Single-precision arithmetic in ECHAM radiation reduces runtime and energy consumption

<p>We converted the radiation part of the atmospheric model ECHAM to a single-precision arithmetic. We analyzed different conversion strategies and finally used a step-by-step change in all modules, subroutines and functions. We found out that a small code portion still requires higher-precisi...
