Urban regions emit a large fraction of anthropogenic emissions of greenhouse gases (GHG) such as carbon dioxide (CO2) and methane (CH4) that contribute to modern-day climate...

The Community Atmosphere Model, version 4 (CAM4), was released as part of the Community Climate System Model, version 4 (CCSM4). The finite volume (FV) dynamical core is now the...

The simulated winds within the urban canopy of landfalling tropical cyclones are sensitive to the representation of the planetary boundary and urban canopy layers in numerical...

So far studies of the effect of geomagnetic storms on thermospheric density and satellite orbits have been mainly focused on severe storm events caused by Coronal Mass Ejections...

The impacts of transported background (TBG) pollutants on western US ozone (O ₃) distributions in summer 2008 are studied using the multi-scale Sulfur Transport and dEposition...

Specified dynamics (SD) schemes relax the circulation in climate models toward a reference meteorology to simulate historical variability. These simulations are widely used to...

We use the extensive set of aircraft and ground-based observations from the NSF/National Center for Atmospheric Research (NCAR) and State of Colorado Front Range Air Pollution...

Regression-based detection and attribution methods continue to take a central role in the study of climate change and its causes. Here we propose a novel Bayesian hierarchical...

The recent development of whole atmosphere models that extend from the surface to the upper thermosphere represents a significant advance in modeling capabilities of the...

Geoengineering methods could potentially offset aspects of greenhouse gas-driven climate change. However, before embarking on any such strategy, a comprehensive understanding of...

Recent progress is reviewed in the understanding of convective interaction with water vapor and changes associated with water vapor in warmer climates. Progress includes new...

International Group on Attribution of Climate-Related Events (ACE); Boulder, Colorado, 26 January 2009; Climate change is likely to be manifested on societies around the world...

This study represents an attempt to apply Large-Eddy Simulation (LES) resolution to simulate deep tropical convection in near equilibrium for 24 hours over an area of about 205...

We present an approach to estimate the feedback from large-scale thawing of permafrost soils using a simplified, data-constrained model that combines three elements: soil carbon...

Diurnal restratification of the ocean surface boundary layer (OSBL) represents a competition between mixing of the OSBL and solar heating. Langmuir turbulence (LT) is a mixing...

The FLUXNET2015 dataset provides ecosystem-scale data on CO2, water, and energy exchange between the biosphere and the atmosphere, and other meteorological and biological...

The purpose of this note is to provide "quick look" satellite retrievals of cloud properties for the FIRE Marine Stratus IFO, June 29- July 19, 1987. It is hoped that this quick...

To investigate gravity wave (GW) perturbations in the midlatitude mesopause region during boreal equinox, 433 h of continuous Na lidar full diurnal cycle temperature...

As a first step toward coupled ocean-atmosphere data assimilation, a parallelized ensemble filter is implemented in a new stochastic hybrid coupled model. The model consists of...

The impact. of surface emissions on the zonal structure of tropical tropospheric ozone and carbon monoxide is investigated for November 2004 using satellite observations, in-...
