Global trends in tropospheric nitrogen dioxide (NO2) have changed dramatically in the past decade. Here, we investigate tropospheric NO2 variabilities over United States,...

The air quality in large urbanized regions represents one of the major threats to the public and the ecosystems health. A number of harmful compounds emitted to the atmosphere...

The effect of dry and wet deposition of semi-volatile organic compounds (SVOCs) in the gas phase on the concentrations of secondary organic aerosol (SOA) is reassessed using...

Tropical upper-tropospheric troughs (TUTTs), transient summertime disturbances over the Pacific and Atlantic Oceans, are also observed to frequently occur in the North American...

We present an analysis of a 39-year record of continuous atmospheric CO₂ observations made at Baring Head, New Zealand, filtered for steady background CO₂ mole fractions during...

This paper estimates marine boundary layer height (MBLH) over the western North Pacific (WNP) based on Global Positioning System Radio Occultation (GPS-RO) profiles from the...

Biogenic isoprene fluxes were measured onboard the CIRPAS Twin Otter aircraft as part of the California Airborne Biogenic volatile organic compound (BVOC) Emission Research in...

Although hot spells and heat waves are considered extreme meteorological phenomena, the statistical theory of extreme values has only rarely, if ever, been applied. To address...

Measurements from the High Resolution Dynamics Limb Sounder (HIRDLS) on NASA's Aura satellite are used to quantify gravity wave momentum fluxes generated from monsoon regions...

This study investigates the effects of resolved deep convection on tropical rainfall and its multi-scale variability. A series of aquaplanet simulations are analyzed using the...

Ionospheric outflow plays an important role in the mass coupling between the ionosphere and the coupled solar wind-magnetosphere system. Previous modeling studies have shown...

Cross-shore transport of larvae, pollutants, and sediment between the surf zone and the inner shelf is important for coastal water quality and ecosystems. Rip currents are known...

Wildfires pose a significant risk to human livelihoods and are a substantial health hazard due to emissions of toxic smoke. Previous studies have shown that climate change,...

Venus Express (VEX) has been monitoring key nightglow emissions and thermal features (O₂ IR nightglow, NO UV nightglow, and nightside temperatures) which contribute to a...

The adequate representation of the dominant intra-seasonal and synoptic scale variability in the tropics, characterized by the Madden-Julian oscillation (MJO) and convectively...

Decaying Hall magnetohydrodynamic (HMHD) turbulence is studied using three-dimensional (3D) direct numerical simulations with grids up to 768(3) points and two different types...

The following report summarizes recent results of balloon-borne observations separately for the various disciplines: infrared astronomy, ultraviolet astronomy, X-ray astronomy,...

Modern computer architectures reward added computation if it reduces algorithmic dependence, reduces data movement, increases accuracy/robustness, and improves memory accesses....

Using an interactive aerosol-climate model we find that absorbing anthropogenic aerosols, whether coexisting with scattering aerosols or not, can significantly affect the Indian...

A multifluid version of the Lyon-Fedder-Mobarry global simulation model has been used to investigate the effects of outflowing ionospheric O⁺ on the magnetosphere-ionosphere...
