JGR’s 2015 Impact Factor

Thomson-Reuters released the 2015 Impact Factors and the value for Journal of Geophysical Research is 3.3. This is a 0.1 drop from the journal’s Impact Factor of 3.4 in 2014 and 2013 . Basically within the noise of year-to-year variation, but it went down a tenth instead of up, which is disappointing.

Here’s the Thomson-Reuter’s logo, just so we have a graphic to go with this post, with a link to their page on this topic:

            The Impact Factor is calculated as the average citations in year 2015 of papers published in 2013 and 2014. Thomson-Reuters also calculates a 5-year Impact Factor and the 2015 value for JGR is 3.7, again identical to the 2013 and 2014 values to two significant digits.

Thomson-Reuters still has all sections of JGR combined in this value. So, I don’t know what it is specifically for JGR Space Physics.

In good news for the space physics community, AGU’s Space Weather Journal rose from 2.1 to 2.4 in its 2-year Impact Factor, and from 1.9 to 2.3 in its 5-year Impact Factor. Woohoo for Space Weather!

Like last year, I’ll download the Journal Citation Report, take a closer look at the numbers behind this index, and write a follow-up post.
