Subject: MAO/WACR/M1 - Reprocessed and Corrected: Incorrect polarization status
Affected Datastreams: maowacrM1.a1
Description DATA REPROCESSED and CORRECTED: During this period, raw data was incorrectly identifying polarization status for hour-long periods, intermittently. So some hour-long periods were correct, and some hour-long periods had polarization status swapped. The ingest was modified to identify the good and bad hourly periods from reflectivity and linear depolarization ratio images. A new ingest software was released and the WACR data were reprocessed. The data were Archived in July 2016. 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::wacr/fsite::mao/ffac::mao.M1 ORIGINAL DQR CATEGORY: Red( Incorrect) REPROCESSED and CORRECTED DATA ARCHIVED:2016-07 REPROCESS IDENTIFICATION NUMBER: RID 1249 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- During this period, raw data was incorrectly identifying polarization status for hour-long periods, intermittently. So some hour-long periods are correct, and some hour-long periods have polarization status swapped.
