High-frequency precipitation and stream water quality time series from Plynlimon, Wales: an openly accessible data resource spanning the periodic table

摘要

This scientific briefing announces the availability of a new multi-element highfrequencynwater quality data set that is openly accessible to the research community.nThe data set comprises up to 2 years of 7-hourly water quality data for two streamsnand one rainfall site in the Upper Severn catchment at Plynlimon in Mid-Wales. Thenmeasurements cover 50 analytes ranging from H+ to U and spanning six orders ofnmagnitude in concentration, including major, minor and trace elements as well asnnutrients, and they complement decades of weekly measurements of the samenanalytes at the Upper Severn. Together, the weekly and 7-hourly time series providena unique data set for studying both long-term trends and short-term dynamics. Thendata show complex behaviour over a wide range of timescales, challenging ournunderstanding of catchment processes and informing future modelling efforts.nCopyright © 2013 John Wiley & Sons, Ltd.
