NIM/ECOR/M1 - Data Suspect for NW and East Wind Directions
DataStreams:nim30ecorM1.b1
Description:
Data for these wind directions must be closely evaluated to determine if it is correct or 
incorrect.  Problem will remain for the entire extend of the NIM deployment.
Measurements:nim30ecorM1.b1:
  • rotated covariance uw(cvar_rot_uw)
  • vw covariance(cvar_vw)
  • rotated covariance wc(cvar_rot_wc)
  • mean value of out of range values and spikes of t -9999 if no spikes(mean_spk_t)
  • CO2 flux(fc)
  • mean sonic temperature (t), i.e. virtual temperature(mean_t)
  • corrected sensible heat flux(h)
  • latent heat flux(lv_e)
  • rotated covariance vw(cvar_rot_vw)
  • rotated mean w(mean_rot_w)
  • mean water vapor concentration (q)(mean_q)
  • covariance wq(cvar_wq)
  • rotated covariance wt(cvar_rot_wt)
  • rotated covariance wq(cvar_rot_wq)
  • mean value of out of range values and spikes of q -9999 if no spikes(mean_spk_q)
  • momentum flux (dynamic)(k)
  • mean co2 concentration (c)(mean_c)
  • uw covariance(cvar_uw)
  • covariance wc(cvar_wc)
  • mean value of \spike\ w samples(mean_spk_w)
  • wT covariance(cvar_wt)
  • mean w (vertical) wind component(mean_w)
  • friction velocity(ustar)
  • mean value of out of range values and spikes of c -9999 if no spikes(mean_spk_c)

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)
