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. 

Using data sampled from wildfires across the US in the 2018 Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption, and Nitrogen (WE-CAN) campaign, this study is the first to quantify ice nucleating particles within wildfire smoke plumes in the free troposphere.
