SGP/EBBR/E13 - Wind Direction Incorrect
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
Wind direction was incorrect during the period indicated due to a sensor 
electronics failure.  On 30 August 1996 site operations replaced S/N K3035
with S/N K3034.  Correct data collection resumed.

Values that are incorrect for the period are:

5 minute:   wind_d, res_ws, sigma_wd

15 minute:  mv_wind_d

30 minute:  wind_d, res_ws, sigma_wd
Measurements:sgp5ebbrE13.a0:
  • wind direction (relative to true north)(wind_d)
  • standard deviation of wind direction (sigma theta)(sigma_wd)
  • vector wind speed(res_ws)
sgp15ebbrE13.a1:
  • Wind direction (relative to true north)(mv_wind_d)

DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.a0
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 periods indicated.

SGP/EBBR/E13 - CR10 Malfunction
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
The CR10 apparently malfunctioned on 17 July 1997.  This caused a variety 
of effects, including incorrect datalogger clock times, missing data 
periods, and some corrupted data fields.  The CR10 was replaced on 
25 July 1997; all data fields are now correct.  Data users may contact
the mentor for more detailed information on data quality during this 
period.
