The Journal of Geophysical Research is a peer-reviewed scientific journal published by the American Geophysical Union 80 times per year. It contains original research on the physical, chemical, and biological processes that contribute to the understanding of the Earth, Sun, and solar system. It has seven sections: A (Space Physics), B (Solid Earth), C (Oceans), D (Atmospheres), E (Planets), F (Earth Surface), and G (Biogeosciences). All current and back issues are available online for subscribers. The journal was originally named Terrestrial Magnetism by the American Geophysical Union s president Louis Agricola Bauer in 1896. It was entitled Terrestrial Magnetism and Atmospheric Electricity from 1899–1948. In 1980, three specialized sections were established: A: Space Physics, B: Solid Earth, and C: Oceans. Subsequently, further sections have been added: D: Atmospheres in 1984, E: Planets in 1991, F: Earth Surface in 2003, and G: Biogeosciences in 2005. The scopes of the current seven sections, published as separate issues, are: Each of the sections has one or more editors who are appointed by and serve at the pleasure of the President of the American Geophysical Union for terms of
NASA simulation portrays ozone intrusions from aloft
(Phys.org) —Outdoor enthusiasts in Colorado's Front Range are occasionally rewarded with remarkable visibility brought about by dry, clear air and wind. But it's what people in the mountainous U.S. West ...
Hunt for water intensifies—on two planets
(Phys.org) —Scientists are using a promising new theory to track down hidden water both on Earth – where fresh water is becoming dangerously scarce in some regions – and in the quest for life on the red planet, Mars.
Researchers find planet-sized space weather explosions at Venus
Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called ...
Drought affects the carbon cycle in Georgia blackwater rivers
(Phys.org) —Droughts might be affecting how Georgia's blackwater rivers process carbon, according to a new study led by an ecologist while he was at the University of Georgia. The results, which were published ...
Brown carbon works both sides of the climate equation
There is an atmospheric particle not satisfied with only a single role in the climate. The ambitious culprit? Brown carbon aerosol steps outside the box and acts to both warm and cool the climate. A brown ...
Nature can selectively buffer human-caused global warming
Can naturally occurring processes selectively buffer the full brunt of global warming caused by greenhouse gas emissions resulting from human activities?
Simulation of electron environment in space at 36,000 km
A spacecraft at near-Earth orbit is continuously bombarded by charged particles. Finnish Meteorological Institute has developed a unique model that simulates electron environment in the near-Earth space.
How habitable is Mars? A new view of the Viking experiments
Almost 40 years ago, two NASA probes on the surface of Mars scooped the soil in search of signs of microbes. The results that came back from the twin Viking missions were, to say the least, ambiguous. The ...
The tundra—a dark horse in planet Earth's greenhouse gas budget
There are huge amounts of organic carbon in the soil beneath the tundra that covers the northernmost woodless areas of the planet. New research findings from Aarhus University show that the tundra may become ...
Researchers use climate model to better understand electricity in the air
(Phys.org) —Electrical currents born from thunderstorms are able to flow through the atmosphere and around the globe, causing a detectable electrification of the air even in places with no thunderstorm ...
Algorithm finds missing phytoplankton in Southern Ocean
NASA satellites may have missed more than 50% of the phytoplankton in the Southern Ocean, making it far more difficult to estimate the carbon capture potential of this vast area of sea.
Online tool boosts ash cloud forecasts
A new online tool for predicting the amount of ash pumped into the atmosphere during a volcanic eruption has been made openly available to scientists around the world.
Disposal of Marcellus Shale fracking waste caused earthquakes in Ohio
Before January 2011, Youngstown, Ohio, had never had an earthquake since observations began in 1776. In December 2010, the Northstar 1 injection well came online, built to pump wastewater produced by hydraulic fracturing ...
Radio waves carry news of climate change
The ionosphere, one of the regions of the upper atmosphere, plays an important role in global communications. Ionized by solar radiation, this electricity-rich region is used for the transmission of long ...
Evidence for a Martian Ocean
(Phys.org) —Researchers at the California Institute of Technology (Caltech) have discovered evidence for an ancient delta on Mars where a river might once have emptied into a vast ocean.
