DataStreams:sgp15ebbrE22.b1, sgp30ebbrE22.b1, sgp5ebbrE22.b1
Description:
On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E22 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.	

The changes are summarized below:
1) Update of "sensor location" information
2) Addition of installation dates for the systems
3) Correction of soil type
4) Correction of soil moisture units (from "by volume" to "gravimetric")
