Subject: | SGP/ECOR/E10 - Sensor failure |
DataStreams: | sgp30ecorE10.b1, sgpecorE10.00 |
Description: | Due to LI-7500 (H2O/CO2 infrared gas analyzer) sensor failure all humidity and CO2 data are incorrect for the period of Jul. 14, 2004 01:00 to Aug. 13, 2004 18:00. |

Subject: | SGP/ECOR/E10 - Sensor failure |
DataStreams: | sgp30ecorE10.b1, sgpecorE10.00 |
Description: | Due to sensor failure all the parameters measured by the Infrared Gas Analyzer (water vapor density, CO2 concentration, fluxes of latent heat and CO2, etc.) are incorrect for the period of 18:30 Oct. 22, 2004 to 22:00 Dec. 14, 2004. The data is irrevocably lost. |

Subject: | SGP/ECOR/E10 - Reprocess: Incorrect H2O, CO2 |
DataStreams: | sgp30ecorE10.b1, sgpecorE10.00 |
Description: | Due to failure of analog output circuitry in the Infrared Gas Analyzer (IRGA), CO2 and water vapor parameters measured by the IRGA (water vapor density, CO2 concentration, fluxes of latent heat and CO2) were incorrectly recorded in sonic raw data files for the period of 22:30 Dec. 14, 2004 to 22:00 Jan. 11, 2005. The data could be recovered from IRGA raw serial files (00 level). |

Subject: | SGP/ECOR/E10 - Reprocess: Incorrectly flagged (marked as "bad") H2O/CO2 data |
DataStreams: | sgp30ecorE10.b1 |
Description: | Due to system clock instability on ECOR computers their system time is adjusted approximately once per hour; sometimes this adjustment leads to backward time jumps over midnight, into the previous day. In this case all the data based on CO2/H2O measurements might be erroneously marked as bad. |

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. |

DataStreams: | sgp30ecorE10.b1 |
Description: | The LI-7500 pressure and temperature were not recorded; the serial datastream was not being captured by the ECOR. |
