SGP/EBBR - EBBR E2 Net Radiation Incorrect

The net radiometer top dome was broken and water had entered.  Net 
radiation values are therefore incorrect during the period.

The affected data are:

5 minute:  q
15 minute: mv_q
30 minute: q, h, e

The AEM kept stopping in one of three positions, none of which allow
sensible heat flux, latent heat flux, or Bown ratio to be calculated
correctly.  These and the gradient measurements are incorrect for the
period indicated.

the home 30 position (home signal about 23), or inbetween these two
(home signal 1 to 2).

SGP/EEBR/E2 - Soil Temperature #2 Incorrect

Soil temperature #2 was intermittently incorrect.
The cause is not yet known.  The indicated other measurements
were also incorrect because soil temperature #2 was used in the
calculations of the quantities.

Soil moisture (30 minute only) was affected because version 6
of the EBBR datalogger program used a multiplication of
soil temperature and soil moisture as part of the adjustment
of soil moisture for soil temperature.  This was discovered
to be a poor technique soon after it was implemented, but E2
will continue to use version 6 until a replacement EBBR unit
is available.

Changeout dates of the EBBR units can be found on the EBBR
Instrument web page.

technique soon after it was implemented, but E2 will
continue to use version 6 until a replacement EBBR

remaining good sets of soil sensors as follows:

SGP/EBBR/E2 - Net Radiometer Iced Over During Storm

The net radiometer was covered with ice from a storm.  Net radiation values are incorrect, 
and are sometimes even negative during the daytime.  Sensible and latent heat fluxes are 
therefore incorrect.

SGP/EBBR/E2  - Wind Speed Frozen Stopped By Ice

SGP/EBBR/E2 - Net Radiometer Dome Broken, Reducing Net Radiation Measurement, Fluxes 
Incorrect

The upper dome of the net radiometer was broken.  Normally this alone does
not affect the net radiation measurement.  However, in this case the 
breakage must have been more than just a bird claw hole or a crack,
resulting in obstruction of the top sensing surface of the net radiometer
and greatly reduced net radiation measurements.

Sensible and latent heat fluxes were reduced as a result.

SGP/EBBR/E2 - Improved EBBR CR10 Program

Effective 20050324.1700, the EBBR.E2 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 20050324, 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 sgp30ebbrE2.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE2.a1).

SGP/EBBR/E2 - Net Radiation Incorrect; Latent and Sensible Heat Fluxes Incorrect

The top dome of the net radiometer was broken and water entered, causing incorrect net 
radiation measurements.  This resulted in incorrect sensible and latent heat fluxes.

SGP/EBBR/E2 - 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/E2 - metadata corrections

On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E2 data collected by ARM back to the installation of the 
instrument in May 1997. 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")
