SGP/EBBR/E20 - Fuse Blown in AEM

When the EBBR system restarted on 15 Oct. 2003, the AEM
malfunctioned.  Surface fluxes data during this period
are incorrect.

SGP/EBBR/E20 - Reprocess: Soil Temperature Probe #1 Measurements Spiked

This affected a number of measurements that are dependent on the 
soil temperature measurements.

SGP/EBBR/E20  - Water in Net Radiometer, Surface Fluxes 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.

• vector wind speed(res_ws)
• standard deviation of wind direction (sigma theta)(sigma_wd)

SGP/EBBR/E20 - Pressure Sensor Data Incorrect

The E20 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.

not affect the primary measurements (net radiation, soil heat flow, sensible heat flux, 
latent heat flux).

SGP/EBBR/E20 - Soil Moisture #4 and Soil Temperature #4 Incorrect

#4 reported low values (steady 16%) during this time period.

The sensible and latent heat fluxes were not affected by this problem, only
soil temperature and soil moisture #4.  See soil temperatures and soil moistures from sets 
#2, #3, and #5 for correct values (note: soil temperature #1 was having problems during 
the same time).

metadata changes apply to all EBBR.E20 data collected by ARM back to the installation of the 
instrument in April 1993. Please see the current metadata for correct information.  These 
changes do not
affect data values or quality.

SGP/EBBR/E20 - Reprocess: Wind Direction 20 Degrees Low

The EBBR wind direction was found to be misaligned 20 degrees low. 

This bias should have had no effect on the res_ws or sigma_wd measurements.

• wind direction (relative to true north)(wind_d)

• Wind direction (relative to true north)(mv_wind_d)

• wind direction (relative to true north)(wind_d)

SGP/EBBR/E20 - Reprocess: Wind Direction 65 Degrees Low

The wind direction sensor reported wind directions that were 65 degrees too low because of 
a mis-alignment.

This bias should have no effect on the res_ws or sigma_wd measurements.

The wind direction data could be re-processed by adding 65 degrees.

• wind direction (relative to true north)(wind_d)

• Wind direction (relative to true north)(mv_wind_d)

• wind direction (relative to true north)(wind_d)

SGP/EBBR/E20 - Wind Direction 50 Degrees High

The wind direction was offset high about 50 degrees.

• wind direction (relative to true north)(wind_d)

• Wind direction (relative to true north)(mv_wind_d)

• wind direction (relative to true north)(wind_d)

SGP/EBBR/E20 - Wind Direction Incorrect

The wind direction differed from the co-located SMOS by 50 deg during part of the stated 
period and the electronics had failed completely resulting in a constant 135 degrees for 
the following dates and times:
08/15 0230-0430, 0830-1530 and 09/03 0200-0300, 0500 - 09/10 2230.

Sensible and latent heat fluxes were not affected by this problem.
