A new satellite that last week began gathering data from the Earth's atmosphere could be a key tool in unraveling just how much effect the reflectivity of clouds and tiny particles called aerosols are having on the planet's ...
Atmospheric scientists have developed simple, physics-based equations that address some of the limitations of current methods for representing cloud formation in global climate models – important because of increased aerosol ...
Low clouds populate the first two kilometers of the atmosphere. Cumuliform clouds heap high and are made from columns of fast-rising air. Stratiform are sheet-like and show little vertical air movement.
The favored refrain of climate deniers and those who oppose climate policies is that "the science is not settled." To some degree, this is true. Climate scientists are still uncertain about a number of phenomena. But it is ...
Human activity is changing atmospheric chemistry—even in remote places—that could alter how and when clouds form.
In weather terms, convection is the process of conveying heat and moisture upward through a turbulent atmosphere. From there, convection forms clouds—mostly puffy, rain-free shallow cumuli. But others evolve into towering ...
The 2019/20 wildfires in Australia transported more smoke into the atmosphere than observed ever before anywhere in the world. In the so-called Black Summer, three times as many particles reached high air layers as in the ...
NASA is beginning work on a new satellite mission that will extend critical climate measurements of Earth's oceans and atmosphere and advance studies of the impact of environmental changes on ocean health, fisheries and the ...
Taking part in the largest U.S. air quality field project in decades, the National Center for Atmospheric Research (NCAR) is working with partners to study pollution in the Southeast. The study looks at the impact of chemical ...
Arizona State University researchers have made a breakthrough in understanding the effect on climate change of a key component of urban pollution. The discovery could lead to more accurate forecasting of possible global-warming ...
