SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR 
Header

The units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in the 
EBBR 30 minute netcdf header have been incorrect from the beginning 
of processing the data into netcdf files.  The correct units are 
MJ/m^3/C.

This does not affect the data quality.

SGP/EBBR/E7 - Soil Heat Flow #5 Incorrect

After a while, the teflon slides on the AEMs warp from
heat and use.  This tends to make the AEM drag, jam, and get hung.
This happened at E7 EBBR.

SGP/EBBR/E7 - Energy Storage Incorrect, Fluxes Incorrect

The half hour after restart of the CR10 datalogger, the soil temperatures for the 
beginning of the period are missing.  Therefore the soil energy storage and surface flux values 
are also incorrect.

SGP/EBBR/E7 - Water in Net Radiometer Domes; Surface Fluxes are Incorrect

The net radiometer top dome was punctured by migrating birds.  This alone does not cause 
incorrect net radiation measurements.  However, when it subsequently rains, water collects 
in the bottom dome, causing the net radiation measurements to be too large during the 
day and too small at night.

were incorrect when this occurred.

SGP/EBBR/E7 - Pressure Sensor Data Incorrect

The E7 pressure sensor suffered
from spikes in pressure, which were related to 
increases in voltage during the day as the 
solar panels charged the battery.  These spikes
were not of a magnitude that would affect the 
30 minute surface fluxes.

Replacement of the pressure sensor solved the problem.

SGP/EBBR/E7 - Pressure Too High

When data collection resumed after a missing period, the barometer pressure
had become very high, 102 kPa, which was not correct.  This condition resulted
from an incorrect calibration being used. Sensible heat flux was overestimated 
by about 4% and latent heat flux underestimated by about 4% because of the 
high pressure readings.

SGP/EBBR/E7 - Wrong Datalogger Program

The wrong version 9 datalogger program (unit 12 instead of 13) was installed
during the period listed, causing soil heat flows to be 2 to 3 W m-2 too
high, pressure to be 0.35 kPa too high, and soil moistures to be 10% too low.

Effects on the sensible and latent heat flow are much smaller than the system error.

SGP/EBBR/E7 - Improved EBBR CR10 Program

Effective 20050322.1900, the EBBR.E7 CR10 program was revised to improve 
the quality of the primary measurements as follows:
   
1) An RMS procedure is used to determine max and min limits of acceptable
soil heat flow.  This is applied to the individual soil sets.  Measurements
outside the limits are rejected and the measurements within the limits are
used to calculate the average soil heat flow.
   
2) Max and min limits are used to determine incorrect values of net
radiation, sensible heat flux (h), latent heat flux (e), and automatic
exchange mechanism (AEM) signal.  If AEM signal is outside the limits, h 
and e are set to 999s.  If net radiation is outside the limits, h and e are 
set to 999s. If h or e are outside the limits, h and e are set to 999s.
   
Virtually no incorrect soil measurement will affect the primary 
measurements of h and e.
   
By setting h and e to 999s, it can be easily seen that the primary 
variables are incorrect; no other interpretation is possible.
   
Prior to 20050322, the improved CR10 program was NOT in effect.  DQRs have
been submitted for known instances of incorrect soil measurements which
affected the quality of the primary measurements of h and e.
   
Note: the DQR begin date is the begin date of the sgp30ebbrE7.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE7.a1).

SGP/EBBR/E7 - Average Soil Heat Flux Incorrect

A typo in the version 9 EBBR program caused average soil heat flow to be zero, resulting 
in both sensible and latent heat fluxes being approximately 20 watts per meter squared too 
large during the middle of the day.

SGP/EBBR/E7 - Net Radiation Incorrect; Sensible and Latent Heat Fluxes Incorrect

The top dome of the net radiometer was cracked; net radiation, and sensible and latent 
heat flux measurements were incorrect.

SGP/EBBR/E7 - metadata corrections

On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E7 data collected by ARM back to the installation of the 
instrument in May 1993. Please see the current metadata for correct information.  These 
changes do not affect data values or quality.	

The changes are summarized below:
1) Update of "sensor location" information
2) Addition of installation dates for the systems
3) Correction of soil moisture units (from "by volume" to "gravimetric")

SGP/EBBR/E7 - Barometric Pressure Incorrect

The pressure measurement sometimes dropped to zero during daytime because of 
unstable battery voltage.

• Barometric Pressure(atmos_pressure)

• Barometric Pressure(atmos_pressure)

SGP/EBBR/E7 - Fluxes and Gradient Measurements Incorrect

The left AEM aspirator was not working during this period, resulting in incorrect gradient 
and flux measurements.
