.a1, sgpswatsE1.b1 |
Description: | Two sensor connections were switched. The East 125-cm sensor was plugged into the East 85-cm sensor's connection, and vice versa. Technicians corrected the problem on 1440 GMT, 08/02/00, and returned the instrument to service 10 minutes later at 1450 GMT. As the datalogger was confusing the 2 sensors, incorrect calibrations were applied. The correct calibrations can be applied to the raw data to obtain the correct temperature rises, soil moisture, etc. However, this is a rather large amount of work to apply toward just 1 measurement profile. This has been identified as a medium priority reprocessing task. |

Subject: | SGP/SWATS/E4 - Incorrect "trise", "soilwatpot", and "watcont" |
DataStreams: | sgpswatsE4.a1, sgpswatsE4.b1 |
Description: | The "trise" values are too high, therefore the dependent "soilwatpot" and "watcont" measurements are also incorrect. For the first date range: "trise_W", "trise_E", "soilwatpot_W", "soilwatpot_E", "watcont_W", and "watcont_E" are incorrect for all 16 sensor locations (each depth on both profiles). For the second date range: "trise_W", "trise_E", "soilwatpot_W", "soilwatpot_E", "watcont_W", and "watcont_E" are incorrect for the lowest 8 sensor locations (the 60cm, 85cm, 125cm, and 175cm depths on both profiles). |

It is believed that this 2nd data record was the result of a clock adjustment and reflects a small portion of the hour integration period it represents. The 2nd record was removed from the data. The 190700 record in the data represents the ARM best estimate of data for that time. |

DataStreams: | sgpswatsE1.00, sgpswatsE1.b1 |
Description: | Between the 06GMT and 07GMT measurements on January 14th, it appears that some sort of non-atmospheric moisture source affected the 4 shallowest sensors (5-cm West & East, 15-cm West & East). No precipitation was recorded at the site, but data indicate a sharp increase in soil moisture that caused suspicious behavior that gradually lessened through January 23rd. Animal intrusion, but more probably adolescent mischief, is suspected. |

Subject: | SGP/SWATS/E5 - T_rise values too high |
DataStreams: | sgpswatsE5.b1 |
Description: | The temperature rise values (trise_W, trise_E) are too high (> 20 deg C). Water potential is calculated from a rise (and subsequent drop) in temperature in the sensor that is normally ~1-5 degrees C. When the T_rise is too high, the soil moisture data is dubious at best and unusable at worst. Due to the high T-rise (from which water potential and water content are derived), the moisture data is unusable. |
