Subject: | SGP/SWATS/E18 - Incorrect depth dimension |
DataStreams: | sgpswatsE18.b1
|
Description: | No sensors are installed at the 85cm, 125cm, and 175cm depths. All associated variables
should be reported as "-9999". Ignore spurious measurements. |
Measurements: | sgpswatsE18.b1: - Volumetric Water Content, West Profile(watcont_W)
- Soil Temperature, West Profile(tsoil_W)
- Sensor Temperature Rise, West Profile(trise_W)
- Soil Water Potential, East Profile(soilwatpot_E)
- Volumetric Water Content, East Profile(watcont_E)
- Sensor Temperature Rise, East Profile(trise_E)
- Soil Water Potential, West Profile(soilwatpot_W)
- Soil Temperature, East Profile(tsoil_E)

Subject: | SGP/SWATS/E18 - Intermittent data |
DataStreams: | 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. |

Subject: | SGP/SWATS/E12 - Time drift |
DataStreams: | sgpswatsE12.b1, sgpswatspcpE12.b1
|
Description: | The time synchronization server stopped working on Feb. 19th at 22:12:16 GMT. The clock
was corrected by -5600.177269 seconds on March 10th at 22:47 GMT. The recorded times for
observations are off by amounts ranging from 0 seconds on Feb. 19th to 5600 seconds on
March 10th. |
Measurements: | sgpswatspcpE12.b1: - Hourly precipitation(precip)
- time(time)
- base time(base_time)
- Time offset of tweaks from base_time(time_offset)

- Soil Temperature, West Profile(tsoil_W)
- Soil Water Potential, East Profile(soilwatpot_E)
- Sensor Temperature Rise, West Profile(trise_W)
- Volumetric Water Content, West Profile(watcont_W)
- Sensor Temperature Rise, East Profile(trise_E)
- Time offset of tweaks from base_time(time_offset)

Subject: | SGP/SWATS/E12 - Incorrect soil moisture |
DataStreams: | sgpswatsE12.b1
|
Description: | Temperature rise values were way to high (~40 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 temperature rise is too high, the soil moisture data is dubious at best and
unusable at worst. Since this "out-of-bounds" t_rise is so high, the soil moisture data
are practically unusable.
Soil temperature measurements were not affected. |
