Microplastics (MPs) are an emerging class of pollutants in air, soil and especially in all aquatic environments. Secondary MPs are generated in the environment during...

The response of precipitation extremes (PEs) to global warming is found to be nonlinear in Community Earth System Model version 1 (CESM1) and other global climate models...

Atmospheric acidity is increasingly determined by carbon dioxide and organic acids1,2,3. Among the latter, formic acid facilitates the nucleation of cloud droplets4 and...

This study evaluates the performance of four bulk-type microphysics schemes, Weather Research and Forecasting (WRF) double-moment 6-class (WDM6), WRF double-moment 7-class...

A function that approximates atmospheric tidal behavior in the polar regions is described. This function is fitted to multistation radar measurements of wind in the mesosphere...

Extratropical cyclones in winter and their characteristics are investigated in depth for the Atlantic European region, as they are responsible for a significant part of the...

The Geophysical Fluid Dynamics Laboratory (GFDL) has developed a new variable-resolution global model with the ability to represent convective-scale features that serves as a...

Polar mesospheric clouds (PMC), or noctilucent clouds, can be observed over high latitudes with the naked eye from the ground or from space near the summer solstice. PMC are...

This work uses a WRF numerical simulation from 1960 to 2005 performed at a high horizontal resolution (2 km) to analyze the surface wind variability over a complex terrain...

The Andenes specular meteor radar shows meteor trail diffusion rates increasing on average by about 10 % at times and locations where a lidar observes noctilucent clouds (NLCs)....

Stratospheric Sounding Units (SSU) on the NOAA operational satellites have been the main source of near-global temperature trend data above the lower stratosphere. They have...

Results from simulations performed for the Atmospheric Chemistry and Climate Modeling Intercomparison Project (ACCMIP) are analysed to examine how OH and methane lifetime may...

Biomass burning is a major source of light-absorbing organic aerosol (brown carbon), but its composition, chemical evolution, and lifetime are not well known. We measured water-...

Urban land surface processes need to be represented to inform future urban climate and building energy projections. Here, the single layer urban canopy model Town Energy Balance...

Continuous measurements of hygroscopicity and volatility of atmospheric aerosol particles of 4 - 10 nm diameter were conducted with a nanometer tandem differential mobility...

Production of new particles over forests is an important source of cloud condensation nuclei that can affect climate. While such particle formation events have been widely...

Ensemble simulations are run with a global coupled climate model employing five forcing agents that influence the time evolution of globally averaged surface air temperature...

The western United States was affected by several megadroughts during the last 1200 years, most prominently during the Medieval Climate Anomaly (MCA; 800 to 1300 CE). A null...

The U.S.-Taiwan Partnership for International Research and Education (PIRE) "Building Extreme Weather Resiliency through Improved Weather and Climate Prediction and Emergency...
