Ozone pollution in the Southeast US involves complex chemistry driven by emissions of anthropogenic nitrogen oxide radicals (NOx = NO + NO2) and biogenic isoprene. Model...

The Year of Polar Prediction in the Southern Hemisphere (YOPP-SH) held seven targeted observing periods (TOPs) during the 2022 austral winter to enhance atmospheric...

This report describes the background, numerical methods, and results of a theoretical and experimental study of the pressure waves generated by a sudden release of energy along...

Projections of the sea level contribution from the Greenland and Antarctic ice sheets (GrIS and AIS) rely on atmospheric and oceanic drivers obtained from climate models. The...

A bulk three-moment representation for rain microphysics is developed and implemented in the Predicted Particle Properties (P3) microphysics scheme. In addition, a new...

We study the response of the thermosphere and ionosphere to the dissipation of gravity waves (GWs) excited by a deep convective plume on 1 October 2005 at 52.5 degrees W, 15.0...

The Global Energy and Water Cycle Experiment (GEWEX) Cloud System Study (GCSS) was created in 1992. As described by Browning et al. (1993, p. 387), "The focus of GCSS is on...

This study addresses the land-atmospheric coupling strength by using long-term AmeriFlux data from a wide range of land covers and climate regimes to reconstitute the surface...

Long-time solar researcher Patrick McIntosh died on 16 October 2016 after developing symptoms of Alzheimer's disease about 2010.

Localization and hybridization are two methods used in ensemble data assimilation to improve the accuracy of sample covariances. It is shown in this paper that it is beneficial...

Sensitivity of 0-12 -h warm-season precipitation forecasts to atmospheric initial conditions, including those from different large-scale model analyses and from rapid cycled...

Hydrology/water management and electricity generation projections have been modeled separately, but there has been little effort in intentionally and explicitly linking the two...

Co-occurrence of high relative humidity levels and high temperatures can increase human discomfort, thereby affecting electricity requirements for space cooling. While relative...

This paper describes the flight control software of the wave-front correction system that flew on the 2009 science flight of the Sunrise balloon telescope. The software...

In September 2020, Western North America was impacted by a highly anomalous meteorological event. Over the Pacific Northwest, strong and dry easterly winds exceeded historically...

Far ultraviolet observations of Earth's dayglow from the National Aeronautics and Space Administration (NASA) Global-scale Observations of the Limb and Disk (GOLD) mission...

The early Eocene (similar to 56-48 Myr ago) is characterized by high CO2 estimates (1,200-2,500 ppmv) and elevated global temperatures (similar to 10 degrees C-16 degrees C...

As the pressure to address the climate crisis builds, scientists must walk the line between research and activism. This was apparent at the 2019 United Nations (UN) Framework...

Multiscale modeling of a diurnal cycle of real-world conditions is presented for the first time, validated using data from the CWEX-13 field experiment. Dynamical downscaling...

We present a global chemical data assimilation system using a global atmosphere model, the Community Atmosphere Model (CAM3) with simplified chemistry and the Data Assimilation...
