Subject: | SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR |
DataStreams: | sgp30ebbrE12.a1, sgp30ebbrE13.a1, sgp30ebbrE15.a1, sgp30ebbrE20.a1, sgp30ebbrE22.a1, sgp30ebbrE26.a1, sgp30ebbrE4.a1, sgp30ebbrE7.a1, sgp30ebbrE8.a1, sgp30ebbrE9.a1 |
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. (NOTE: The actual begin date of some of these data streams is as early as 7/4/93. This DQR applies to all 30m EBBR data.) |

Subject: | SGP/EBBR/E7 - Soil Heat Flow #5 Incorrect |
DataStreams: | sgp15ebbrE7.a1, sgp15ebbrE7.b1, sgp30ebbrE7.a1, sgp30ebbrE7.b1 |
Description: | Soil Heat Flow Plate #5 data was intermittently incorrect at first (values too small negative), then was almost constantly so during the last half of the period. Comparison of the individual soil heat flows will quickly show the times that soil heat flow #5 was incorrect. |

Description: | After a while, the teflon slides on the AEMs warp from heat and use. This tends to make the AEM drag, jam, and get hung. This happened at E7 EBBR. Replacement of the AEM resolved the problem. |

DataStreams: | sgp30ebbrE7.a1, sgp30ebbrE7.b1 |
Description: | The half hour after restart of the CR10 datalogger, the soil temperatures for the beginning of the period are missing. Therefore the soil energy storage and surface flux values are also incorrect. |

DataStreams: | sgp15ebbrE7.a1, sgp15ebbrE7.b1, sgp30ebbrE7.a1, sgp30ebbrE7.b1, sgp5ebbrE7.a1 |
Description: | The net radiometer top dome was punctured by migrating birds. This alone does not cause incorrect net radiation measurements. However, when it subsequently rains, water collects in the bottom dome, causing the net radiation measurements to be too large during the day and too small at night. |
