The community Noah land-surface model (Noah LSM) has been modified to couple with a photosynthesis-transpiration scheme (GEM) to estimate the deposition velocity (V d) for air...

Although the societal impact of a weather event increases with the rarity of the event, our current ability to assess extreme events and their impacts is limited by not only...

A model intercomparison activity was inspired by the large suite of observations of atmospheric composition made during the International Polar Year (2008) in the Arctic. Nine...

The angle μ between the geomagnetic dipole axis and the geocentric solar magnetospheric (GSM) zaxis, sometimes called the “dipole tilt,” varies as a function of UT and season....

Phosphorus contained in atmospheric mineral dust aerosol originating from Africa fertilizes tropical forests in Amazonia. However, the mechanisms influencing this nutrient...

Disastrous bushfires during the last months of 2019 and January 2020 affected Australia, raising the question to what extent the risk of these fires was exacerbated by...

A better understanding of multiscale interactions within the Madden-Julian oscillation (MJO), including momentum exchanges, is critical for improved MJO prediction skill. In...

Scenarios are key tools in analyses of global environmental change. Often they consist of quantitative and qualitative components, where the qualitative aspects are expressed in...

Understanding the cooling effect of recent volcanoes is of particular interest in the context of the post-2000 slowing of the rate of global warming. Satellite observations of...

As an effort toward improving climate model--component performance and accuracy, an atmospheric-component climate model has been developed, entitled the Spectral Element...

Using the CAM-chem Model, we simulate the response of chemical species in the free troposphere to scenarios of primary pollutant emission reductions during the COVID-19...

Aerosol hygroscopicity describes the ability of a particle to take up water and form a cloud droplet. Modeling studies have shown sensitivity of precipitation-producing cloud...

Sulfur dioxide (SO2) is emitted in large quantities from coal‐burning power plants and leads to various harmful health and environmental effects. In this study, we use plume...

There is great interest in understanding how the thermosphere-ionosphere system responds to geomagnetic storms. New insights are possible using the new generation of fully...

Widespread streamflow droughts can pose substantially greater societal challenges than spatially less extensive events because of the complex realities of trans-regional water...

Carbon isotopes in the ocean are frequently used as paleoclimate proxies and as present-day geochemical ocean tracers. In order to allow a more direct comparison of climate...

Historical reanalyses that span more than a century are needed for a wide range of studies, from understanding large-scale climate trends to diagnosing the impacts of individual...

In this study, the dynamical processes contributing to warm-core meso-β-scale vortex formation associated with the 8 May 2009 "super derecho" are examined utilizing two...

Projections of future climate change play a fundamental role in improving understanding of the climate system as well as characterizing societal risks and response options. The...

The long-term accurate specification of the Earth's ionospheric states is crucial to scientific research and applications in the space weather community. In the current work, a...
