ECHAM6-wiso and ECHAM5-wiso nudged simulation data for the period 1979-2018

This data set contains model values from 4 simulations produced with the isotope-enabled atmosphere GCMs ECHAM5-wiso and ECHAM6-wiso for the period 1979-2018. These simulations been performed at different spatial resolutions (T63 and T127) or with different reanalyses for the nudging (ERA5 and ERA-Interim). A complete description can be found in Cauquoin, A. and Werner, M. (2021). High-resolution nudged isotope modeling with ECHAM6-wiso: Impacts of updated model physics and ERA5 reanalysis data. J. Adv. Model. Earth Syst., 13, e2021MS002532, https://doi.org/10.1029/2021MS002532.

The 4 performed simulations, described in Cauquoin and Werner (JAMES, 2021), are: 

- E6_LR_ERA5: ECHAM6-wiso at T63L47 spatial resolution, nudged to ERA5.

- E6_LR_ERAI: ECHAM6-wiso at T63L47 spatial resolution, nudged to ERA-Interim.

- E5_LR_ERA5 : ECHAM5-wiso at T63L47 spatial resolution, nudged to ERA5.

- E6_HR_ERA5: ECHAM6-wiso at T127L95 spatial resolution, nudged to ERA5.
