The Journal Citation Reports has released the impact factors for 2009.
The impact factor, one of the measures available to rank journals, is the frequency with which the "average article" in a journal has been cited in the previous two years. It is calculated dividing the number of citations to papers published in the previous two years by the total number of items published during the same period. In order and for fire related journals, these are:
- Progress in Energy and Combustion Science 12.440
- Journal of Hazardous Materials 4.144
- Proceedings of the Combustion Institute 3.510
- Combustion and Flame 2.923
- International Journal of Wildland Fire 1.901
- Building and Environment 1.797
- Fire Safety Journal 1.259
- Engineering Structures 1.256
- Experimental Thermal and Fluid Science 1.234
- Fire and Materials 1.196
- Combustion Science and Technology 1.142
- Journal of Structural Engineering 0.928
- Journal of Fire Science 0.860
- Fire Technology 0.366
- Journal of Fire Protection Engineering 0.296
Clarification (derived from the wikipedia):
The 2009 impact factor of a given journal is equal to A/B. Where A is the number of times articles published in 2007 and 2008 were cited during 2009, and B is the total number of papers published by that journal in 2007 and 2008.
