This study proposes a novel structural self-organizing map (S-SOM) algorithm for synoptic weather typing. A novel feature of the S-SOM compared with traditional SOMs is its...

Hydrogen chloride (HCl) and hydrogen fluoride (HF) are respectively the main chlorine and fluorine reservoirs in the Earth's stratosphere. Their buildup resulted from the...

Recent increases in computing power mean that atmospheric models for numerical weather prediction are now able to operate at grid spacings of the order of a few hundred meters,...

This study examines two factors impacting initiation of moist deep convection: free-tropospheric environmental relative humidity (phi(E)) and horizontal scale of subcloud ascent...

South America is a large continent situated mostly in the Southern Hemisphere (SH) with complex topography and diverse emissions sources. However, the atmospheric chemistry of...

This study investigates the aerosol effects on the development of an idealized three-dimensional supercell storm, focusing on storm morphology and precipitation during a quasi...

The Overflow Parameterization (OFP) for the ocean component of the Community Climate System Model (CCSM) is presented. The ocean component is based on the Parallel Ocean Program...

Estimated external radiative forcings, model results, and proxy-based climate reconstructions have been used over the past several decades to improve our understanding of the...

Current models are too noisy to predict climate usefully on decadal timescales, but two-stage post-processing of model outputs greatly improves predictions of decadal variations...

We report an earthward moving ion-scale flux rope embedded within the trailing edge of a hot flow anomaly (HFA) observed by the Magnetospheric Multiscale satellite constellation...

The Adelie Land coastal region of Antarctica is one of the most prominent cyclogenesis regions in the Southern Hemisphere, and is adjacent to the continent's most intense...

The Atmospheric Chemistry Experiment (ACE) mission was launched in August 2003 to sound the atmosphere by solar occultation. Carbon monoxide (CO), a good tracer of pollution...

This Technical Note presents the observations made during this effort in the interval 3-17 June 1983. As far as possible, daily observations made with the Mark-Ill kcoronameter...

Marine Ecosystems and Climate: Modeling and Analysis of Observed Variability; Boulder, Colorado, 2-14 August 2009; Despite evidence of significant impacts from climate change,...

We investigated the diurnal variation of tropospheric nitrogen dioxide (NO2) over a cluster of high emission thermal power plants (HETPPs) in India using two products from...

The COronal Solar Magnetism Observatory (COSMO) is a proposed facility with unique capabilities for magnetic field measurements in the solar atmosphere and corona to increase...

Different meteor radars at low latitudes observed abnormally strong westward mesospheric winds around the March Equinox of 2023, that is, during the first phase of the...

The National Science Foundation's Daniel K. Inouye Solar Telescope (DKIST) will revolutionize our ability to measure, understand, and model the basic physical processes that...

Isoprene and its first and second generation photochemical products, methyl vinyl ketone (MVK), methacrolein (MACR), and peroxymethacrylic nitric anhydride (MPAN), were measured...

The Earth System Model Evaluation Tool (ESMValTool) is a community diagnostics and performance metrics tool designed to improve comprehensive and routine evaluation of Earth...
