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.

Subject:	SGP/ECOR/E10 - Reprocess: Wind Direction Incorrect
DataStreams:	sgp30ecorE10.b1
Description:	It was discovered that the E10 ECOR boom is aligned 17 degrees to the west of true north. Therefore, all wind direction data for the stated period is 17 degrees too high. Subtract 17 degrees from the wind direction to give the correct direction. The E10 configuration file was modified to correct this problem.

Subject:	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.
Measurements:	sgp30ecorE10.b1: average atmospheric pressure (IGRA internal sensor)(atm_pres) average temperature (IGRA internal sensor)(temp_irga)

Subject:	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.
