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.

Astroparticle Physics publishes experimental and theoretical research papers in the interacting fields of Cosmic Ray Physics, Astronomy and Astrophysics, Cosmology and Particle Physics focusing on new developments in the following areas:
• High-energy cosmic-ray physics and astrophysics;
• Particle cosmology;
• Particle astrophysics;
• Related astrophysics: supernova, AGN, cosmic abundances, dark matter etc.;
• High-energy, VHE and UHE gamma-ray astronomy;
• High- and low-energy neutrino astronomy;
• Instrumentation and detector developments related to the above-mentioned fields.
Novelty and relevance Astroparticle Physics aims to only publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, or that are out of scope, such as concentrated mostly on very theoretical developments with few direct immediate observational consequences, or lacking a direct connection to either astro- or particle physics.
Astroparticle Physics may consider the publication of scientific mission proposal papers. The Editors will jointly decide on the suitability of such papers for the journal, authors are advised to contact one of the Editors directly to discuss proposals. http://www.journals.elsevier.com/astroparticle-physics/editorial-board/
