A recently published study uses both satellite and in situ observations of atmospheric methane to model methane sources, removals, and trends from 2010 to 2017.

Dr. Sally Ng, an atmospheric scientist funded by CPO's Atmospheric Chemistry Carbon Cycle and Climate (AC4) program, is featured in a NOAA Research "Meet Our Scientsits" profile as part of Women's History Month.

Recent research suggests a more active carbon dioxide (CO₂) cycle in high northern latitude ecosystems as a result of Arctic climate change.

As air pollution from vehicle emissions decline, the response of pollutants from other sources to temperature is becoming an important factor in high-aerosol and high-ozone events in the Los Angeles megacity region. 

The NOAA GeoXO Atmospheric Composition (AC) Town Hall will be held on April 29, 2021, from 12-4 pm EST to introduce the GeoXO mission to the AC community and share potential AC capabilities from this next-generation NOAA geostationary satellite system.
