Tracking dust around the globe

 

 

How far does dust travel–and why?

Traveling Saharan dust can make for beautiful sunsets and help fertilize the Amazon rainforest. But these tiny particles (no larger than 1/10th the width of a human hair) may also have an impact on global climate and weather patterns.

“My research has to do with how we monitor dust more effectively,” says Tsekeri. “Right now, we have data from ground-based instruments and satellites that we aren’t able to interpret correctly because we do not have realistic models for dust in terms of size and shape.”

Alexandra Tsekeri (National Observatory of Athens) was one of the scientific speaker at PRACEdays19.

Tsekeri and her colleagues have been granted high-performance computing (HPC) resources from PRACE (Partnership for Advanced Computing in Europe) and currently run simulation models on MareNostrum at Barcelona Supercomputing Center and ARIS, the Greek national supercomputer.
