Weather and climate simulations are a major application driver in high-performance computing (HPC). With the end of Dennard scaling and Moore's law, the HPC industry increasingly employs specialized computation accelerators to increase computational

International audience; This paper proposes a fault-tolerant control (FTC) approach for unknown actuatorfaults based on robust control theory. The mu-analysis is used to infer closed-loop stability againstdifferent actuator faults. Further, an adapte

A classification of the degree of riming of snow crystals is established, based on a visual rating and expressed on a scale ranging from 0 (unrimed) to 5 (graupel). For 84 individual snow crystals collected from six cases over three winters, the size

The role clouds play as processors of atmospheric aerosols and trace gases was studied along the slope of Mt. Rigi in central Switzerland. Upon cloud formation many aerosols and trace gases are efficiently scavenged by cloud drops. The cloud drops ca
