SGP/EBBR/E7 - Data Missing

Data was missing because of a communication problem.  However, previously
missing data from 10/07-18 was recovered from the EBRR storage module and ingested, 
thereby reducing the data lost period significantly.

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.

• net_radiation

• net_radiation_mv

• latent_heat_flux
• sensible_heat_flux
• net_radiation

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")

• base time(base_time)

• base time(base_time)

• base time(base_time)

SGP/EBBR/E7 - Barometric Pressure Incorrect

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

• atmos_pressure_mv

• 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.

SGP/EBBR/E9 - Net Radiation Incorrect

There was water in the net radiometer.  

The net radiation data was incorrect.
