Subject:
NIM/ECOR/M1 - CO2/H20 Fluxes Incorrect
DataStreams:nim30ecorM1.b1
Description:
The analog output of the CO2/H2O sensor was not being properly acquired by the sonic or 
the data acquisition system. 

CO2 and latent heat fluxes were therefore incorrect.  All other measurements
were correct.
Measurements:nim30ecorM1.b1:
  • CO2 flux(fc)
  • latent heat flux(lv_e)
