NPG cover
Executive editors: Ana M. Mancho, Daniel Schertzer, Olivier Talagrand & Stéphane Vannitsem

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.

01 Oct 2021 First insights from new EGU author survey

In April 2021 the EGU Publications Committee launched the first author survey to routinely ask authors about their publishing experience in EGU journals, in order to learn more about how EGU and Copernicus can serve the scientific community with their publications. Over the last 6 months, 160 contact authors answered the survey representing about 10% of the papers published during this time. We are delighted about the positive feedback and thank all authors. Please read the full report.
