Groundwater N₂O: compilation of published observations (Table S1) and recomputation script (Data S1) for "Groundwater nitrous oxide: the IPCC emission factor is the wrong shape of parameter"

Supporting data for an Opinion submitted to Global Change Biology. Table S1 compiles 77 published records of dissolved N₂O in groundwater (31 primary, 45 secondary, 1 tertiary), with provenance for every value. Data S1 is a self-contained Python 3 script that recomputes every derived statistic in the paper from the published table entries of Weymann et al. (2008, Biogeosciences 5, 1215–1226) and Weymann et al. (2010, Biogeosciences 7, 1953–1972) and draws Figure 2. No external data are required.
