NASA Atmospheric Scientist Dr. Caroline Dang analyzes particles in the atmosphere and compares them with particles collected from flight observations to better understand aerosols in Earth's atmosphere and how they interact with clouds and radiation.

Distinguished Professor of Environmental Science & Management at UC Santa Barbara speaks with Ph.D. candidate in the Hydrogeology program at the University of Nevada, Reno.

In this interview, Dr. Meloe S. Kacenelenbogen discusses her expertise in ‘aerosols,’ suspended particles in the atmosphere. These small particulates can affect air quality and human health and can also impact the Earth’s radiation balance. We also discuss why she...

Dr. Diana Gentry, a research scientist at NASA Ames Research Center, studies aerobiology (microbes in clouds), biodiversity, biomaterials, and biological systems. Diana describes herself as at the nexus of both science and engineering where she speaks both languages and translates...

Mei Zheng studies and teaches atmospheric science at Peking University. She’s passionate about training the next generation of scientists, and ensuring that everyone has access to clean air. “A teacher’s job is to encourage, inspire, and challenge students to do...

Paul Newman, Chief Scientist for Earth Science at NASA Goddard Space Flight Center and the co-chair to the Montreal Protocol, is one of the planet’s top ozone watchdogs – a self-described detective who looks for any chemicals which may deplete...

Dr. Matthew Johnson's research is in atmospheric chemistry, a branch of atmospheric science, which looks at the composition and chemistry of Earth's atmosphere, such as aerosols and trace gas emissions, and how particles may impact human health. Dr. Johnson's research...

Michael MacCracken, chief scientist with the Climate Institute came to Washington, DC supposedly for one year, to help ten different agencies involved in climate research to work better together. He stayed for nine years, becoming the liaison to Vice President...

Steve Montzka has been at NOAA for 28 years, working on atmospheric science, atmosphere chemistry, and trace gases in the atmosphere. He started there as a post-doc, drawn by the work he saw NOAA scientists doing on the hole in...

Dr. Laura Iraci is a research scientist in the Earth Sciences Division at NASA Ames, where she leads a group focusing on air and where human pollution goes. In this interview, we discuss her early interest in high school chemistry...

Richard Stolarski, research professor shares the journey of his involvement with the movement to address ozone depletion. He discusses how a multi-disciplinary team of scientists came together to heal the ozone layer, and how the world came together with the...

Dr. Charles Gatebe's research focus is on clouds aerosols, ecosystem structure and function, albedo, and feedbacks to climate. In this interview, we chat about his science journey pursuing science, starting with his interest in studying Kenya’s air pollution, and how...
