Processing Record for this file: (Make notes here unique for this file) Loading 1/16 - 2/1/2014 Data loaded from detarred, dezipped files from the DMF No dilution used for this period. Valid ambient data commenced on or about 14-01-26 03:54 As always, data not reported for T(blue) < 0.7 Multiple local events, probably associated with frequent on-site generator use, contaminate many stretches of this period. Consult the Operator logs for specific periods. Impactor in place. HOWEVER, signal wired backwards. The 10 and 1 in the primary data files are reversed. This has been corrected here in the Mentor QA/QC'd data files using: root:psap_out:impactor = root:inputfolder:wave11==10 ? 1 : (root:inputfolder:wave11==1 ? 10 : root:inputfolder:wave11) and the following notation put in Comment 1: Impactor polarity reversed in raw file. Corrected here. Some evidence of supermicron particles.
