DataStreams: | sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1 |
Description: | The net radiometer dome was broken and water entered the botom dome, causing net radiation measurements, and thus sensible and latent heat flux measurements, to be incorrect. |

Description: | On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E8 data collected by ARM back to the installation of the instrument in December 1992. 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") |
