Subject: | SGP/EBBR/E25 - Reprocess: Soil Heat Flow #5 Negative Offset |
DataStreams: | sgp30ebbrE25.a1, sgp30ebbrE25.b1 |
Description: | Soil heat flow 5 was either too large negative or negative when it should have been positive; the cause of the negative offset is unknown, but is often the result of a failed J-panel over-voltage protection device. Average soil heat flow, sensible heat flux, and latent heat flux were affected; these can be recalculated using the remaining good sets of soil sensors as follows: ave_shf = (g1 + g2 + g3 + g4)/4 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf) |

Subject: | SGP/EBBR/E25 - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR |
DataStreams: | sgp30ebbrE25.b1 |
Description: | The units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in the EBBR 30 minute netcdf header have been incorrect from the beginning of processing the data into netcdf files. The correct units are MJ/m^3/C. This does not affect the data quality. |

Subject: | SGP/EBBR/E25 - metadata errors |
DataStreams: | sgp15ebbrE25.b1, sgp30ebbrE25.b1 |
Description: | During the entire span of EBBR.E25 data, the cdf data files contained a few minor global metadata errors. These errors do not affect the data values or quality. The errors include: * incomplete sensor location information * incomplete installation date information * soil moisture documented as "by volume" should have read "gravimetric" |
