An additional step toward comprehensive paleoclimate reanalyses

Hugues Goosse

Commentary— Although data assimilation in paleoclimatology has shown significant progress, the model data comparison step remains a limiting factor because paleoclimate (proxy) records have generally a complex response to both climatic and nonclimatic factors. In experiments performed in a controlled.... more

Wet Soils Elevate Nighttime Temperatures

Paul A. Dirmeyer, Editor, JAMES

Editors' Highlight— Soil moisture can elevate overnight temperatures, offsetting daytime cooling, especially over areas of strong land-atmosphere interactions. Using a conceptual model of the surface energy budget, Cheruy et al. [2017] demonstrate a noteworthy negative nocturnal feedback between soil.... more

How Do Clouds React to Regional Warming?

Sarah Witman, Freelance Writer

Research Spotlight— Researchers illuminate how and why cloud feedbacks depend on spatial patterns of global warming. Clouds play an important role in Earth’s global climate, both by reflecting the Sun’s radiation back out into space and by holding in thermal radiation. The extent to which clouds affect.... more

Improved Simulation of Gross Primary Productivity

Paul A. Dirmeyer, Editor, Journal of Advances in Modeling Earth Systems

Editor’s Highlight— A new model better explains seasonal variations in biomass. Diffuse solar radiation can increase light use efficiency in plant canopies compared to direct sunlight. This can impact terrestrial gross primary production (GPP). Yan et al. [2017] have developed a novel diffuse-fraction-based.... more

Incorporating microbial processes into earth system models

Editor’s Highlight—   Soils are the largest land-based pool of carbon. The decomposition of soil organic carbon to carbon dioxide by microbes plays a significant role as a biotic feedback to climate change. Despite decades of research, high uncertainty remains in the land-based climate change feedbacks.... more

Open-Source Tool Aims to Boost Confidence in Ice Sheet Models

Sarah Stanley, Freelance Writer

From Eos.org: Research Spotlights— The software could help strengthen ice sheet models to provide a better basis for policy decisions.  Massive ice sheets with layers built up over millions of years blanket most of Greenland and Antarctica. Due to climate change, these ice sheets have begun to melt.... more

Spatial scales of tropical rainfall in a changing climate

Editor’s Highlight—   This paper offers insights on spatial scales of rainfall and their mechanisms in a changing climate. The authors present results for changes in extreme precipitation in a superparameterized General Circulation Model (GCM) and how the changes differ between the GCM gridboxes and.... more

How to Find an Iceberg’s Breaking Point

Sarah Witman, Freelance Writer

From Eos.org: Research Spotlights— Researchers develop a mathematical method of modeling tabular icebergs, like the one that broke away from an Antarctic ice shelf earlier this year. Last month, an iceberg the size of Delaware calved, or broke away, from Larsen C, the fourth-largest ice shelf surrounding.... more
