Subject: | SGP/EBBR/E13 - Incorrect Sensible and Latent Heat Fluxes |
DataStreams: | sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1 |
Description: | The multiplexer to which the air temperatures were connected experienced a problem, resulting in incorrect sensible and latent heat fluxes at times. |

Subject: | SGP/EBBR/E13 - Net Radiation Too Large |
DataStreams: | sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1 |
Description: | The EBBR Net Radiation (Rn) values maintained a ~200 Wm^-2 reading because of poor cable lead connections. Sensible and latent heat fluxes were therefore overestimated. Sensible (H) and latent heat (LE) fluxes can be estimated in the following way: H (new) = H/[1 + (EBBR Rn - SIRS net radiation)/SIRS net radiation] LE (new) = LE/[1 + (EBBR Rn - SIRS net radiation)/SIRS net radiation] |

Subject: | SGP/EBBR/E13 - Soil temperature #3 offscale |
DataStreams: | sgp15ebbrE13.b1, sgp30ebbrE13.b1 |
Description: | Soil Temp Sensor 3 data were missing or offscale due to a bad connection. H and LE were not normally affected, as the EBBR program "kicked" out the incorrect temperature measurements before calculating H and LE. |
