Subject:
SGP/EBBR/E2 - EBBR E2 Incorrect Data
DataStreams:sgp15ebbrE2.b1, sgp5ebbrE2.b1, sgp30ebbrE2.b1
Description:
During the indicated period, when either home signal is in the hundreds, all
soil heat fluxes, soil moistures, net radiation, air temperatures, bowen 
ratio, sensible heat flux, and latent heat flux are incorrect.  This 
condition usually results from an AEM circuit problem that allows the home 
signals to go high and corrupts the data.  The cause has never been 
determined.

Comments added by Marv Wesely: 
David Cook said that this is a very rare occurence; it's happened about
three times in total for all EBBRs.  The problem might be on the circuit
boards (moisture?), but that is only a guess. The problem has always
disappeared by itself after a while.
