SWSC Impact factor 2013: 2.519

In 2014 Thomson-Reuters computed for the first time a two-year impact factor for SWSC, based on articles published in SWSC in the years 2011 and 2012 and cited in 2013. This 2013 impact factor is 2.519 (1.333 excluding self citations, i.e., references in SWSC articles to SWSC articles). The Immediacy Index (citations in 2013 of SWSC articles published in 2013) is 0.600. This is comparable to the relevant numbers for the AGU Space Weather journal, the only other journal known to us with prime emphasis on space weather.
