In this study, the fifth-generation Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model (MM5) with three-dimensional variational data...

Cloud microphysical processes occur at the smallest end of scales among cloud-related processes and thus must be parameterized not only in large-scale global circulation models...

The emission, dispersion, and photochemistry of isoprene (C5H8) and related chemical species in the convective boundary layer (CBL) during sunlit daytime were studied over a...

Episodic air quality degradation due to particles occurs in multiple cities in central and southern Chile during the austral winter reaching levels up to 300-800 µg/m3 hourly...

This technical note summarizes metrics that have been defined to assess the quality of forecasts of solar irradiance and solar power production forecasting. A set of six base...

Estimation of uncertainties (random error statistics) of radio occultation (RO) observations is important for their effective assimilation in numerical weather prediction (NWP)...

The co-occurrence of heat waves and pollution events and the resulting high mortality rates emphasize the importance of the co-occurrence of pollution and temperature extremes....

An approximate analytic expression is derived for the ratio lambda of the ascent rate of moist deep convective thermals and the maximum vertical velocity within them; lambda is...

We present the frequency redistribution function for a polarized three-term atom of the Lambda-type in the collisionless regime, and we specialize it to the case where both the...

Projected changes to the severity, frequency and duration of long-term droughts for 47 watersheds in the Canadian Prairie provinces, as well as uncertainties associated with the...

The serial ensemble square root filter (EnSRF) typically assumes observation errors to be uncorrelated when assimilating the observations one at a time. This assumption causes...

The climatology of the spatial structure functions of velocity and temperature for various altitudes (pressure levels) and latitude bands is constructed from the global...

Aerosol-cloud interactions (ACI) are the consequence of perturbed aerosols affecting cloud drop and crystal number, with corresponding microphysical and radiative effects. ACI...

The study postulates that crop rooting depth representation plays a vital role in simulating soil-crop-atmospheric interactions. Rooting depth determines the water access for...

The ability to measure sesquiterpenes (SQT; C₁₠H₂₄) by a Proton-Transfer-Reaction Mass Spectrometer (PTR-MS) was investigated. SQT calibration standards were prepared by...

The second phase of the North American Monsoon Experiment (NAME) Model Assessment Project (NAMAP2) was carried out to provide a coordinated set of simulations from global and...

Land models require evaluation in order to understand results and guide future development. Examining functional relationships between model variables can provide insight into...

High-resolution atmospheric models are powerful tools for hurricane track and intensity predictions. Although using high resolution contributes to better representation of...

Mediterranean-type climates are defined by temperate, wet winters, and hot or warm dry summers and exist at the western edges of five continents in locations determined by the...

Society's progress along the four corners of prepare, absorb, respond and adapt resilience square is uneven, in spite of our understanding of the foundational science and a...
