Acknowledging the use of ECN data

We kindly request that you acknowledge the use of our data sets. This helps us to gauge the extent to which datasets are used and allows us to demonstrate the value of these data for research into environmental change.

We also request that you send us one reprint of any publication that cites the use of our data. We will endeavour to add publications that use ECN data to our publications catalogue.

ECN full datasets: links to data and related protocols

Our longest running terrestrial ECN sites began operating in 1992, making 1993 the first complete year of data collection. Currently many of these datasets are available for download up to and including 2015. Data for seven of the sites span the entire 23 year period. A further four sites began operating after 1993. Sadly, monitoring at Drayton ceased in 2014. Each dataset has a unique Digital Object Identifier (DOI) to aid referencing.

The datasets are described in a paper:

Rennie, S., Andrews, C., Atkinson, S., Beaumont, D., Benham, S., Bowmaker, V., Dick, J., Dodd, B., McKenna, C., Pallett, D., Rose, R., Schafer, S., Scott, T., Taylor, C. and Watson, H. (2020). The UK Environmental Change Network datasets – integrated and co-located data for long-term environmental research (1993–2015)Earth System Science Data12, 87-107. DOI: 10.5194/essd-12-87-2020

These full datasets are available via the UKCEH Environmental Information Platform (EIP) using the links below. Click on the name to access the dataset or on the protocol code to view the protocol. ECN full datasets at the resolutions specified in the protocols and released under the terms of the ECN data policy. Data are made available through an Open Government Licence and are hosted on the CEH Environmental Information Platform.

If you require ECN data collected after 2015, please contact us and we will try to assist wherever possible on a case by case basis.

Physical parameters
