Energy and radiation budgets

The global energy and radiation budget is the result of complex interactions between atmospheric dynamics and solar radiation where stratospheric processes play a key role. Their detailed investigation  with particular consideration of hydrodynamic and thermodynamic conservation laws is matter of this research topic.

Methods

Box models and integrated data from circulation models such as KMCM and ICON-IAP are used for the mass- and energy-conserving simulation of global budgets. These are compared with available data assimilations. Advanced statistical methods are used to identify small climatological changes in large seasonal variations.
