20 year datasets (1993-2012): DOIs

A series of datasets is now available, covering 20 years of continuous monitoring at ECN terrestrial sites.

Our longest running terrestrial ECN sites began operating in 1992, making 1993 the first complete year of data collection. Following the addition of the 2012 data to our database, we now have 20 years of data for these sites.

To mark this milestone, we have added 18 datasets to the CEH Environmental Information Platform, and generated a Digital Object Identifier (DOI) for each of them. These datasets contain the complete run of data available from our terrestrial sites. Data for eight of the sites span the entire 20 year period. A further four sites began operating after 1993.

Accessing ECN core data

Access ECN core data at the resolutions specified in the protocols and under the terms of the ECN data policy. Data are made available through a non-exclusive, non-transferable, royalty free licence hosted on the CEH Environmental Information Platform.  You can access these datasets via the DOI links in the table below.

Acknowledging the use of ECN data

We request that you acknowledge the use of our data sets. This helps us to gauge the extent of use of each dataset 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.
