The data below is output from the Bern3D intermediate complexity model and idealized CO2 increase-decrease simulations used in Jeltsch-Thömmes et al., Environ. Res. Lett. 15 (2020) 124026, https://doi.org/10.1088/1748-9326/abc4af The data are provided as .csv and .nc files There are different types of data 1) TIMESERIES DATA (Fig. 1 and 2) ================================= The name of the files indicates the variable: co2_ts.csv change in atm. co2 [ppm] cumulativeEmissions_ts.csv cumulative emissions [GtC] cumulativeAOflux_ts.csv cumulative atm-ocean C flux [GtC] cumulativeABflux_ts.csv cumulative atm-land C flux [GtC] sat_ts.csv change in surface air temperature [degC] ohc_ts.csv change in ocean heat content [10^24 J] amoc_ts.csv change in Atlantic meridional overturning circulation strength [Sv] seaice_ts.csv fraction of pre-industrial sea-ice area remaining [fraction of PI] The first row in the .csv files contains the header, which indicates the experiment. The naming convention is as follows: c4k#_### c4 indicates the maximum co2 as times pre-industrial (4 times) k# indicates the equilibrium climate sensitivity of the respective simulation in degrees C (k2 to k5) ### indicates the rate of CDR: 010: 0.1% yr^-1 010: 0.3% yr^-1 010: 0.5% yr^-1 010: 0.7% yr^-1 100: 1% yr^-1 200: 2% yr^-1 400: 4% yr^-1 600: 6% yr^-1 2) HYSTERESIS DATA (Fig. 3) =========================== The name of the files indicates the variables: cumulativeEmissions_sat.csv cumulative emissions and change in surface air temperature [degC] cumulativeEmissions_OHCsurf.csv cumulative emissions and change in upper ocean heat content (0-700 m) [10^24 J] cumulativeEmissions_o2thermo.csv cumulative emissions and change in thermocline (200-600 m) o2 [mmol m^-3] cumulativeEmissions_OM_arag.csv cumulative emissions and fraction of water in the uppermost 175 m with omegar_aragonite saturation state >3 [fraction] each file contains the time (simulation year) as well as cumulative emissions (cumuEmis) and the respective variable (same naming as in ...
