DataStreams: | sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1 |
Description: | The upper dome of the net radiometer was broken. Normally this alone does not affect the net radiation measurement. However, in this case the breakage must have been more than just a bird claw hole or a crack, resulting in obstruction of the top sensing surface of the net radiometer and greatly reduced net radiation measurements. Sensible and latent heat fluxes were reduced as a result. |

These metadata changes apply to all EBBR.E2 data collected by ARM back to the installation of the instrument in May 1997. 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") |
