PluvioReader: A software for digitizing weekly siphoning-type pluviograph strip charts

Long, continuously-gaged precipitation records are needed for characterizing extreme rainfall events over sub-daily durations, as well as detecting potential historical effects of climate change. However, most such records predating the 1980s are in the form of paper strip charts (pluviograms), from which it is notoriously difficult to extract extreme precipitation depths for short durations (from a few minutes to a few hours). We propose a...
