Nonlinear Processes in Geophysics (NPG) is an international, inter-/trans-disciplinary, non-profit journal devoted to breaking the deadlocks often faced by standard approaches in Earth and space sciences. It therefore solicits disruptive and innovative concepts and methodologies, as well as original applications of these to address the ubiquitous complexity in geoscience systems, and in interacting social and biological systems. Such systems are nonlinear, with responses strongly non-proportional to perturbations, and show an associated extreme variability across scales.

All sections of NPG are more than ever eager to deal with big data and artificial intelligence with new sensing, analysis, and simulation technologies. These encompass approaches ranging from data-driven research to mathematical physics.

Notice on the current situation in Ukraine

To show our support for Ukraine, all fees for papers from authors (first or corresponding authors) affiliated to Ukrainian institutions are automatically waived, regardless if these papers are co-authored by scientists affiliated to Russian and/or Belarusian institutions. The only exception will be if the corresponding author or first contact (contractual partner of Copernicus) are from a Russian and/or Belarusian institution, in that case the APCs are not waived.

In accordance with current European restrictions, Copernicus Publications does not step into business relations with and issue APC-invoices (articles processing charges) to Russian and Belarusian institutions. The peer-review process and scientific exchange of our journals including preprint posting is not affected. However, these restrictions require that the first contact (contractual partner of Copernicus) has an affiliation and invoice address outside Russia or Belarus.
