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

NIWA’s work includes research and consultancy on the physical and chemical processes affecting the atmosphere and climate, including global effects, stratospheric research, air quality and interactions with the surface and oceans.

Dr Katja Riedel and Dr Hinrich Schaefer discuss how NIWA's ice coring work on Taylor Glacier in Antarctica is allowing us to find out about the Earth's atmosphere in the distant past.

By analysing air trapped in ancient ice we can see how wetlands and permafrosts responded to warming periods in the past, and help predict what will happen in the future.
