SGP/ECOR/E14 - Flux Measurements Incorrect

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.

• latent heat flux(lv_e)

SGP/ECOR/E5 - CO2 and Water Vapor Fluxes and Means Incorrect

The LI-7500 at E5 ECOR did not putting out data during this period.

Therefore, CO2 and H2O fluxes and means were incorrect during the period.

SGP/ECOR/E10 - LI-7500 Pressure and Temperature missing

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)
• average atmospheric pressure (IGRA internal sensor)(atm_pres)

SGP/ECOR/E16 - LI-7500 Pressure and Temperature missing

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.
