Description

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.

 

The files are in netcdf or excel format:

- *.temp2_timmean.nc: annual mean 2m air temperature (°C)

- *.d18Op_timmean.nc: annual mean d18O of precipitation (permil)

- *.dexp_timmean.nc: annual mean d-excess of precipitation (permil)

- E6_LR_ERA5.precip_timmean.nc and E6_LR_ERA5.precip_timmean.nc: annual mean precipitation from ECHAM6-wiso T63L47 (mm/month)

- E6_LR_ERA5.d18Oqvi_timmean.nc and E6_LR_ERA5.d18Oqvi_timmean.nc: annual mean d18O of vertically integrated water vapor from ECHAM6-wiso T63L47 (permil)

- E6_LR_ERA*.qtot_*_timmean.nc: u and v components of annual mean water vapor transport from ECHAM6-wiso T63L47 (kg/m/s)

- E6_LR_ERA*_tropics_mermean.q.nc: meridional mean between 15°S and 15°N of the modeled annual mean specific humidity from ECHAM6-wiso T63L47 (kg/kg)

- E6_LR_ERA*_tropics_mermean.d18Oq.nc: meridional mean between 15°S and 15°N of the modeled annual mean d18O of water vapor from ECHAM6-wiso T63L47 (permil)

- echam_wiso_seasonal_signals_*.xlsx: modeled monthly mean variations of 2m air temperature, precipitation, d18O of precipitation and d-excess of precipitation according to the 4 simulations at Ankara, Belem, Halley Bay, Reykjavik, Valentia and Vienna for the period 1979-2018.

- echam_wiso_subdaily_signals_*.xlsx: modeled (sub-)daily variations surface specific humidity, d18O of surface water vapor and d-excess of surface water vapor according to the 4 simulations at Ankara, Mase, Niwot Ridge and Summit.
