The direct and semi-direct radiative effects of biomass burning aerosols (BBAs) are investigated over southern Africa and the southeastern Atlantic during the Aerosols,...

The NASA Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment (ACTIVATE) produced a unique dataset for research into aerosol-cloud-meteorology...

As part of the United States' contribution to the International Trans-Antarctic Scientific Expedition (ITASE), a network of precisely dated and highly resolved ice cores was...

Acetone is one of the most abundant oxygenated volatile organic compounds (VOCs) in the atmosphere. The oceans impose a strong control on atmospheric acetone, yet the oceanic...

The Madden-Julian oscillation poses great challenges to our understanding and prediction of tropical convection and the large-scale circulation. Several internationally...

In 2006, NASA led a field campaign to investigate the factors that control the fate of African easterly waves (AEWs) moving westward into the tropical Atlantic Ocean. Aircraft...

The MOPITT (Measurements of Pollution in the Troposphere) satellite instrument has been making nearly continuous observations of atmospheric carbon monoxide (CO) since 2000....

Thermosphere densities from the CHAMP and GRACE satellites are utilized, for the first time, to study the recovery of the thermosphere as a function of latitude during the...

Many studies have shown the deficiencies of the extended Kalman filter (EKF), even though it has become a standard technique used in nonlinear estimation. In the EKF method, the...

Results from the fully and biogeochemically coupled simulations in which CO2 increases at a rate of 1 % yr(-1) (1pctCO2) from its preindustrial value are analyzed to quantify...

This NOAA-funded project aims to explore and assess (1) the public's awareness and understanding concerning storm surge and storm surge information, and (2) whether the NWS...

Previous investigations of ionospheric storm-enhanced density (SED) and tongue of ionization (TOI) focused mostly on the behavior of TOI during intense geomagnetic storms....

Fast and accurate large‐eddy simulation (LES) of the atmospheric boundary layer plays a crucial role in advancing wind energy research. Long‐duration wind farm...

Qualifying examinations are an important milestone in geoscience graduate programs, but students with marginalized identities are disproportionately lost from graduate programs...

Coastal communities in the Southeast U.S.A. face increasing risks from storm surge, extreme rainfall, and rising sea levels, highlighting the need for effective monitoring and...

The Northern Hemisphere and tropical circulation response to interannual variability in Arctic stratospheric ozone is analyzed in a set of the latest model simulations archived...

The Thermosphere Ionosphere Mesosphere Electrodynamics General Circulation Model (TIME-GCM) is used to simulate the quasi-two-day wave (QTDW) modulation of the ionospheric...

This study compares the distribution of surface climate trends over the Southern Ocean in austral summer between 1979-2011 and 1950-1978, using a wide variety of data sets...

Aerosols produced in the lower stratosphere can brighten the planet and counteract some of the effects of global warming. We explore scenarios in which the amount of precursors...

Drought is a function of both natural and human influences, but fully characterizing the interactions between human and natural influences on drought remains challenging. To...
