The establishment of the Nansen-Zhu International Research Center (NZC) in 2003 at the Institute of Atmospheric Physis, Chinese Academy of Sciences in Beijing has significantly contributed to climate research over almost two decades. One of the results of this China-Norwegian cooperation was the foundation of the journal Atmospheric and Oceanic Science Letters (AOSL), initiated by at the directors of IAP, Huijun Wang and Nansen Center, Ola M. Johannessen, 15 years ago. On the 15^th years anniversary of the journal the two Editors-in-Chief have published:

Commemoration of the 15th Anniversary of Atmospheric and Oceanic Science Letters

First published in late 2008 and currently in Volume 15 (2022), Atmospheric and Oceanic Science Letters (AOSL) is now 15 years old. Looking back on the journey, hardships and happiness, difficulties and hope coexist.

AOSL is an international journal for providing a rapid communication channel between academic communities concerned with the interdisciplinary research areas of atmospheric science, oceanography, and closely related sciences. This approach allows the journal to cover such critical fields as climatology, extreme events, numerical models and modeling, meso- and micro-scale meteorology, physical oceanography, atmospheric chemistry, cloud physics, atmospheric radiation and remote sensing, and so on. AOSL is co-sponsored by the Institute of Atmospheric Physics (IAP) and the Chinese Meteorological Society (CMS), was working with Taylor & Francis (2016–2020), and is now published by KeAi Communications Co. Ltd. (since 2021), which was founded by Elsevier and China Science Publishing & Media Ltd.

In the past few years, AOSL has continued to expand its scientific depth and scope, and published several high-impact special topics on COVID-19 impacts, ocean reanalysis, extreme heat, CMIP6, reactive nitrogen, greenhouse gas, climate variability and predictability, ENSO, and others. Several papers have attracted wide attention and have been highly cited, such as studies on Arctic sea ice decline intensified haze pollution, extreme heat in China, future changes in thermal comfort conditions, regional earth system modeling, future changes in precipitation extremes, and global upper ocean heat content estimation.

AOSL has also strived to adapt to the rapid developments in the all-media era. Since 2013, AOSL launched its first social media campaign and now has a presence on Twitter, Sina Weibo, WeChat, EurekAlert! and other information dissemination platforms. In 2015, AOSL started to publish articles with Chinese abstracts, and moved to Open Access mode in 2016. Since 2017, AOSL has held academic seminars and editorial board meetings every year, to expand the journal influence.

Over the past 15 years, AOSL has gradually gained affirmation and wide praise from domestic and foreign academic communities due to its distinctive characteristics and rigorous style. AOSL is now included in the Emerging Sources Citation Index (ESCI), Scopus, GEOBASE, the Directory of Open Access Journals (DOAJ), Japan Science and Technology Agence, China Bibliographic Database (JSTChi), and Chinese Science Citation Database (CSCD). From 2014 to 2021, AOSL was consecutively crowned “The Excellent International Impact Academic Journal of China”.

It is our aim and responsibility to produce a high-quality journal that publishes focused issues and becomes a recognized brand. We can take these steps because of the amazing contributions from all those involved in AOSL. Thank you!

In the future, AOSL will continue to innovate and move forwards bravely whilst never forgetting its foundations and original motivation.
