On 1 July 2025, NIWA merged with GNS Science to become Earth Sciences New Zealand.

Atmosphere

World class research contributing to our understanding of greenhouse gases, ozone depletion, and urban air pollution.

MethaneSAT

Detecting and quantifying methane emissions by satellite. The core mission of this unique satellite is to support reductions in methane emissions around the world, primarily by reducing leaks from oil and gas production. NIWA's Dr Sara Mikaloff Fletcher is leading a science programme to develop capability to map agricultural emissions and determine the best places for the satellite to look for methane emissions around the world.
