Cover: In Brahney et al. [doi: 10.1002/2015GB005137 ], (a) Community Atmospheric Model (CAM) (v4) results of the ratio of current to preindustrial TP deposition. (b) CAM (v4) results of the current to preindustrial N:P ratios in deposition. The hemispheric difference in the mass flux changes of N versus P is clearly shown. (c) Stoichiometric representation of the relative impact of P versus N displayed as a ratio of the current to preindustrial deposition rates based on results from the CAM (v4). Values are calculated as Current/Preindustrial –1 in units of C, such that P is represented as P × 106, and N as N × 6.625. Values are shown as positive (reds) when increases in P deposition dominate, and negative (blues) when increases in N dominate. See pp. 1369–1383.
