Data for publication "Statistical characteristics of extreme daily precipitation during 1501 BCE - 1849 CE in the Community Earth System Model".

Here, the data used in Kim, W. M., Blender, R., Sigl, M., Messmer, M., & Raible, C. C. (2021). "Statistical characteristics of extreme daily precipitation during 1501 BCE–1849 CE in the Community Earth System Model" in Climate of the Past (https://doi.org/10.5194/cp-2021-6) are provided.

Two simulations covering the period 1501 BCE - 2008 CE are performed with CESM 1.2.2: the orbital-only and the full-forcing simulations. The full-forcing transient simulation includes the new long record of volcanic eruptions (https://doi.org/10.1594/PANGAEA.928646) that covers the last 3500 years. The output from the simulations is used to examine the long-term variability and characteristics of daily extreme precipitation during 1501BCE-1849 CE.

The following files are provided:

 CESM122.transient.PRECT.anom.above99th.1501BCE-1849CE_I and II: Daily precipitation anomalies above the 99th percentiles relative to 1501BCE-1849CE from the full forcing simulation. The file is split into two parts, with the first file containing the first 50% of extremes (I) and the second file containing the rest 50% (II).

CESM122.orbital.PRECT.anom.above99th.1501BCE-1849CE I and II: Daily precipitation anomalies above the 99th percentiles relative to 1501BCE-1849CE from the orbital-only simulation.

 CESM122.transient.variables.mon.1979-2008CE: monthly precipitation, temperature, and geopotential height at 500 hPa for 1979-2008CE from the full-forcing simulation.

CESM122.trans.variable_names.years: Monthly variables from the full-forcing simulation. The simulation starts from the model year 1, which corresponds to the actual year 1501BCE. The variables are solar insolation (SOLIN), clear-sky net surface shortwave radiation (FSNSC), geopotential height at 500hPa (Z500), and surface temperature (TS).

CESM122.orbital.variable_names.years: Monthly variables from the orbital-only simulation. The simulation starts from the model year 1, which corresponds to the actual year 1501BCE.

CESM122.*.log-likelihood-GPDmodel-ExtForcing: Negative log-likelihood for the stationary and non-stationary Generalized Pareto Distribution models for external forcings.

 CESM122.*.log-likelihood-GPDmodel-ModesVar: Negative log-likelihood for the stationary and non-stationary Generalized Pareto Distribution models for modes of variability.

Evolk_EVA_distribution_1501BCE-2015CE: Distribution of volcanic aerosol for CAM5, produced based on Kim et al. (2021).
