Independent lines of research on urbanization, urban areas, and carbon have advanced our understanding of some of the processes through which energy and land uses affect carbon....

The size-dependence of the linear depolarisation ratio of mineral dust aerosols is investigated. Laboratory measurements on 131 different aerosol samples with varying size...

Unique Fe lidar observations in May 2014 at McMurdo, combined with Aura-Microwave Limb Sounder measurements, lead to a new discovery that the amplitudes of 4 day and 2.5 day...

Using airborne data from several recent field projects, the authors have taken another look at the properties of exponential ice particle size distributions (PSDs) when the PSDs...

Some of the most intense convective storms on Earth initiate near the Sierras de Cordoba mountain range in Argentina. The goal of the RELAMPAGO field campaign was to observe...

We explore the use of machine learning (ML) techniques, namely, regression trees (RT), for the purpose of aviation turbulence forecasting at upper levels [20-45 kft (;6-14 km)...

Ionospheric storms can have important effects on radio communications and navigation systems. Storm time ionospheric predictions have the potential to form part of effective...

Three-dimensional maps of the distribution of coronal electron density can now be computed with two radial functions in the series expansion for the density. This report...

General circulation models (GCMs) are essential for projecting future climate; however, despite the rapid advances in their ability to simulate the climate system at increasing...

A preliminary investigation into the impact of dropsonde observations from the Global Hawk (GH) on tropical and extratropical forecasts is performed using the National Centers...

A limited area model (LAM) intercomparison study is conducted based on a tropical monsoonal deep convection case observed during the Tropical Warm Pool - International Cloud...

This study examines factors shaping individuals' preferences for use of tornado shelters in public and private facilities during the COVID-19 pandemic, utilizing over 6000...

A chemical ionization mass spectrometer was used to measure BrO and HOBr+Br-2 over the Tropical West Pacific Ocean within the altitude range of 1 to 15km, during the CONvective...

Physically based models facilitate understanding of seasonal snow processes but require meteorological forcing data beyond air temperature and precipitation (e.g., wind,...

At high latitudes, changes in soil moisture could alter soil temperatures independently of air temperature changes by interacting with the snow thermal rectifier. The authors...

Ice-nucleating particles (INPs) are rare atmospheric aerosols that initiate primary ice formation, but accurately simulating their concentrations and variability in large-scale...

Research flights with the National Center for Atmospheric Research (NCAR) C-130 airborne laboratory were conducted over the equatorial ocean during the Pacific Atmospheric...

Among the physical processes controlling aerosol vertical profiles, in-cloud wet removal is of utmost importance while its representation in global climate models (GCMs) is...

Anthropogenically forced changes in ocean biogeochemistry are underway and critical for the ocean carbon sink and marine habitat. Detecting such changes in ocean biogeochemistry...

Wildfires are a major source of gas-phase ammonia (NH3) to the atmosphere. Quantifying the evolution and fate of this NH3 is important to understanding the formation of...
