NOAA research links human-caused CO2 emissions to dissolving sea snail shells off U.S. West Coast NOAA research links human-caused CO2 emissions to dissolving sea snail shells off U.S. West Coast For the first time, NOAA and partner scientists have connected the concentration of human-caused carbon dioxide in waters off the U.S. Pacific coast to the dissolving of shells of microscopic marine sea snails called pteropods.

Scientists test a new tool to improve local precipitation forecasts Scientists test a new tool to improve local precipitation forecasts A new weather forecasting tool could soon find itself part of the day-to-day operations of NOAA's National Weather Service (NWS). The instrument, called Atmospheric Emitted Radiance Interferometer, or AERI, measures temperature, water vapor and trace gases (like ozone, carbon monoxide and methane) in the lowest layer of Earth’s atmosphere, the troposphere. Now, an AERI project led by Tim Wagner, a scientist with NOAA’s Cooperative Institute for Meteorological Satellite Studies (CIMSS) at the University of Wisconsin–Madison, has received funding through NOAA’s Joint Technology Transfer Program.

Study shows ocean acidification is two-front assault on coral reefs Study shows ocean acidification is two-front assault on coral reefs Scientists studying coral reefs in volcanically acidified water of the southwestern Pacific Ocean measured a net loss of coral reef skeletons due to increased bio-erosion, according to new research by NOAA, the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) and Australian scientists.

Q&A: Is Arctic warming fueling severe winter weather in the mid-latitudes? Q&A: Is Arctic warming fueling severe winter weather in the mid-latitudes? We caught up with James Overland, oceanographer at NOAA’s Pacific Marine Environmental Lab, to hear about his latest research on whether Arctic warming is fueling more severe winter weather in the mid-latitudes, the temperate zone of the Earth between the tropics and the Arctic, and the part of the United States where most Americans live.

Antarctic ozone hole about average in 2016 Antarctic ozone hole about average in 2016 Results are consistent with expectations, scientists say The hole in the Earth’s ozone layer that forms over Antarctica each September grew to about 8.9 million square miles in 2016 before starting to recover, according to scientists from NOAA and NASA who monitor the annual phenomenon.

Atmospheric Rivers: What are they and how does NOAA study them? 11Jan2023 Read more You may have heard of atmospheric rivers in the news lately due to the intense rainfall and flooding along the U.S. West Coast. These naturally occurring air currents can bring both severe disruption and great benefit through the heavy rain and mountain snows that contribute to regional water supply. NOAA studies atmospheric rivers to improve forecasting capabilities as well as to improve our understanding of atmospheric river impacts on communities and the physical environment. Read more
One facility makes a big contribution to Salt Lake’s winter brown cloud 25Jan2023 Read more The 2.4 million people who live along Utah’s Wasatch Front experience some of the most severe winter particulate matter air pollution in the nation. Now, analysis of measurements taken during NOAA research flights in 2017 indicates that emissions from a single source, a magnesium refinery, may be responsible for a significant fraction of the fine particles that form the dense winter brown clouds that hang over Salt Lake City.

When volcanoes roar: protecting the public and tracking long-term climate impacts 5Jan2023 Read more 2022 was a busy year for volcanic eruptions with Hawaii's Mauna Loa and Kilaeau erupting simultaneously, along with Mount Semeru, Indonesia and the Hunga undersea volcano in Tonga. While the United States Geological Survey is the primary agency that monitors volcanic activity in the United States, the National Oceanic and Atmospheric Administration (NOAA) oversees safety systems for tsunamis and other volcano-related threats, as well as studies the impact of volcanic gasses on our global climate.
