Atmosphere and climate

Understanding how the atmosphere’s chemical and physical properties are affected by natural and anthropogenic emissions is central to humankind’s efforts to reduce air pollution and limit climate change.

NILU efforts in this area began with studies of the long-range transport of pollution in the early 1970s, and subsequently resulted in the EMEP program under the Convention on Transboundary Air Pollution (CLRTAP). Since then, the institute has held key roles as an adviser to national and international processes, based on research and publication in scientific journals.
The institute’s research includes the use of observational data and models to study emissions, dispersion, transformation and deposition on a regional and a global scale. Scientists are also examining traditional issues related to greenhouse gases and air pollution as well as the overall climate system (meteorology and how the surface characteristics affect the atmosphere), and the spread of volcanic ash and radionuclides.
