Taming uncertainty in climate prediction

(PhysOrg.com) -- Uncertainty just became more certain. Atmospheric and computational researchers at Pacific Northwest National Laboratory used a new scientific approach called "uncertainty quantification," or UQ, that allowed ...

At 10, GRACE continues defying, and defining, gravity

(PhysOrg.com) -- Just as the lead characters in the popular Broadway musical "Wicked" sing about defying gravity, the low-Earth orbiting twin spacecraft of NASA's Gravity Recovery and Climate Experiment (GRACE) continue to ...

A finger to the wind

Like testing the wind direction before taking flight, researchers led by scientists at Pacific Northwest National Laboratory assessed the meteorological conditions during a large observational study of carbon-containing atmospheric ...
