Organic aerosols (OAs) comprise a significant fraction of the Arctic aerosol mass, helping modulate the radiative balance of the Arctic atmosphere. A new study sheds light on composition and sources of OAs. While OAs in the Arctic are primarily influenced by anthropogenic emissions, mostly from Eurasia in winter, natural emissions largely take over in summer.
Better understanding of how ozone, an air pollutant and greenhouse gas, is removed is essential for improved modeling and prediction of air pollution, ecosystem health, and climate.
New research published in The Proceeding of the Royal Society - Biological Sciences provides new insights on the threat ocean warming poses on coral growth in Mesoamerican barrier reefs. The ...
In many parts of North America, a fluctuating air-pressure pattern that enhances or blocks the storm-steering jet stream, called the Arctic Oscillation (AO), explains more variability in the ...
El Niño-Southern Oscillation contributes to global climate variability, with significant impacts on the North American continent. New research uses a combination of paleoclimatic and instrumental data to more reliably quantify the impacts of variability in this interconnected system.
City and county officials and residents don’t always understand what hazard mitigation is or why it benefits their community, including how it may help with obtaining FEMA funding. NOAA has provided a resource focused on the benefits of hazard mitigation in Oklahoma.
At ground level, the mobile lab can often measure emissions closer to the fire source, and it can be used at night when flying an aircraft near a wildfire may be hazardous. Lab results show that wildfire emissions vary based on whether the fire is flaming or smoldering.
In early June 2021, the National Integrated Drought Information System (NIDIS) released the Southern Plains Drought Early Warning System (DEWS) 2021–2025 Strategic Action Plan. The Plan is designed to set priorities and suggest measurable actions that can create value in this drought-prone region, with the ultimate goal of improving stakeholder resilience during times of drought.
