The data are fractional coverage of plant functional/surface types, carbon content in vegetation, carbon content in soil. The data are the result of simulations conducted in the JULES land surface model, of several complementary pathways for increasing forest coverage and forest density during the 21st century. A historical simulation covering 1880-2000 is included, followed by seven future simulations for the main simulation period of 2001-2100. This is followed by an extended run for 50 further years based on 2090s climate. Driven by Representative Concentration Pathway (RCP2.6) climatology at N96 resolution (1.25 deg latitude, 1.875 deg longitude).
