“We have made substantial progress towards three transformative contributions: (1) we are the first team to formally link high-resolution astrodynamics design and coordination of space assets with their Earth science impacts within a Petascale “many-objective” global optimization framework, (2) we have successfully completed the largest Monte Carlo simulation experiment for evaluating the required satellite frequencies and coverage to maintain acceptable global forecasts of terrestrial hydrology (especially in poorer countries), and (3) we have evaluated the limitations and vulnerabilities of the full suite of current satellite precipitation missions including the recently approved Global Precipitation Measurement (GPM) mission. This work illustrates the tradeoffs and consequences of a collapse in the current portfolio of rainfall missions.
Researchers are using supercomputers at to detect previously unknown channels of slow-moving seismic waves in Earth’s upper mantle. This discovery helps to explain how “hotspot volcanoes”—the kind that give birth to island chains like Hawaii and Tahiti—come to exist.
Researchers at ETH Zurich and the University of Leeds are using supercomputers to learn why the Earth’s magnetic field moves gradually westward.
