Description: | The long name attribute for the cloud effect fields incorrectly defines the cloud effect to be the difference between the clearskyfit and measured values: "Difference: ***fluxdn_clearskyfit - ***fluxdn_measured (***fcg)" ; The cloud effects are correctly calculated by subtracting the irradiance calculated in the clear sky fit from the measured irradiance. "Difference: ***fluxdn_measured - ***fluxdn_clearskyfit (***fcg)" ; NOTE: this is just a documentation error. The data are correctly calculated. |

DataStreams: | sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1 |
Description: | The windspeed sensor developed an abnormally high wind speed threshold due to worn bearings. Wind speeds were often measured to be too low. Inspect the data to identify suspect time periods. |

DataStreams: | sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1 |
Description: | The right Temperature-Humidity sensor failed. The measured temperature gradients were incorrect and thus the sensible and latent heat fluxes were incorrect for this extended period. The sensor was replaced March 6. |

DataStreams: | sgp15ebbrE22.b1, sgp30ebbrE22.b1 |
Description: | Soil Heat Flow 1 bounced around and went offscale at times, resulting in the EBBR program setting sensible and latent heat fluxes to 9999es. The problem ended during a PM visit, possibly because of routine checks and tightening of leads in terminal strips. |

DataStreams: | sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1 |
Description: | The wind direction sensor reported wind directions that were 65 degrees too low because of a mis-alignment. This bias should have no effect on the res_ws or sigma_wd measurements. The wind direction data could be re-processed by adding 65 degrees. |
