In recent decades, three major volcanic eruptions of different intensity have occurred (Mount Agung in 1963, El Chich oacute;n in 1982 and Mount Pinatubo in 1991), with reported...

Each spring, the climatological westerly winds of the Northern Hemisphere (NH) stratospheric polar vortex turn easterly as the stratospheric equator-to-pole temperature gradient...

We study UV spectra obtained with the SO82-B slit spectrograph on board SKYLAB to estimate the fine structure (FS) splitting of the Cl-like 3p(4)3d(4)D(5/2) and 3p(4)3d(4)D(7/2)...

This report provides a survey of a number of the currently accepted methods of shape preserving interpolation that have appeared in literature. In addition, the report presents...

Stratospheric aerosol intervention (SAI) is being explored for its potential to reduce greenhouse gas (GHG) induced climate damages. We assess the effectiveness of two SAI...

Stratospheric transit time distributions (age‐of‐air spectra) are estimated using time series of satellite water vapor (H 2 O) measurements from the Microwave Limb...

Generating accurate weather forecasts of planetary boundary layer (PBL) properties is challenging in many geographical regions, oftentimes due to complex topography or...

A new version of the Community Atmosphere Model (CAM) has been developed and released to the climate community. CAM Version 3 (CAM3) is an atmospheric general circulation model...

The Persistent Cold-Air Pool Study (PCAPS) was conducted in Utah's Salt Lake valley from 1 December 2010 to 7 February 2011. The field campaign's primary goal was to improve...

Mineral dust is an important aerosol in the atmosphere and is known to reduce snow albedo upon deposition. Model predictions of dust deposition events in snow covered mountain...

Air quality has become one of the most important environmental concerns for Delhi, India. In this perspective, we have developed a high-resolution air quality prediction system...

Recently it has been proposed that the phase delay associated with the radio signals propagating from GPS satellites to a ground-based GPS receiving station can be used to infer...

Motivated by recent discussions concerning differences of convective dynamics in polluted and pristine environments, the so-called convective invigoration in particular, this...

The key assumption underlying convection parameterizations is that rising plumes develop in a horizontally homogeneous environment. With this in mind, we investigate the impact...

At most latitudes, the seasonal cycle of zonal-mean surface air temperature is notably asymmetric: the length of the warming season is not equal to the length of the cooling...

A study was conducted to investigate the production history of Visqueen A balloon film and to develop information useful for future procurement, quality control, and design of...

Extreme heat is a major threat to human health worldwide. The COVID-19 pandemic, with its complexity and global reach, created unprecedented challenges for public health and...

The impact of the El Niño-Southern Oscillation (ENSO) on temperature extremes is examined in both observations and coupled climate model simulations. HadEX2, a newly developed...

Most of our understanding of the atmosphere is based on observations and their comparison with model simulations. In middle atmosphere studies it is common practice to use an...
