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. |

DataStreams: | sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.a1 |
Description: | The E7 pressure sensor suffered from spikes in pressure, which were related to increases in voltage during the day as the solar panels charged the battery. These spikes were not of a magnitude that would affect the 30 minute surface fluxes. Replacement of the pressure sensor solved the problem. |

Subject: | SGP/EBBR/E7 - Pressure Too High |
DataStreams: | sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1 |
Description: | When data collection resumed after a missing period, the barometer pressure had become very high, 102 kPa, which was not correct. This condition resulted from an incorrect calibration being used. Sensible heat flux was overestimated by about 4% and latent heat flux underestimated by about 4% because of the high pressure readings. |

These metadata changes apply to all EBBR.E7 data collected by ARM back to the installation of the instrument in May 1993. Please see the current metadata for correct information. These changes do not affect data values or quality. The changes are summarized below: 1) Update of "sensor location" information 2) Addition of installation dates for the systems 3) Correction of soil moisture units (from "by volume" to "gravimetric") |
