SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Atmospheric Environment is the international journal for scientists in different disciplines related to atmospheric composition and its impacts. The journal publishes scientific articles with atmospheric relevance of emissions and depositions of gaseous and particulate compounds, chemical processes and physical effects in the atmosphere, as well as impacts of the changing atmospheric composition on human health, air quality, climate change, and ecosystems.
Atmospheric Environment publishes original research and review articles, special issues, supplements, and New Directions columns. The articles should be of general relevance and novelty in terms of atmospheric observations, process studies, modeling, and data analysis.
A. Key topics for stand-alone articles and special issues related to atmospheric composition (Click here for visual representation of our Scope and Key Topics)
Exchange Biosphere/Ocean/Land - Atmosphere:
• Emission and Deposition
• Anthropogenic and Natural
Field and Laboratory Studies
• Relevant Atmospheric Observations (in-situ and remote sensing)
• Process Studies in Field and Laboratory
• Chemical Transformation, Composition and Sources
• Indoor Pollution, Air Quality, Human Health, Climate Change, and Ecosystem
• Validation of Emission Reductions
• Mitigation Strategies
The scope of Atmospheric Environment has atmospheric composition and impacts as its core theme. We would like to encourage scientists to submit high quality articles of sufficient novelty, contributing to atmospheric science and its implications for the environment and policy. Three fundamental questions help the Editors in reaching a decision on whether to send a paper out for review:
- Scope - is the work directly or implicitly related to atmospheric composition?
- Novelty - does the work provide a) a general and/or broader relevance (e.g. not a pure local study), b) new results or methods, and c) does it add significantly to the knowledge of atmospheric composition and its impacts?
- Quality - does the work contain high quality a) atmospheric observations, b) process studies, c) modeling exercises or d) data analysis?
We try to be flexible with novel scientific articles on issues of atmospheric composition even, if they are not directly related to atmospheric measurements (e.g. wind tunnel studies, dynamometer studies, remote sensing retrieval, etc). However, we are still cautious of purely mathematical derivations, preliminary results or insignificant case and local studies. The authors should make sure that the articles contain substantial contributions to the science of atmospheric composition before sending them for review.
