Subject:
SGP/ECOR/E10 - Incorrect CO2 fluxes
DataStreams:sgp30ecorE10.b1
Description:
The analog CO2 signal from the LI-7500 to the sonic anemometer became very noisy and 
incorrect CO2 fluxes resulted. Sonic anemometer was replaced.
Measurements:sgp30ecorE10.b1:
  • CO2 flux(fc)

Subject:
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)
