has provided a new impetus to efforts to better model how space weather events can increase the density of the upper atmosphere and thus the drag satellites in low orbits can experience.

The current state of Earth's climate has no recorded precedent. The consequences of the sheer volume of anthropogenic ...

The department “Earth System Modelling” investigates the movement and chemical composition of atmospheric air and the associated energy and mass fluxes with the help of numerical simulation and ...

This reduces atmospheric drag, which is the force that naturally ... “satellite carrying capacity” of low Earth orbit. Their ...

satellite drag modeling, spacecraft gas-surface interactions, and small spacecraft systems design. His recent projects include: the design of assimilation schemes for specifying the space environment ...

Specifically, that decrease in density reduces “atmospheric drag,” or a force that pulls ... and contracts before expanding again. While modeling from the 1990s already showed that greenhouse ...

Their preliminary modeling showed that ... scenarios over the next century to investigate impacts on atmospheric density and drag. For each "shell," or altitude range of interest, they then ...
