v1 1 deg data: BGC

The Biogeochemical Cycles simulation campaign was based on E3SM version v1.1 with two configurations representing different land soil BGC approaches. In standard configuration (“v1.1”) the Converging Trophic Cascade (CTC) biogeochemistry framework was used. The second configuration (“v1.1-ECA”) was an experimental configuration using the Equilibrium Chemical Approximation (ECA) (see “V1 Land and Energy” page for more details). For each configuration 5 experiments were performed. The first one was the pre-industrial control (“piControl”) with perpetual 1850 forcing. The remaining experiments were four “historical” runs that allows for changing forcing according to historical record and spanning 1850-2014. Those experiments are designated: BCRD, BCRD, BDRC, and BDRD. The “C” in the simulation name stands for “constant” meaning CO2 concentrations are held constant throughout the model run while “D” stands for “diagnostic” meaning CO2 concentrations follow historical trajectories between 1850 and 2014. The “B” stands for biogeochemical and refers to the CO2 concentrations seen by the land, ocean and ice models as either constant (BC) or increasing over time from 1850 to 2014 (BD). The “R” stands for radiative and refers to the CO2 concentrations seen by the atmospheric model. Hence, for example, the BDRD simulation, with CO2 concentrations following historical trajectories for the land, ocean and ice as well as the atmosphere, is a fully concentration-driven simulation showing both radiative and biogeochemical climate responses to CO2.

Data Resolution

The standard resolution configuration of E3SM v1 water cycle configuration has approximate horizontal resolution of 1 deg latitude by 1 deg longitude in atmosphere (110 km grid spacing),  with ocean and sea ice grid of 60 km in the mid-latitudes and 30 km at the equator and poles, and river transport at 55 km horizontal resolution. This model configuration is described in  “v1 1 deg CMIP” page in  Scientifically Validated Configurations.
