Paris, 27 June 2019: EDP Sciences is pleased to report excellent results in the 2019 Journal Citation Reports® (JCR) published by Clarivate Analytics.

Twenty-one EDP Sciences journals are tracked, over half of which show an increase in their Impact Factor with nine increasing by over 10%.

Astronomy & Astrophysics – now over 6

Astronomy & Astrophysics has earned an increased Impact Factor of 6.209 – up 11.6% from last year. Its Impact Factor has risen steadily over the past four years and the increase is a fitting achievement in its 50th anniversary year.

Since its launch in 1969, Astronomy & Astrophysics has been publishing the highest quality, pioneering, scientific research. It is now the leading original research journal in its field and has retained its rank of 10/69 in the Astronomy and Astrophysics category which has more journals in it than last year. Its special issues are particularly valued by the community and include Gaia Data Release 1 and Planck 2015 results which would have contributed to this year’s Impact Factor. (The more recent open issue Gaia Data Release 2 and Planck 2018 are also available.)

Journal of Space Weather and Space Climate – significant increase

The Journal of Space Weather and Space Climate is an international open access journal which has seen a rise in its Impact Factor to 2.821 from 2.333 last year. This represents an increase of 20.9%. Notably, it also enjoys a strong five-year Impact Factor of 3.368. (“A 5-Year Impact Factor shows the long-term citation trend for a journal.” Clarivate Analytics

The journal continues to innovate to meet the needs of its audience and recently launched the " Agora " supplement for papers on public outreach, historical accounts, commentaries, and meeting and project reports. Agora papers are reviewed by members of the Editorial Board, indexed similarly to regular JSWSC papers, and citable. The Journal of Space Weather and Space Climate has moved up in all three categories in which it is tracked and now ranks solidly at 30/86 (Meteorology and Atmospheric Sciences), 25/69 (Astronomy and Astrophysics) and 30/84 (Geochemistry and Geophysics).

Strong subject areas - Mathematics and also Materials Science, Engineering and Technology

Four journals in the mathematics portfolio are published in partnership with the Société de Mathématiques Appliquées et Industrielles (SMAI) and are considered to be high-impact journals of excellence. Three of these are included in the JCR - ESAIM: Control, Optimisation and Calculus of Variations, ESAIM: Mathematical Modelling and Numerical Analysis and ESAIM: Probability and Statistics – and all three have seen increases to their Impact Factors. In particular, ESAIM: Probability and Statistics now stands at 0.652 following a 32.3% increase from last year and ESAIM: Mathematical Modelling and Numerical Analysis ranks 39/254 in Applied Mathematics.

In the area of Materials Science, Engineering and Technology, Oil & Gas Science and Technology for Engineering makes an impressive leap of 31.8% to 1.867 and is ranked 4/19 in Petroleum Engineering. Mechanics & Industry sees a 13.4% rise to 0.747 and Metallurgical Research & Technology enjoys an increase of 11.7% to 0.641.

The Impact Factors for many other journals continue to increase or hold steady which is encouraging in a competitive climate. Notable amongst the increases is Radioprotection which has increased by 104% to 0.458. This is the largest percentage increase amongst all the EDP Sciences journals. Aquatic Living Resources also gains 64.6% to achieve an Impact Factor of 0.864 and RAIRO-Operations Research increases by 33.7% to 0.639. The European Physical Journal Applied Physics (EPJ AP) remains consistent at 0.800.

“As Managing Director of EDP Sciences, it is my pleasure to receive such good news about so many of our journals”, commented Agnès Henri. “Of course, we are mindful of an evolving landscape in which ‘impact’ can be measured in a number of ways. Impact factors are one indicator of the quality of the content we publish. Nevertheless, success in the JCR is to be congratulated as it represents the dedication and labour of our editors, reviewers and authors and the high value of our peer-review work in collaboration with our fantastic editorial boards. We continue to explore new ways of supporting the scientific community and have recently become a signatory to the DORA declaration. We hope that our efforts will be rewarded whatever measurement is applied to our broad range of publications.”

Context

This year, the JCR cover “more than 11,500 journals from over 2,550 publishers in approximately 230 disciplines from 80 countries.” ( JCR fact sheet )

According to Laurissa Gann of The University of Texas MD Anderson Cancer Center Library, during 2017, the top 5% of journals tracked by JCR had impact factors approximately equal to or greater than 6. Around two-thirds had an impact factor equal to or greater than 1. Read the post – What is considered a good impact factor?
