Immersion freezing by natural dust based on a soccer ball model with the Community Atmospheric Model version 5: climate effects
We introduce a simplified version of the soccer ball model (SBM) developed by Niedermeier et al (2014 Geophys. Res. Lett. http://dx.doi.org/10.1002/2013GL058684 41 http://dx.doi.org/10.1002/2013GL058684 ) into the Community Atmospheric Model version 5 (CAM5). It is the first time that SBM is used in...
