UK Environmental Change Network (ECN) atmospheric nitrogen chemistry data: 1992-2019

Data represent the mass of nitrogen dioxide (NO2) collected by diffusion tubes, and corresponding estimates of atmospheric NO2 concentration, at terrestrial Environmental Change Network (ECN) sites using either the original ECN protocols or using commercially available Gradko NO2 samplers. Tubes are deployed for periods of two weeks.

This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

THIS DATASET IS BEING GENERATED AND IS EXPECTED TO BECOME AVAILABLE IN MARCH 2023.
