Subject:
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)
