RD1SD-base-01_Ozone

The hindcast simulations made by the European Centre for Medium-Range Weather Forecasts (ECMWF) – Hamburg (ECHAM)/Modular Earth Submodel System (MESSy) Atmospheric Chemistry (EMAC) model are performed from 1979 to 2019 with the specific dynamics nudging by Newtonian relaxation towards ECMWF ERA-5 reanalysis meteorological data, called RD1SD-base-01 simulation. The simulations are conducted at a T42 (triangular) spectral resolution corresponding to an approximately 2.8o *2.8o quadratic Gaussian grid, 90 hybrid sigma pressure vertical levels from surface up to 0.01 hPa, and with a 720s time step length. The dataset includes the monthly mean of ozone (O3_m.nc) and the diagnostic tracer O3S (O3s_m.nc), which is used in the ACPD paper by Ma, X., Huang, J., Hegglin, M., Joeckel, P., and Zhao, T.: Causes of growing middle-upper tropospheric ozone over the Northwest Pacific region, EGUsphere [preprint], https://doi.org/10.5194/egusphere-2023-2411, 2024.
