Contribution of natural geologic seepage to methane emissions

Editor’s Highlight—   The process of natural geologic seepage has received little attention from the atmospheric science community despite its potential contribution to climate change. This paper considers one particular methane seep, the La Brea tar pits, located within a city park in Los Angeles..... more

Higher accuracy global ozone data

Editor’s Highlight—   This paper presents the results of a major, international effort to homogenize and reprocess ozonesonde data for consistency. This large data set is used by many satellite and modeling groups. The results in this paper demonstrate the value of the reprocessing, and for those who’ve.... more

New approach to geoengineering simulations is significant step forward

Blog— Using a sophisticated computer model, scientists have demonstrated for the first time that a new research approach to geoengineering could potentially be used to limit Earth’s warming to a specific target while reducing some of the risks and concerns identified in past studies, including uneven.... more

Ocean Showers Power the Global Electric Circuit

Emily Underwood, Freelance Writer

From Research Spotlights— Satellite measurements confirm hundred-year-old observations collected by boat.  In 1909, a wood-hulled yacht called the Carnegie sailed roughly 480,000 kilometers around the world’s oceans, gathering measurements of atmospheric electricity known collectively as the.... more

Methane Leaks May Make Natural Gas Worse than Coal for Climate

Emily Underwood, Freelance Writer

From Research Spotlights—  Estimates of methane emissions from fracking in northern West Virginia and southwestern Pennsylvania suggest natural gas may have a bigger impact on climate than previously thought. Because burning natural gas produces about half as much carbon dioxide (CO2) per unit.... more

How the Micrometeorology of Alpine Forests Affects Snowmelt

Jenny Lunn, Contributing Writer

From Research Spotlights— A field study in the Swiss Alps showed considerable spatial and temporal variability in forest air and surface temperatures, with implications for snowmelt models.  Warming temperatures in spring herald the melting of snow in mountains and higher-latitude regions..... more

The Microphysics of Squall Lines

Sarah Stanley, Freelance Writer

From Research Spotlights— Scientists tracked the distribution of raindrops of different sizes as a row of thunderstorms formed by a cold front developed and intensified over eastern China. As a cold front advances, a row of thunderstorms known as a squall line may form along or ahead of its.... more

New Data Record Extends History of Global Air Pollution

Sarah Witman, Freelance Writer

From Research Spotlights— Researchers extend long-term aerosol records to the past 40 years by combining two existing algorithms to process satellite data over both land and sea.  The World Health Organization calls air pollution the invisible killer, as it can be difficult to trace, yet is.... more

Researchers take on atmospheric effects of Arctic snowmelt

Blog—  Researchers at the University of Alaska Fairbanks’ Geophysical Institute are exploring the changing chemistry of the Arctic’s atmosphere to help answer the question of what happens as snow and ice begin to melt. The research is concerned with the Arctic’s reactive bromine season, the period of.... more

A coupled snow-atmosphere modeling study

Editor’s Highlight—   Snow-atmosphere interactions is an important but under-appreciated field. Snow is a critical natural water reservoir yet we do not have a good understanding of what controls its distribution, particularly in alpine environments where it is most important. This paper presents a.... more
