Key aspects of stratospheric tracer modeling

  author={Bram Bregman and Erik Meijer},
This study describes key aspects of global chemistry-transport models and the impact on stratospheric tracer transport. We concentrate on global models that use assimilated winds from numerical weather predictions, but the results also apply to tracer transport in general circulation models. We examined grid resolution, numerical diffu-5 sion and dispersion of the winds fields, the meteorology update time intervals, update frequency, and time interpolation. For this study we applied the three… CONTINUE READING
