An analysis of two days of in situ observations of ice particle size spectra, in convectively generated cirrus, obtained during NASA's Tropical Composition, Cloud, and Climate...

Recent progress in computing and model development has initiated the era of global storm-resolving modeling, and with it the potential to transform weather and climate...

Plasmaspheric hiss plays an important role in controlling the overall structure and dynamics of the Earth's radiation belts. The interaction of plasmaspheric hiss with radiation...

Climate variability and weather phenomena can cause extremes and pose significant risk to society and ecosystems, making continued advances in our physical understanding of such...

Application of random sampling techniques to composite differences between 18 El Nino and 14 La Nina events observed since 1920 reveals considerable uncertainty in both the...

Scientists have observed large increases in melting on the Greenland Ice Sheet in recent decades. But what is happening in Antarctica? Temperature increases during the past...

On 15 May 1999, a storm intercept team from the University of Oklahoma collected high-resolution, W-band Doppler radar data in a tornado near Stockton, Kansas. Thirty-five...

Observations of stellar activity cycles provide an opportunity to study magnetic dynamos under many different physical conditions. Space-based asteroseismology missions will...

Meltwater runoff in the catchment area containing Chhota Shigri glacier (Western Himalaya) is simulated for the period 1951-2099. The applied mass-balance model is forced by...

n this work, the magnetic variations simulated by the NCAR thermosphere-ionosphere-electrodynamics general circulation model (TIE-GCM) in the vicinity of the magnetic equator...

This paper describes approximations that have been found useful in calculating the transmission of molecular gases in planetary atmospheres. This includes the use of band models...

It has been established that observed local and regional levels of secondary organic aerosols (SOA) in polluted areas cannot be explained by the oxidation and partitioning of...

The atmospheric limb sounding technique based on the Global Positioning System (GPS) has been shown to be accurate and of very high vertical resolution. The fact that the GPS...

This paper presents a learning-based, physics-aware soil moisture (SM) retrieval algorithm for NASA's Cyclone Global Navigation Satellite System (CYGNSS) mission. The goal of...

The diurnal cycle of warm-season precipitation in the Rocky Mountains and adjacent Great Plains of the United States is examined using a numerical modeling framework designed to...

Science and technology always have been interdependent, but never more so than with today's highly instrumented data collection practices. We report on a long-term study of...

Some parameterizations of gravity wave mean flow forcing in global circulation models (GCMs) add realism by describing wave generation by tropospheric convection. Because the...

The goal of the Chemistry-Climate Model Validation (CCMVal) activity is to improve understanding of chemistry-climate models (CCMs) through process-oriented evaluation and to...

Estimates suggest that over 4 gigatons per year of carbon dioxide (Gt-CO2 year(-1)) be removed from the atmosphere by 2050 to meet international climate goals. One strategy for...
