Subject: SGP/EBBR/E13 - Reprocessed and Corrected: Incorrect data logger program
Affected Datastreams: sgp30ebbrE13.b1
Description DATA REPROCESSED and CORRECTED: The soil moisture data for the time period 20080229 - 20100304 was incorrect. It's likely that the proper procedure was not followed during a preventative maintenance visit and an older or an incorrect EF data logger program was installed, greatly reducing the soil moisture values. The data was corrected by the equation given in the DQR and was archived February 2017. Please retrieve the reprocessed data for use in your analysis. You may find these data using the ARM Discovery tool at the following link: http://www.archive.arm.gov/discovery/#v/results/s/finst::ebbr/fsite::sgp/ffac::sgp.E13 ORIGINAL DQR CATEGORY: Red( Incorrect) REPROCESSED and CORRECTED DATA ARCHIVED:2017-02 REPROCESS IDENTIFICATION NUMBER: RID 1301 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- The soil moisture data is incorrect. It's likely that the proper procedure was not followed during a preventative maintenance visit and an older or an incorrect EF data logger program was installed, greatly reducing the soil moisture values.

Subject: SGP/EBBR/E13 - Wind direction failure
Affected Datastreams: sgp5ebbrE13.b1
Description The EBBR wind direction was stuck at 135 degrees; this reading indicates a failure of the sensor electronics.
Measurements
  • wdir_vec_mean (Wind direction vector mean)
  • wspd_vec_mean (Wind speed vector mean)
  • wdir_vec_std (Wind direction vector mean standard deviation)
