SGP/EBBR/E9 - EBBR Biannual Checks
DataStreams:sgp5ebbrE9.b1, sgp30ebbrE9.b1, sgp15ebbrE9.b1
Description:
During EBBR 6 month checks the Automatic Exchange Mechanism is disabled 
(reflected by home signals near zero) so that the two aspirator units
can be placed at the same height.  The measurements during these periods 
do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), 
or latent heat flux (e), nor do the air temperature and relative humidity 
measurements indicate correct gradients.  Checks performed before or after the 
AEM is disabled also lead to some incorrect data.  Incorrect 5, 15 minute and 
half hour data occurs for periods indicated.
