Trends in greenhouse gas concentrations at Baring Head, 1972–2016
New Zealand's Environment Reporting Series: The Ministry for the Environment and Statistics New Zealand
We report on GHG concentrations in ‘clean air’ measured at Baring Head, near Wellington. These measurements give us a good idea of global concentrations and help us infer long-term impacts on ocean acidity, temperature, sea level and glaciers. The trend was assessed using the Theil-Sen estimator and the Two One-Sided Test (TOST) for equivalence at the 95% confidence level. More information on this dataset and how it relates to our Environmental reporting indicators and topics can be found in the attached data quality pdf.
