Short summary

A new methodology is presented to estimate regional-scale surface fluxes of ²²²Rn. ²²²Rn is an increasingly important trace gas which is used to calculate regional-scale greenhouse gas emissions and to validate atmospheric transport models. We tested our method at two atmospheric research stations in the Netherlands and compared our results with measurements from accumulation chambers and two recently published ²²²Rn soil flux maps for Europe.
