Subject: AWR/MPL/M1 - Reprocess: Ingest now includes afterpulse
Affected Datastreams: awrmplpolfsM1.b1
Description Afterpulse calibration procedures are being performed every quarter starting September 2016. Ingest has been modified to include afterpulse corrections in netcdf data files. Data needs to be re-processed starting 09/01/2016 to reflect these changes.

Subject: AWR/MPL/MPLCMASK/M1 -
Affected Datastreams: awrmplpolfsM1.b1
Description Values for the linear depolarization ratio (LDR) have been identified as too high. An error in the LDR indicates one or both of the backscatter cross or backscatter copol signals are not correct. Backscatter and LDR data should be treated qualitatively unless a correction is applied.
Measurements
  • signal_return_cross_pol (Attenuated backscatter, cross pol)
  • signal_return_co_pol (Attenuated backscatter, copol)
