Here, we provide the selected fields used in our study, Quantifying Carbon Cycle Extremes and Attributing Their Causes Under Climate and Land Use & Land Cover Change from 1850 to 2300 (in review), from CESM1(BGC) fully-coupled runs from 1850 to 2300, comprising of historical (1850-2005), Representative Concentration Pathway 8.5 (2005-2100), and Extension Concentration Pathway 8.5 (2101-2300). In these simulations, land and ocean biogeochemical processes experienced the same trajectory of increasing atmospheric CO2. The ensemble member that has constant plant functional type (PFT) distribution has "pftcon" in the file name; the other simulations have dynamic LULCC forcing. Fore more information of the comparison between simulations with LULCC and without LULCC of CESM1(BGC), please see Mahowald et. al. (2017). We acknowledge and thank the Community Earth System Model (CESM) Biogeochemistry Working Group (BGCWG) for performing the CESM1(BGC) simulations.
