In this video from the NCSA Blue Waters Symposium, Patrick Reed from Cornell University presents: Collaborative Research: Petascale Design and Management of Satellite Assets to Advance Space Based Earth Science.

This project is a multi-institutional collaboration between Cornell University, The Aerospace Corporation, and Princeton University advancing a Petascale planning framework that is broadly applicable across space-based Earth observation systems design. 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.
