PNAS Study Improves Representation of Dry Deposition in Climate and Air Quality Models

Atmospheric scientists, funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle and Climate (AC4) program, developed an improved method to represent the removal of aerosols from the atmosphere in climate and air quality models.

Urban Atmosphere in a Changing Climate: Chemistry, Carbon, and Composition

NOAA’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) Program is announcing nine new three-year projects in Fiscal Year 2020 (FY20) that aim to understand the chemical composition of the urban atmosphere across the United States. The competitively selected projects total $5.6 in grant awards.  Multiple linkages exist between air quality and climate change–none more so than in

Tracking fossil fuel emissions with carbon-14

Researchers, funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle, and Climate Program (AC4), have devised a breakthrough method for estimating national emissions of carbon dioxide from fossil fuels using ambient air samples and a well-known isotope of carbon that scientists have relied on for decades to date archaeological sites.
