Biomass burning (BB) is a large source of primary and secondary organic aerosols (POA and SOA). This study addresses the physical and chemical evolution of BB organic aerosols....

A small, isolated, short-lived cumulus congestus was studied using primarily a10 cm radar, a cloud penetration with an instrumented sailplane, and time-lapse photography froman...

Ionospheric currents are driven by several different physical processes and exhibit complex spatial and temporal structure. Magnetic field measurements of ionospheric sources...

Multiyear climate predictions provide climate outlooks from years to a decade in advance. As multiyear temperature predictions become more mainstream and skillful, guidance is...

The most destructive and deadly wildfires in US history were also fast. Using satellite data, we analyzed the daily growth rates of more than 60,000 fires from 2001 to 2020...

Extreme droughts are a major determinant of ecosystem disturbance that impacts plant communities and feeds back into climate change through changes in plant functioning....

Arctic climate encompasses multiple feedbacks, the most important of which is the ice-albedo feedback. Enhanced Arctic changes, first recognized in the nineteenth century,...

Airborne measurements of methane (CH₄) and carbon dioxide (CO₂) were taken over the rice growing region of California's Sacramento Valley in the late spring of 2010 and...

Idealized general circulation models (GCMs) suggest global-mean precipitation ceases to increase with warming in hot climates because evaporation is limited by the available...

We study the variations of the topside ionospheric ion density measured by Defense Meteorological Satellite Program satellites during the intense magnetic storm on 7-10 November...

We study electron injection and energization by bursty bulk flows (BBFs), by tracing electron trajectories using magnetohydrodynamic (MHD) field output from the Lyon-Fedder-...

The "solar-stellar connection" began as a relatively small field of research focused on understanding the processes that generate magnetic fields in stars and sometimes lead to...

Dehydration at the tropical cold point tropopause primarily controls the entry value of water vapor to the stratosphere, with additional (uncertain) contributions from...

Climate models predict Antarctic precipitation to increase during the 21st century, but their present day Antarctic precipitation differs. A model-independent climatology of the...

This report comprises translations of three papers by Max Margules on atmospheric oscillations, namely "Luftbewegungen in einer rotierenden Spharoidschale bei zonaler...

One of the main goals of the Tropical Composition, Cloud and Climate Coupling Experiment (TC⁴) during July and August 2007 was to gain a better understanding of the formation...

The ozone budget inside the middle stratospheric polar vortex (24-36 km) during the 2002-2003 Arctic winter is studied by analyzing Michelson Interferometer for Passive...

In this study, we use multi-instrument observations (all-sky imager (ASI), global navigation satellite system (GPS) receivers, digisonde) to study the interaction of nighttime...

The hydroclimate response to volcanic eruptions depends both on volcanically induced changes to the hydrologic cycle and on teleconnections with the El Niño–Southern...

Tropospheric ozone is a major air pollutant and greenhouse gas. It is also the primary precursor of OH, the main tropospheric oxidant. Global atmospheric chemistry models show...
