Ariel Stein

Tracking pollutants in the atmosphere with a world-renowned model

One versatile model can track airborne dust from the Sahara Desert, forecast smoke dispersal from wildfires, and predict the spread of radiation through the atmosphere from nuclear accidents. Dr. Ariel Stein and his NOAA colleagues maintain and continually improve this model.

New chemical discovered during historic airborne research mission to spur reexamination of marine sulfur cycle and climate models

The discovery of a novel sulfur compound during a 2017 NASA airborne research campaign will likely spur a scientific reassessment of a fundamental marine chemical cycle which drives the formation of oceanic clouds that play a key role in moderating climate.  “People thought the sulfur budget was well understood,” said NOAA scientist Patricia Quinn, who was not involved in the study. “This throws a kink in the whole works.”

A Year Locked in Ice

Picture a calm, sunny day at a tropical beach. You look out at the ocean and in the distance a flotilla of small white clouds sails close to the waves. It’s ideal weather and typical of many days in the tropical Atlantic. However, scientists don’t fully understand how these ubiquitous clouds (a type of “shallow convective cloud”) form and impact the ocean, and it represents one of the largest uncertainties in predicting climate change.

ABOUT US

Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
