The Girnock Burn is an intensively monitored sub-catchment of the Aberdeenshire River Dee in north-east Scotland covering an area of ca. 31km2. The Scottish Government Marine Directorate, Freshwater Fisheries Laboratory (and its predecessors) have monitored the catchment to assess the status and population dynamics of Atlantic salmon since 1966.

Girnock Burn Littlemill is a long-term river temperature monitoring site in the catchment. Analyses, of temporal trends in river temperatures and the effects of logger biases are reported in Jackson et al., (2025). The datasets provided here are bias corrected daily maximum, mean and minimum river temperature, derived from automatically logged monitoring data. Prior to 2010 the data have been corrected for generic equipment biases (but not additional biases from individual units). More recent data (post 2010) are calibrated and corrected individual instrument biases.
