SGP/ECOR/E14 - Flux Measurements Incorrect
DataStreams:sgp30ecorE14.b1
Description:
The ECOR datastream was corrupted; this happens when the ECOR program produces a 
datastream of the wrong length (i.e., leaves one or more measurements out).

Fluxes and some other measurements are incorrect.

Reprocessing will not correct this problem; the raw data are corrupted.
Measurements:sgp30ecorE14.b1:
  • Water vapor density (q)(mean_q)
  • h(h)
  • average atmospheric pressure (IGRA internal sensor)(atm_pres)
  • mean co2 concentration (c)(mean_c)
  • average temperature (IGRA internal sensor)(temp_irga)
  • CO2 flux(fc)
  • latent heat flux(lv_e)

SGP/ECOR/E10 - LI-7500 Pressure and Temperature missing
DataStreams:sgp30ecorE10.b1
Description:
The LI-7500 pressure and temperature were not recorded;
the serial datastream was not being captured by the ECOR.

  • average temperature (IGRA internal sensor)(temp_irga)

SGP/ECOR/E16 - LI-7500 Pressure and Temperature missing
DataStreams:sgp30ecorE16.b1
Description:
The pressure and temperature measurements were not recorded; the LI-7500 serial datastream 
was not being captured by the ECOR system because of a serial port failure.

Some degradation of the latent and sensible heat fluxes may have occurred during high 
summer temperatures.  The error in the fluxes would be no more than 5 to 10% of the 
measurement, still well within the measurement error of the system.
Measurements:sgp30ecorE16.b1:
  • latent heat flux(lv_e)
  • h(h)
  • condensation pressure(cp)
  • average temperature (IGRA internal sensor)(temp_irga)
  • Retrieved water vapor density profile(rho)
  • average atmospheric pressure (IGRA internal sensor)(atm_pres)
  • latent heat of vaporization(lv)
