NOAA Climate Program Office’s ERB, AC4 And CVP Programs Award $3 Million For New Applications Of Satellite Data To Aerosol Research

Dr. Daniel Cziczo, professor and head of Purdue Earth, Atmospheric, and Planetary Sciences, and his research team have been awarded a National Oceanic & Atmospheric Administration Climate Program Office grant. This grant will be used for research combining aerosol composition and optical properties measurements from the AEROMMA airborne field mission to evaluate and improve satellite data products.

Unwrapping Uranus and its icy secrets: What NASA would learn from a mission to a wild world

THE CONVERSATION — "Many in the space community – like me – are urging NASA to launch a robotic spacecraft to explore Uranus. Indeed, the 2023 decadal survey of planetary scientists ranked such a journey as the single highest priority for a new NASA flagship mission. This time, the spacecraft would not simply fly by Uranus on its way somewhere else, as Voyager 2 did. Instead, the probe would spend years orbiting and studying the planet, its 27 moons and its 13 rings," explains Dr. Mike Sori, of Purdue EAPS, in a piece he penned for The Conversation.

Scientists look at pyrite isotopes on the ocean floor in a whole new light

Beneath the ocean floor, layers of sediment tell a story of hundreds of millions of years of environmental change. However, this story has taken a surprising turn. Scientists for the past several decades assumed that sulfur isotopes in pyrite (commonly referred to as “fool’s gold”) could be used to transcribe the history of the oxidation state of the Earth’s oceans. But in a shocking twist, scientists have learned that local conditions on the sea floor are what really controls pyrite sulfur isotopes. “We found that bulk pyrite sulfur isotopes are dominantly controlled by local conditions on the seafloor, such as the rate of sediment accumulation, porosity and permeability, and organic matter concentration,” says Dr. Roger Bryant from Purdue University College of Science. “This discovery should fundamentally change how bulk pyrite sulfur isotopes are used by the scientific community.”
