A new study funded by CVP finds unexpected long-range links between aerosol particle source, especially smoke, and atmospheric processes including cloud formation and radiative properties.

Nitrogen reacts with oxygen and other chemical compounds to form atmospheric oxides, which significantly impact the chemical composition of our atmosphere, human and environmental health, and broader climate processes. These gases can be produced by a range of natural and anthropogenic sources including fossil fuel combustion and wildfires. The atmospheric chemistry research community has developed new methods to track the emission sources of these gases and their key chemical reactions by analyzing the stable isotopes of nitrogen and oxygen in the gas compounds. However, there is a lack of a well-established method to simultaneously differentiate and quantify the concentration and isotopic composition of multiple groups of nitrogen oxides.

A newly published Science article highlights the work of NOAA’s Earth’s Radiation Budget Initiative, addressing the basic research needed to understand solar radiation management.

Model analysis in a recent CVP-funded study sheds new light on relationships between weather and climate in West Africa and large-scale atmospheric patterns.

A recent study supported by AC4 uses drought index as a tool to explain the trends of particulate matter (PM) air pollution and its association with wildfires across the US.
