Subject: | SGP/ECOR/E14 - CO2/H2O Incorrect |
DataStreams: | sgp30ecorE14.b1 |
Description: | The LI-7500 CO2/H2O sensor stopped working after a rainstorm. CO2 and H2O data are incorrect during the stated period. |

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/E14 - Sensor failure |
DataStreams: | sgp30ecorE14.b1 |
Description: | The water vapor output of the LI-7500 was too low, indicating that water vapor leaked into the sensor and that the chemicals are spent or there was an electronic failure. Latent heat flux was not normally affected by this problem. |

Subject: | SGP/SEBS/E14 - Instrument logger problem |
DataStreams: | sgp30ecorE14.b1 |
Description: | SEBS soil moisture measurements had been recorded as minimum soil moisture since the start of the SEBS installation at E14. Soil heat capacity calculations were also incorrect as a result of the problem. Instrument was mis-identified as ECOR in the DQPR. Since the SEBS datastream was not available to list, I have had to select an ECOR datastream just to be able to submit this DQR. Please add the SEBS to my listing of instrument systems for the purpose of submitting DQRs. |

Subject: | SGP/ECOR/E14 - Instrument logger problem |
DataStreams: | sgpecorE14.00, sgp30ecorE14.b1 |
Description: | Soil moisture measurements have been recorded as minimum soil moisture since the start of the SEBS installation at E14. Please check the wiring of the soil moisture sensors to the multiplexer as follows: 1) Check that the yellow/green leads run from MUX 2, Common, Even, H/L to CR1000 4H/Gr. 2) Check that the 50K resistor is connected between CR1000 4H and excitation VX3. Please report the results of these checks here. Thanks. |
