(2016). Derived annual statistics of rainfall, streamflow and acidity for the Nant Esgair Garn catchment, Llyn Brianne, Mid Wales, UK. (1982 to 2012). NERC Environmental Information Data Centre 10.5285/00185590-537e-40e4-969c-039f44b4dad9 This dataset comprises of derived annual statistics for measures of rainfall, streamflow, temperature and stream acidity (pH) for a stream, draining a small, approximately 0.6 square kilometres, upland grassland catchment. The stream, Nant Esgair Garn, drains into the Llyn Brianne reservoir, Powys, United Kingdom. The data are for a 31 year period covering 1st April 1982 to 1st April 2012. The streamflow and acidity data are derived from 15 minute resolution observations throughout the calendar year 2013 from associated stream gauging and water quality stations on the Nant Esgair Garn. The monthly rainfall measures presented, were derived from local rain gauges. The monthly temperature measures presented were derived from observations at a weather station near Talgarth, Powys. Routines within the Lancaster University Computer-Aided Program for Time-series Analysis and Identification of Noisy Systems (CAPTAIN) Toolbox for Matlab were used to develop a dynamic model of these data. These models were then used to simulate the 31-year record for which monthly statistics were derived. The statistics were derived to develop greater understanding of the controls on the long-term dynamics of aquatic biodiversity observed by other researchers in this stream. The work was part of the Diversity in Upland River Ecosystem Service Sustainability (DURESS) project, NERC grant NE/J014826/1. Members of staff from the Lancaster Environment Centre, Lancaster University installed, maintained and downloaded the stream gauging and water quality stations and also carried out statistical analysis of the data.

Data from each data logger were downloaded at regular intervals onto a laptop. Raw data were then transferred to a secure data store created for the DURESS project, hosted at Lancaster University. Records for local rain gauges were requested from the data owners. Temperature data were requested from the Met Office from observations at a weather station near Talgarth, Powys. The requested data for both rainfall and temperature were held in the DURESS secure data store. Final data were derived from these raw data using analysis in the Matlab programming environment. Values were exported in Excel spreadsheets and then into comma separated values for ingestion into the EIDC.
