New research from NOAA finds that fragrant personal care products – the stuff that makes you smell good – are now responsible for a significant amount of the ozone pollution known as smog that plagues major urban areas.

From warmer ocean temperatures to longer and more intense droughts and heat waves, climate change is affecting our entire planet. Scientists at NOAA have long worked to track, understand and predict how climate change is progressing and impacting ecosystems, communities and economies.

NOAA and NIST have installed a Doppler lidar instrument to an existing weather station on top of the Department of Commerce’s Herbert Clark Hoover Building in Washington, D.C. to measure wind flow and turbulence in the lowest part of the atmosphere for a research project studying greenhouse gas emissions in the Capitol area.

Launching uncrewed systems to monitor climate and ecosystem changes in the U.S. Arctic, sequencing the genome for endangered marine species, and improving weather forecasts with advances in regional models — these are just a few of NOAA’s scientific achievements in 2020. The newly released 2020 NOAA Science Report highlights the ways these accomplishments — and many more — provide the foundation for vital services that Americans use every day.

The giant methane cloud spotted by satellite over the U.S. Southwest that made national headlines in 2014 wasn’t a persistent, undiscovered “hotspot” as first thought, but the result of a nightly atmospheric condition and topography that trapped industrial and natural emissions of the potent greenhouse gas near the ground in the basin overnight, according to new research published in the journal Elementa by CIRES and NOAA.

The study evaluated all of the aviation industry’s contributing factors to climate change, including emissions of carbon dioxide and nitrogen oxide, and the effect of contrails and contrail cirrus – short-lived clouds created in jet engine exhaust plumes at aircraft cruise altitudes that reflect sunlight during the day and trap heat trying to escape at night.
