abstract = "Our understanding of the Galactic magnetic field (GMF) has increased considerably in recent years, while at the same time remaining far from adequate. By way of illustration, the Jansson and Farrar (2012) (JF12) GMF model is described, emphasizing how it is constrained and which features are robust or likely to change, as modeling and constraining data improve. The most urgent requirements for the next phase of modeling are a more realistic model for the relativistic electron distribution (in order to reduce the systematic error associated with interpreting synchrotron data) and a better theoretical understanding of the origin of the large-scale coherent field (in order to develop a better phenomenological parameterization of the field). Even in its current stage of development, the JF12 model allows some important conclusions about UHECR deflections in the GMF to be formulated.",

note = "Funding Information: I am especially indebted to Ronnie Jansson for many years of stimulating and fruitful collaboration in developing our model of the GMF. I also acknowledge the contributions to this review of Azadeh Keivani, Jon Roberts and Mike Sutherland for collaboration on the deflection mapping work and for allowing me to use figures from our forthcoming paper on the topic, and David Benyamin for calculating in the model of [18] . Finally, I wish to thank them and the many other persons who have generously contributed to my understanding of the GMF, interstellar medium, Galactic cosmic rays, RM and synchrotron data, and related issues, including Markus Beck, Rainer Beck, Peter Biermann, Axel Brandenburg, Jim Cordes, Paolo Desiati, Klaus Dolag, Torsten Ensslin, Carmelo Evoli, Bryan Gaensler, Daniele Gaggero, Dario Grasso, Andrei Gruzinov, Marijke Haverkorn, Carl Heiles, Deepak Khurana, Luca Maccione, Ann Mao, Nir Shaviv, Frank Shu, Andy Strong, Tobias Winchen, and Ellen Zweibel. This research has been supported by the National Science Foundation and NASA under grants NSF-PHY-1212538 and NNX10AC96G , and two NASA High End Computing grants of time on the Pleiades supercomputing cluster to carry out the high-resolution, multi-rigidity backtracking studies.",
