An additional reprocessing had to be performed after two errors were detected: 1: Wetproce.exe discards the two first packets of AC9 data, but the SuperModaps gives the start time associated with the very first packet. Therefore the AC9 data lag is actually 3.2 seconds lower than the lag computed from the flow rate. 2: The total backscattering coefficient was incorrectly computed for both Hydroscatt and Ecovsf.
