New JGR Impact Factor

The Journal Citation Reports for 2013 have been released by Thomson-Reuters, which means the new Impact Factors are out. As I have posted before, this index is a commonly-used indicator of journal quality. It’s not the only one and perhaps not even the best for JGR, but it is arguably the best known and most widely quoted. For 2012, the Impact Factor of JGR was 3.17. Note that this index does not separate the various sections of JGR but rather calculates a single value for all of the sections combined. Remember that this is calculated by taking the citations in year x to papers published in years x-1 and x-2 and dividing by the number of papers in those two years. Four numbers…that’s it.

The new JGR Impact Factor for 2013 is 3.44, an 8% increase! Fantastic! The Five-year Impact Factor also rose by a similar amount to 3.71.

By the way, with the switch to Wiley, the separate sections of JGR were given distinct ISSN numbers. This means that in a couple of years, each section of JGR will have its own Impact Factor. It will be interesting to see what this reveals. Until then, however, JGR-Space Physics is lumped in with all other sections of JGR in these and most other metrics.

  1. I have heard so many times the argument that the IF is an overestimation of the true value of JGR-Space, because it is calculated over all the section and, allegedly, the other sections would have a much higher IF if they were considered separately.
    Is it true?

    • Good question: The short answer is, I don’t know. We were told at our recent editorial board meeting that AGU will task a staff member to calculate IFs for each section of JGR, sometime in the coming months. Also, with the switch to Wiley, each section of JGR now has its own ISSN, which means that in another year or two, we will have separate IF numbers for each section. Finally, from Bob Lysak, former editor of JGR-Space, apparently AGU did this separation calculation a few years back, and JGR-Space was right in the middle…4th of the 7 sections, and close to the JGR-wide average. But really, I have no idea for 2013.

  2. Hello! Do you know if they make any plugins to protect against hackers?
    I’m kinda paranoid about losing everything I’ve worked hard on. Any
