FROM THE EDITOR IN CHIEF

I am thrilled to announce that the first issue of AGU Advances, AGU's new flagship journal, is now online. AGU Advances is a highly selective, gold open-access journal that publishes seminal research across the Earth and space sciences and related interdisciplinary fields. This includes full-length research articles that advance our science, and commentaries that discuss recent scientific results or trends and put them in context for a broader audience. Our editorial team also highlights important research published in Earth and space science, and provides additional editorial content.

The research papers and associated content included in this first issue provide a great demonstration of the breadth of new research being published in Earth and space science, as well as excellent examples of the kinds of research papers and commentaries this influential journal will publish. —Susan Trumbore

COMMENTARIES

Why Does Ocean Warming Pattern Matter?

Ocean warming patterns are critical to climate science given their role in determining regional climate changes and modulating how much the globe may warm with elevated CO2 levels. Xie

Slow Slip By Any Other Name

Earth's faults slip most catastrophically as earthquakes. The rise of geodesy reveals an array of slower slip events, meaning faults are nearly always active. Are these behaviors really so different? Jolivet & Frank

RESEARCH ARTICLES

Skywatchers Spy Rippling Waves in the Northern Lights

Not to be outdone by the discovery of STEVE sub-auroral emissions last year, citizen scientists across Scandinavia reveal dune-shaped optical features, a new atmospheric phenomenon. Palmroth et al.

Quantifying Aerosol Effects on Climate Using Ship Track Clouds

A new methodology for measuring how human emissions influence cloud properties and radiative forcing developed by reconstructing cloud fields in maritime shipping lanes. Diamond et al.

Toward Forecasting Crop Productivity and Carbon Flux Anomalies

Quantifying reductions in U.S. Midwest crop productivity and carbon uptake due to 2019 flooding using combined satellite observations of solar-induced chlorophyll fluorescence and atmospheric CO2. Yin et al.

FEATURED AGU SPECIAL COLLECTION

Southern Ocean Clouds, Aerosols, Precipitation and Radiation

This joint collection between Geophysical Research Letters and JGR-Atmospheres seeks papers that use observations and models at a variety of spatial and temporal scales to advance the understanding on climate models challenged by uncertainties and biases in simulating Southern Ocean clouds, aerosols, precipitation and radiation.

EDITORS' PICKS FROM OTHER JOURNALS

SPACE PHYSICS

Earth's magnetic field traps charged particles in the radiation belts and, along with electric and magnetic field perturbations, transports and energizes them. Lejosne [2019] revisits the 55-year-old model of radial diffusion that describes this motion and compares it with present widely-used models, revealing important assumptions and errors that must be resolved for further progress in understanding radiation belt dynamics. —Mary Hudson

ENVIRONMENTAL GOVERNANCE

The Amazon forest hosts tremendous biodiversity, stores huge stocks of carbon, and regulates the region's water cycle. Following a special symposium at AGU's 2019 Fall Meeting, Bustamante [2020] provides compelling data on how science-based satellite monitoring, along with effective policy enforcement, reduced Amazon deforestation rates from 2004 to 2014. Now, the science and the policy enforcement are now under political attack. —Eric Davidson

CLIMATE DYNAMICS

Turbulent weather patterns in the atmosphere and ocean transport heat from low to high latitude. Gallet and Ferrari [2020] present a scaling theory that quantitatively predicts this heat transport as a function of the large-scale flow characteristics and bottom friction. It recognizes that weather patterns are characterized by coherent vortices and is a rare example of a successful scaling theory for a fully turbulent flow. —Paola Rizzoli

CORE-MANTLE BOUNDARY

Over the past 10 years, evidence of core-mantle interaction has trickled out slowly in the form of elemental ratios, like Fe/Mn, Os-isotopes but most convincingly from W-isotopes, as the core has an unradiogenic W isotopic composition compared to the silicate Earth. Mundl-Petermeier et al. [2020] argue that the ultra low velocity zones at the core-mantle boundary are the locations for core-mantle interaction, but more importantly make clear that core-mantle interaction is required to explain the geochemical signals, an important step forward in understanding mantle dynamics. —Vincent Salters
