SGP/EBBR/E25 - metadata errors

During the entire span of EBBR.E25 data, the cdf data files contained a few minor global 
metadata errors. These errors do not affect the data values or quality.

The errors include:
* incomplete sensor location information
* incomplete installation date information
* soil moisture documented as "by volume" should have read "gravimetric"

• base time(base_time)
