This dataset and associated Shiny App (https://scotland.shinyapps.io/sg-srtmn-data/) were developed to allow users to visualise quality controlled data from streams and loch outflows monitored as part of the UK Upland Waters Monitoring Network (UWMN). A range of temperature summary metrics have been generated for each of the sites, from daily maximum, mean or minimum river temperatures depending on the metrics selected. Metrics are only generated where data is available for >95% of the time period. Users should familarise themselves with the 'Metrics' and 'How to use data' pages of the associated Shiny App for details on how each of the metrics are calculated and how they should be interpreted.

The UWMN was initially established as the UK Acid Water Monitoring Network (UKAWMN) in 1988 to provide information on status and trends in the chemistry and biology of upland waters in response to atmospheric deposition of acidifying pollutants. In recent years the network was diversified and is a valuable resource for understanding the effects of multiple stressors on upland freshwater environments, including climate change. Continuous temperature monitoring was added to the network to support this broader remit and includes monitoring of river temperatures (often at loch outflows).
