Following the release of the latest CiteScores by Scopus, we are pleased to report significant increases for a number of our journals. The highest increase of 1.7 goes to Mathematical Modelling of Natural Phenomena. Its 2021 CiteScore is 5.7 and it sits firmly in Q1 of both the Applied Mathematics and the Modeling and Simulation categories. In 2020, MMNP was the first maths journal in the world to transition to a Subscribe-to-Open (S2O) open access model.

Astronomy & Astrophysics is another title that has done particularly well and is up by 1.6. Its 2021 CiteScore is 9.9 (Q1) and we look forward to further success following its transition to S2O in 2022. Yet another S2O journal to perform well is RAIRO - Operations Research which also increased by 1.6.

Our other top performing journals are all open access, namely:

• Journal of Space Weather and Space Climate (+0.9 to 5.8)
• Parasite (+0.5 to 4.5)
• OCL - Oilseeds and fats, Crops and Lipids (+0.5 to 3.4)
• SICOT-J (+1.2 to 2.9)
• Aquatic Living Resources (+0.5 to 2.8)

We are also pleased to see that Acta Acustica and Hydroécologie Appliquée have been awarded their first CiteScores.

Scopus began providing CiteScores 11 years ago. They are now available for more than 27,000 titles in 332 disciplines. According to Scopus, “CiteScore metrics deliver greater insight into research impact and influence… researchers can use CiteScore to help determine where to publish and showcase their research as well as identify serial titles to read.”

We are delighted to see the high-quality content published by these journals continuing to make an impact in their respective communities and proud of their continued growth. We would like to thank all our Editors, reviewers and authors for their hard work which has contributed to the 2021 CiteScores.
