Subject: | SGP/EBBR/E39 - Barometric Pressure Incorrect |
DataStreams: | sgp30ebbrE39.b1 |
Description: | The barometric pressure did not trend well with the MET system barometric pressure. However, the sensible and latent heat fluxes were not deleteriously affected by the small differences of the EBBR barometric pressure from the MET barometric pressure. |

Subject: | SGP/EBBR/E39 - EBBR Flux Measurements Sometimes Incorrect for Southerly Winds |
DataStreams: | sgp30ebbrE39.b1 |
Description: | When the wheat was at it's peak and for southerly winds, the EBBR flux measurements reflected combined fluxes from both the grass between the EBBR and the wheat and the wheat itself. The EBBR AEM height was not high enough to capture fluxes from just the wheat for southerly wind directions. EBBR fluxes for northerly directions (from grass) were consistent with the ECOR measured fluxes. The EBBR AEM was raised on 2 Aug 2016 and fluxes from southerly directions have been similar to those from the ECOR since then. |

Subject: | SGP/EBBR/E9 - Some Measurements Incorrect |
DataStreams: | sgp30ebbrE9.b1 |
Description: | The wrong data logger program (for unit 6) was loaded into the E9 EBBR, instead of the correct program (for unit 15). This happened for two periods: 11/19/2015 1730 - 12/28/2015 0600 and 06/01/2016 1830 - 12/14/2016 1630. This affects a number of measurements, but the effect on the primary variables sensible and latent heat fluxes was within the measurement uncertainty. Reprocessing of the measurements would be very complicated, as we would have to back out through polynomials, etc. Since the effect on the sensible and latent heat fluxes is within the measurement uncertainty, the effort required for re-processing doesn't justify the time and expense of doing it. |
