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.

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".

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.

SGP/SWATS/E20 - Incorrect Soil Moisture Data
DataStreams:sgpswatsE20.00, sgpswatsE20.b1
Description:
Due to failure of an electronic component (apparently caused by the onset of 
precipitation), the temperature rise readings from both the west and east profiles (trise_W, trise_E) 
are incorrect at all depths. This also causes the matric potential (soilwatpot_W, 
soilwatpot_E) and water content (watcont_W, watcont_E) data to be incorrect.

The dimension "depth" in the netCDF files was incorrectly reported as 8, and has been 
changed. Newer files with the correct smaller depth dimension do not have extra placeholder 
values and thus are smaller in size.
