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/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. |

Subject: | SGP/ECOR/E5 - Reprocess: Time shifted -7 hours |
DataStreams: | sgpecorE5.00, sgp30ecorE5.b1 |
Description: | An inadvertant power outage caused the ECOR program to shut down abnormally. When power was restored, the timestamps on the ECOR files were 7 hours behind the correct time and the site ID was not accessed from the ECOR configuration file resulting in site ID (05) being replaced with "AN". These conditions caused the ECOR files to be unrecognizable and therefore are presently missing in the Archive. Correction of the timestamp and ID in the files should allow them to be processed and added to the Archive. |

Subject: | SGP/ECOR/E21 - Intermittent incorrect flux measurements |
DataStreams: | sgp30ecorE21.b1 |
Description: | At various times during the period, the LI-7500 CO2/H2O serial and analog signals from the LI-7500 were missing, but usually not at the same time. When the CO2/H2O serial datastream was missing, the Pressure and Temperature were missing; this did not, in itself, result in incorrect fluxes, as default values for pressure and temperature are automatically used. Fluxes were incorrect when the CO2/H2O analog datastream was missing; these times are identified by the qc checks. |
