SGP/EBBR/E13 - Sensible and Latent Heat Fluxes Incorrect (AEM failure)

The AEM was stuck in the home 30 position most of this period.

Therefore, the sensible and latent heat fluxes are incorrect during most of this period.

SGP/EBBR/E13 - Loose connections

The tair_bot spiked around midday, as if it is temperature related, and may have indicated 
a loose connection.

The sensible and latyent heat fluxes and Bowen ratio were incorrect when this condition 
occurred.

SGP/EBBR/E13 - metadata corrections

On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E13 data collected by ARM back to the installation of the 
instrument in September 1992.  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 systems
3) Correction of soil type
4) Correction of soil moisture units (from "by volume" to "gravimetric")
