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. |

DataStreams: | sgp30ecorE14.b1 |
Description: | The temp_irga was too large 05/09/07 1300 GMT - 05/10/07 2000 GMT. The temp_irga was flat lined at 49.96 C 05/10/07 2030 GMT - 05/17/07 2000 GMT. The temp_irga was missing 05/17/07 2030 GMT - 05/19/07 1700 GMT. |

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. |
