Affected Datastreams: sgp30ebbrE13.b1
Description On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E13 data collected by ARM back to the installation of the instrument in September 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 systems 3) Correction of soil type 4) Correction of soil moisture units (from "by volume" to "gravimetric")

Subject: SGP/EBBR/E13 - Radiometer dome broken
Affected Datastreams: sgp30ebbrE13.b1
Description The top net radiometer dome was broken, yielding net radiation, sensible heat flux and latent heat flux that were too low. The BEFLUX (SIRS) net radiation can be used as a replacement for the EBBR net radiation. To correct the sensible and latent heat fluxes, determine the ratio of SIRS net radiation to EBBR net radiation for each daylight half hour and multiply that ratio times H and LE to obtain approximate corrected flux values.

Subject: SGP/EBBR/E13 - Wind Speed Frozen Stopped By Ice Storm
Affected Datastreams: sgp5ebbrE13.b1
Description An ice storm froze the wind speed sensor to a stopped condition. The wind speed and residual wind speed measurements are incorrect. This sensor failure does not affect the sensible and latent heat fluxes.
Measurements
  • wspd_arith_mean (Wind speed arithmetic mean)
  • wspd_vec_mean (Wind speed vector mean)

Subject: SGP/EBBR/E13 - Left Air Temperature Incorrect - Fluxes Affected
Affected Datastreams: sgp30ebbrE13.b1
Description The left air temperature was incorrect, thus the Bowen ratio and sensible and latent heat fluxes were incorrect also.
Measurements
