SGP/EBBR/E7 - Pressure Sensor Data Incorrect

The E7 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.
