Description
This data set contains model values from 3 simulations produced with the isotope-enabled atmosphere GCM MIROC5-iso, in which tritium has been implemented. The simulations are for the period 1979-2018 and were performed with different natural tritium production rates. A complete description can be found in Cauquoin, A., Fourré, É., Landais, A., Okazaki, A., and Yoshimura, K.: Modeling natural tritium in precipitation and its dependence on decadal variations of solar activity using the atmospheric general circulation model MIROC5-iso, J. Geophys. Res. Atmos., 129, e2023JD039745, https://doi.org/10.1029/2023JD039745, 2024.
The 3 different simulations are:
- MB2009_3H_cte: with constant long-term average tritium production rate values over time from Masarik and Beer, 2009 (https://doi.org/10.1029/2008JD010557);
- CRAC_3H_cte: with constant long-term average production rate values over time from CRAC:3H model (https://doi.org/10.1029/2020JD033147);
- CRAC_3H_solar: with monthly mean tritium production rate variations from CRAC:3H model due to modulation of GCR by heliomagnetic and geomagnetic fields over time.
The model data can be downloaded as netcdf files:
