Subject: | SGP/ECOR/E14 - Fluxes and Most Measurements Incorrect |
DataStreams: | sgp30ecorE14.b1 |
Description: | The ECOR system was having major problems during this period and most measurements were incorrect most of the time. |

Subject: | SGP/ECOR/E5 - Reprocess: Time shifted -7 hours |
DataStreams: | sgp30ecorE5.b1, sgpecorE5.00 |
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. |

Subject: | SGP/ECOR/E10 - CO2 and Latent Heat Fluxes Incorrect |
DataStreams: | sgp30ecorE10.b1 |

Subject: | SGP/ECOR/E5 - Flux Measurements Incorrect |
DataStreams: | sgp30ecorE5.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. Note: Mentor reports reprocessing will not correct this problem. |

Subject: | SGP/ECOR/E24 - Half Hours of Data Missing |
DataStreams: | sgp30ecorE24.b1 |
Description: | Individual half hours of data were missing infrequently because of a UPS problem. The extent of missing data is minimal, with only a few to several half hours missing most months. Data quality of the surrounding data times was not affected. |
