SGP/ECOR/E14 - Sensor failure
DataStreams:sgp30ecorE14.b1
Description:
The water vapor output of the LI-7500 was too low, indicating that water vapor leaked into 
the sensor and that the chemicals are spent or there was an electronic failure.

Latent heat flux was not normally affected by this problem.
Measurements:sgp30ecorE14.b1:
  • Mean H2O density(mean_q)

SGP/SEBS/E14 - Instrument logger problem
DataStreams:sgp30ecorE14.b1
Description:
SEBS soil moisture measurements had been recorded as minimum soil moisture since the start 
of the SEBS installation at E14.  Soil heat capacity calculations were also incorrect as 
a result of the problem.

Instrument was mis-identified as ECOR in the DQPR.

Since the SEBS datastream was not available to list, I have had to select an ECOR 
datastream just to be able to submit this DQR.

Please add the SEBS to my listing of instrument systems for the purpose of submitting 
DQRs.
