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.

The report captures two days of plenary presentations as well as small breakout group discussions, and provides recommendations for future research directions for ESSM and partners.

Better understanding of this ozone sink is essential for improved modeling and prediction of air pollution, ecosystem health, and climate.

In honor of Women's History Month, NOAA is highlighting a few of its female scientists and funded researchers who are making significant strides in the climate sciences and other science fields. The following interview is with Dr. Lucy Hutyra, an Associate Professor in the Department of Earth and Environment at Boston University and CPO Atmospheric Chemistry, Carbon Cycle and Climate (AC4) Program-funded scientist. 

The principal investigator meeting was an opportunity to complement the atmospheric composition sessions at the JPSS/GOES-R Summit, and continue AC4 efforts to leverage existing meetings to hold principal investigator meetings.
