Plasma irregularities in the ionosphere induce scintillation of radio signals. Radio occultation (RO) observations of the Global Navigation Satellite Systems (GNSS) signals from...

The high-resolution Whole Atmosphere Community Climate Model with thermosphere/ionosphere extension (WACCM-X) is used to study the impacts of gravity waves (GWs) on the...

The impact of very short-lived (VSL) halogenated source species on the ozone layer and surface erythemal ultraviolet radiation (UVERY) is investigated in the context of geo-...

Plant response to elevated CO2 concentration is known to increase leaf-level water-use efficiency through a reduction in stomatal opening. Recent studies have emphasized that...

Airborne vertically profiling Doppler radar data and output from a similar to 1-km-grid-resolution numerical simulation are used to examine how relatively small-scale terrain...

A meteoric sulfur input function and a sulfur ion chemistry scheme have been incorporated into a chemistry-climate model, in order to study the speciation of sulfur between the...

Future climate projections from Earth system models (ESMs) typically focus on the timescale of this century. We use a set of five ESMs and one Earth system model of intermediate...

The Canopy Horizontal Array Turbulence Study (CHATS) took place in spring 2007 and is the third in the series of Horizontal Array Turbulence Study (HATS) experiments. The HATS...

The Red Sea, home to the second-longest coral reef system in the world, is a vital resource for the Kingdom of Saudi Arabia. The Red Sea provides 90% of the Kingdom's potable...

Boreal summer intraseasonal oscillation (BSISO) is a primary source of predictability for summertime weather and climate on the subseasonal-to-seasonal (S2S) time scale. Using...

Climate models often underestimate the magnitude of extreme precipitation. We compare the performance of a high-resolution (∼0.25°) time-slice atmospheric simulation...

The hydroxyl radical (OH) is the primary daytime oxidant in the troposphere and provides the main loss mechanism for many pollutants and greenhouse gases, including methane...

The prediction skill for precipitation anomalies in late spring and summer months-a significant component of extreme climate events-has remained stubbornly low for years. This...

Phase 6 of the Coupled-Model Intercomparison Project (CMIP6) is the first in which a significant number of models include a well-resolved stratosphere. Changes in equatorial...

Each spring, the climatological westerly winds of the Northern Hemisphere (NH) stratospheric polar vortex turn easterly as the stratospheric equator-to-pole temperature gradient...

Land reclamation has occurred extensively worldwide to accommodate urbanization and economic development, especially in developing countries like China. However, we have a...

This study assesses the benefit of convective-scale data assimilation (DA) for model initialization using well-known functional relationships between lightning flash rate and...

Recent advances in seasonal to interannual hydroclimate predictions provide an opportunity for developing a proactive approach toward water management. This motivated a recent...

Simulations of stratospheric aerosol geoengineering have typically considered injections at aconstant rate over the entire year. However, the seasonal variability of both...

To assess current capabilities for measuring flow within the atmospheric boundary layer, including within wind farms, the U.S. Department of Energy sponsored the eXperimental...
