Subject:	SGP EBBR E9 - E9 EBBR AEM Hung, Data Incorrect
DataStreams:	sgp5ebbrE9.b1, sgp30ebbrE9.b1, sgp15ebbrE9.b1
Description:	A worn AEM belt caused the AEM to hang frequently. Gradient measurements, sensible heat flux, latent heat flux, and Bowen ratio are incorrect during the indicated periods. The AEM hung on 2/9/01 because of icing from an ice storm.
Suggestions:
