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

• Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux)
• Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux)
• Radiation, net(net_radiation)

• net_radiation_mv

SGP/EBBR/E2 - EBBR E2 Wind Speed Iced

The anemometer was frozen stopped by freezing rain.  Indicated data was incorrect.

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

An ice storm froze the wind speed sensor to a stopped condition.

The wind speed and residual wind speed measurements are incorrect.

This sensor failure does not affect the sensible and latent heat fluxes.

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 - 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")

SGP/EBBR/E2 - Windspeed sensor failure

The windspeed sensor developed an abnormally high wind speed threshold due to worn 
bearings.

Wind speeds were often measured to be too low.  Inspect the data to identify suspect time 
periods.

SGP/EBBR/E2 - Net Radiation and Fluxes Incorrect

The net radiometer was tipped 37 degrees eastward, resulting in apparent
solar noon being 2.5 hours early.  The net radiation error results in incorrect sensible 
and latent heat fluxes.

SGP/EBBR/E2 - AEM Ventilator Dangling - Sensible and Latent Heat Fluxes Incorrect

The right AEM ventilator unit with temperature and humidity sensors inside was dangling 
from the AEM.  Therefore, the gradients of temperature and relative humidity and thus 
sensible and latent heat flux are suspect for this period.  Often, the fluxes look reasonable.

SGP/EBBR/E2 - EBBR Biannual Checks

During EBBR 3 month checks the Automatic Exchange Mechanism is disabled 
(reflected by home signals near zero) so that the two aspirator units
can be placed at the same height.  The measurements during these periods 
do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), 
or latent heat flux (e), nor do the air temperature and relative humidity 
measurements indicate correct gradients.  Checks performed before or after the 
AEM is disabled also lead to some incorrect data.  Incorrect 5, 15 minute and 
half hour data occurs for periods indicated.

SGP/EBBR/E2 - EBBR AEMs Not Exchanging (Iced Or Fuse Blown)

The EBBR AEM stopped exchanging because of icing at during this time
period.

The calculations of Bowen ratio, latent heat flux, and sensible heat
flux are incorrect for the time period indicated.  The other

SGP/EBBR/E2 - EBBR Net Radiometer Domes Pierced, Water Inside - Data Affected

The upper dome of the EBBR net radiometers was punctured.
After the puncture, water collected in the top and/or bottom dome.  The
water was removed and the dome was replaced during PM visits. 

 In some cases, the puncture and water resulted in incorrect data. 
Comparison with net radiation values from surrounding EBBR sites and the
SIRS is neccesary to determine if the EBBR net radiation data 
are correct or incorrect.

It is often difficult to tell from the data when the punctures occurred,
but they would have existed for no more than 2 weeks, since the domes
are checked during each two-weekly PM visit.

Incorrect net radiation data results in the latent heat flux and
sensible heat flux also being incorrect.

SGP/EBBR/E2 - EBBR E2 Wind Direction Sensors Frozen

Wind direction sensors were frozen stalled during this period.
Wind direction from 0630 through 1100 GMT.  Data values that 
were affected were:

 5 minute: sigma_wd, wind_d
15 minute: mv_wind_d
30 minute: sigma_wd, wind_d

• Wind direction, vector, lower, 1-min avg(wdir_vec_mean)
• wdir_vec_std

• wdir_vec_mean_mv

• wdir_vec_std
• Wind direction, vector, lower, 1-min avg(wdir_vec_mean)

SGP/EBBR/E2 - EBBR E2 Incorrect Data

During the indicated period, when either home signal is in the hundreds, all
soil heat fluxes, soil moistures, net radiation, air temperatures, bowen 
ratio, sensible heat flux, and latent heat flux are incorrect.  This 
condition usually results from an AEM circuit problem that allows the home 
signals to go high and corrupts the data.  The cause has never been 
determined.

Comments added by Marv Wesely: 
David Cook said that this is a very rare occurence; it's happened about
three times in total for all EBBRs.  The problem might be on the circuit
boards (moisture?), but that is only a guess. The problem has always
disappeared by itself after a while.

SGP/EBBR/E2 - EBBR E2 3 Month Check

During EBBR 3 month checks the Automatic Exchange Mechanism is disabled
(reflected by home signals near zero) so that the two aspirator units can be
placed at the same height.  The measurements during these periods 
do not produce correct outputs of bowen ratio (bowen), sensible heat flux
(h), or latent heat flux (e), nor do the air temperature and relative 
humidity measurements indicate correct gradients.  Checks performed before 
or after the AEM is disabled also lead to some incorrect data.  Incorrect 5,
15 minute and half hour data occurs for the period indicated.

SGP/EBBR/E2 - EBBR E2 Six Month Checks

During EBBR 6 month checks (formally called 3 month checks) the Automatic 
Exchange Mechanism is disabled (reflected by home signals near zero) so that
the two aspirator units can be placed at the same height.  The measurements
during these periods do not produce correct outputs of bowen ratio (bowen), 
sensible heat flux (h), or latent heat flux (e), nor do the air temperature
and relative humidity measurements indicate correct gradients.  Checks 
performed just before or after the AEM is disabled also lead to some 
incorrect data.  Incorrect 5, 15 minute and half hour data occurs for the

SGP/EBBR/E2 - EBBR E2 Net Radiation Incorrect - Water in Bottom Dome

Water entered the net radiometer top dome through a hole made, probably,
by migrating birds (this happens every Spring and Autumn) and accumulated
in the bottom dome.  This causes nighttime net radiations to be too large
and daytime net radiations to be too small.  The data are therefore incorrect.
