Subject: | SGP/EBBR/E18 - Soil Heat Flow #4 Offscale Low; Sensible and Latent Heat Flux Sometimes |
DataStreams: | sgp30ebbrE18.b1 |
Description: | Soil heat flow #4 was sometimes lower than the lower limit imposed in the EBBR programming; sensible and latent heat flux were therefore deemed to be suspect during those times. The cause of the low values is not clear, but the values are not reasonable for the vegetation type at EF18. |

Subject: | SGP/EBBR/E18 - SHF #4 Measurements Too Low; Sensible and Latent Heat Fluxes Suspect |
DataStreams: | sgp30ebbrE18.b1 |
Description: | Soil heat flow #4 was replaced at the beginning of this period. However, the soil heat flow measurements from that sensor were sometimes still lower than the lower limit imposed in the EBBR programming; sensible and latent heat flux were therefore deemed to be suspect during those times. The cause of the low values could not be determined, but the values are not reasonable for the vegetation type at EF18. To remedy the situation, the soil heat flow sensor calibration was changed so that the sensor provided measurements that resembled the other four soil heat flow sensor measurements. Soil heat flow measurements have been reasonable since the calibration change. |

Subject: | SGP/EBBR/E18 - Wind Speed Incorrect |
DataStreams: | sgp30ebbrE18.b1 |
Description: | The wind speed sensor was frozen stopped and thus wind speed was incorrect during this period. |
