Cosmic Muons Reveal the Land Hidden Under Ice

Jenny Lunn, Contributing Writer

From Research Spotlights— Scientists accurately map the shape of the bedrock beneath a glacier using a new technique.  The land surface under a glacier is sculpted and shaped by the ice passing over it. Data about the shape of the bedrock yield information crucial to understanding erosional.... more

Antenna Towers Attract Additional Lightning Strikes

Sarah Witman, Freelance Writer

From Research Spotlights— Atmospheric scientists evaluate the influence of human-made structures on lightning data.  Over the last 30 years, a proliferation of new technologies (especially cell phones) has increased the number of antenna towers in the United States more than threefold. Advancements.... more

Warmer temps cause decline in key runoff measure

Blog— Since the mid-1980s, the percentage of precipitation that becomes streamflow in the Upper Rio Grande watershed has fallen more steeply than at any point in at least 445 years, according to a new study led by the National Center for Atmospheric Research (NCAR). While this decline was driven in.... more

Ice particles in Earth’s atmosphere create bright flashes seen from space

Press Release— One million miles from Earth, a NASA camera is capturing unexpected flashes of light reflecting off our planet. The homeward-facing instrument on NOAA’s Deep Space Climate Observatory, or DSCOVR, launched in 2015, caught hundreds of these flashes over the span of a year. NASA’s Earth.... more

Fine Particle pH during Severe Haze Episodes in Northern China

Editor’s Highlight— The authors of this paper conduct calculations of fine mode aerosol acidity (pH) in northern China using a thermodynamic model constrained by observations of atmospheric acid and bases. They find that even under the highest levels of ammonia possible, the aerosol pH is less than.... more

Paris 1.5°C target may be smashed by 2026

Blog— Global temperatures could break through the 1.5°C barrier negotiated at the Paris conference as early as 2026 if a slow-moving, natural climate driver known as the Interdecadal Pacific Oscillation (IPO) has, as suspected, moved into a positive phase. New research published in Geophysical Research.... more

High-altitude aircraft data may help improve climate models

Blog— Sulfur dioxide released from volcanoes or power plants causes acid rain and leads to particles that play a role in breaking down the protective ozone layer high in the atmosphere. But those particles also reflect sunlight away from Earth, leading some to propose that people could inject sulfur.... more

Early Results: Juno at Jupiter 

Early results from Juno's mission at Jupiter including approach to Jupiter and the first perijove pass (PJ1). Juno's scientific objectives include the study of Jupiter's interior, atmosphere and polar magnetosphere with the goal of understanding Jupiter's origin, formation and evolution. This collection of papers provides early results from Juno's measurements of the gravity and magnetic fields, deep atmospheric microwave sounding, infrared, visible and ultraviolet images/spectra and an array of fields and particles instruments as well as context for the early results with respect to current theory and models of Jupiter's formation and evolution. Topics include both Juno - Jupiter related theoretical models and data analysis as well as collaborative observations made from Earth based assets.
