The UK Environmental Change Network datasets - integrated and co-located data for long-term environmental research (1993-2015)

Long-term datasets of integrated environmental variables, co-located together, are relatively rare. The UK Environmental Change Network (ECN) was launched in 1992 and provides the UK with its only long-term integrated environmental monitoring and research network for the assessment of the causes and consequences of environmental change. Measurements, covering a wide range of physical, chemical and biological ‘driver’ and ‘response’ variables are made in close proximity at ECN sites using protocols incorporating standard quality control procedures. This paper describes the datasets (there are nineteen published ECN datasets) for these co-located measurements, containing over twenty years of data (1993-2015) collected at ECN’s terrestrial sites.
