最近Thomson公布了各個期刊最新的影響因子，當然是根據2018年的數據計算的。每年這個時候各種關於Impact Factor不能代表期刊影響力的討論就甚囂塵上，當然今年也不例外。這裡小編整理了本公眾號最常引用的29個大氣科學領域的期刊：
整體來說，影響因子還是有一定代表性的，畢竟自己的論文被別人引用是科研人員的榮耀，證明研究是有意義的。當然也有很多人質疑期刊自引率之類的。總的來說，期刊IF都是在上升的，因為文章數量跟文章總量都在增加。

Web of Science Group highlights the key developments for 2019 as:
The journals selected for inclusion: The database is maintained and updated to reflect the ceaseless progression of research and scholarship, allowing researchers to explore new fields and see what earlier research influences and impacts evolving fields. This year 283 journals have been added, 108 of which are fully open access. The JCR report reflects cover-to-cover indexing of 2.3 million articles, reviews and other source items. The 11,877 journals hail from 81 countries across five continents;
New categories added: Careful management of the subject categories by which the journals are organised is essential to maintaining a logical content relationship within the category and to ensure that the categories are relevant to researchers and can accommodate new research areas. The report covers 236 disciplines, including the introduction of three new ones: Quantum Science & Technology (SCIE), Development Studies (SSCI) and Regional & Urban Planning (SSCI); and
Cleansing of the list: Seventeen journals have been suppressed from the JCR this year to ensure the integrity of the reports, representing 0.14% of the journals listed. The JCR is the only citation index which monitors and excludes journals that demonstrate anomalous citation behaviour including where there is evidence of excessive journal self-citation and citation stacking.
