SGP/EBBR/E15 - 3-Month Check
DataStreams:sgp5ebbrE15.b1, sgp30ebbrE15.b1, sgp15ebbrE15.b1
Description:
During EBBR 3 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 the period above.
