In contrast to the general stratospheric ozone recovery following international agreements, recent observations show an ongoing net ozone depletion in the tropical lower...

This study examines the spatial variability of ozone fluxes over flat heterogeneous terrain consisting of a patchwork of irrigated and nonirrigated surfaces. Fluxes of ozone and...

Open questions about the modulation of near-surface trace gas variability by stratosphere-troposphere tracer transport complicate efforts to identify anthropogenic sources of...

The effects of tuning of length-scale and observation-error on heavy rainfall forecasts are investigated. Length scale and observation error are tuned based on observation minus...

The impacts of transported background (TBG) pollutants on western US ozone (O
₃) distributions in summer 2008 are studied using the multi-scale Sulfur Transport and...

The "reliability ensemble averaging" (REA) method for calculating average, uncertainty range, and a measure of reliability of simulated climate changes at the subcontinental...

Commercial aircraft flying at supersonic speeds in the lower stratosphere are being discussed once again after a hiatus of almost 20 years. Potential environmental effects from...

African easterly waves (AEWs) have important impacts on rainfall, drought, and the development of tropical cyclones in the Atlantic basin. However, the interannual variability...

Lake surface conditions are critical for representing lake‐atmosphere interactions in numerical weather prediction. The Community Land Model's 1‐D lake component...

The characteristics of tropical mesoscale convective systems (MCSs) simulated with a finer-resolution (similar to 50 km) version of the Geophysical Fluid Dynamics Laboratory...

The Houston-Galveston-Brazoria urban area contains industrial petrochemical sources that emit volatile organic compounds and nitrogen oxides, resulting in rapid and efficient...

A new remote sensing retrieval of ice cloud microphysics has been developed for use with millimeter-wave radar from ground-, air-, or space-based sensors. Developed from an...

The relationship between gravity wave momentum fluxes and local wind speed is investigated for oceanic regions at high southern latitudes during austral spring. The motivation...

The enhancement of the stratospheric aerosol layer by volcanic eruptions induces a complex set of responses causing global and regional climate effects on a broad range of...

Aura Microwave Limb Sounder (MLS) version 2.2 (V2.2) and CloudSat R04 (release 4) ice water content (IWC) and partial - column ice water path (pIWP) measurements are analyzed...

The North American Coordinated Regional climate Downscaling Experiment ­(NA-CORDEX) in partnership with Ouranos, the National Center for Atmospheric Research, Iowa State...

Recent decades have seen strong trends in hydroclimate over the American Southwest, with major river basins such as the Rio Grande exhibiting intermittent drought and declining...

Reduced daytime upward ExB drifts and weakened fountain effects in equatorial ionosphere have been frequently observed during the initial stage of solar flares. The cause of...

Atmospheric iodine causes tropospheric ozone depletion and aerosol formation, both of which have significant climate impacts, and is an essential dietary element for humans....

We performed simulations of the atmosphere-ionosphere response to the solar eclipse of 21 August 2017 using the Whole Atmosphere Community Climate Model-eXtended (WACCM-X v....
