Evaluation of OCO-2 small-scale XCO2 variability using lidar retrievals from the ACT-America flight campaign
With eight 1.25 x 3 kilometer footprints across its swath and nearly 1 million observations of column-mean carbon dioxide concentration (XCO2) per day, the Orbiting Carbon Observatory (OCO-2) presents exciting possibilities ... -
Climate and health impacts of particulate matter from residential combustion sources in developing countries
Globally, close to 2.8 billion people lack access to clean cooking technology, while 1.8 billion people lack access to electricity altogether. As a means to generate energy for residential tasks, it is common in many ... -
Impact of upper tropospheric temperatures and radiation on idealized tropical cyclones, The
Potential intensity (PI) theory predicts that the tropopause temperature acts as a powerful constraint on tropical cyclone (TC) intensity and structure. The physical mechanisms by which the upper tropospheric thermal ... -
Atmospheric reactive nitrogen in Rocky Mountain National Park
The Front Range urban corridor in Colorado, located east of Rocky Mountain National Park (RMNP), includes a variety of urban sources of nitrogen oxides, while high emissions of ammonia are found in agricultural sources on ... -
Objective analysis of extreme precipitation events in diverse geographic regions
Extreme precipitation events are a focus of much research in the atmospheric science community today. These events are extraordinarily impactful to society, damaging critical infrastructure and in the worst cases taking ... -
Micrometeorological studies of a beef feedlot, dairy, and grassland : measurements of ammonia, methane, and energy balance closure
Ammonia emissions from concentrated animal feeding operations (CAFOs; most of which are beef feedlots) near the Colorado Front Range are suspected to be a large regional input of reactive nitrogen which has been found to ... -
Investigating contributions to elevated surface ozone in the Colorado Front Range during summer 2015
Tropospheric ozone (O3) is a significant pollutant in the Colorado Front Range. The northern Front Range metropolitan area (NFRMA) has exceeded the U.S. EPA national ambient air quality standard for O3 since 2008. While ... -
Lightning channel locations, LNOx production, and advection in anomalous and normal polarity thunderstorms
Tropospheric ozone is a powerful greenhouse gas and OH precursor, thus understanding its sources is important. Its production is also widely studied in atmospheric science today as global climate modelers attempt to estimate ... -
Investigations of the uncertainties associated with HID algorithms and guiding input to a novel, synthetic polarimetric radar simulator
A methodology for model evaluation against observations is presented. With the advent of polarimetric radars, the need to produce simulated radar observables from model has also become apparent, in order to directly compare ... -
Volatile organic compound concentrations and the impacts of future oil and natural gas development in the Colorado Northern Front Range
Recent advances in unconventional extraction of oil and natural gas (O&NG) have caused an increase in the number of wells in the Colorado Northern Front Range (CNFR) which has doubled Colorado's natural gas production over ... -
Influence of the Madden-Julian Oscillation and Caribbean Low-Level Jet on east Pacific easterly waves
The east Pacific warm pool exhibits basic state variability associated with the Madden-Julian Oscillation (MJO) and Caribbean Low-Level Jet (CLLJ), which affects the development of easterly waves (EWs). This study compares ... -
Cold pool processes in different environments
Cold pools are localized regions of dense air near Earth's surface. They form in association with precipitating clouds in many environments ranging from moist tropical to semi-arid continental conditions, and they play ... -
Unconventional eyewall replacement cycle of Hurricane Ophelia (2005), The
One of the mechanisms proposed for the spin-up of the tropical cyclone (TC) mean tangential circulation is the convergence of absolute angular momentum above the boundary layer. This mechanism is important for the outer ... -
Cloud process information from a fleet of small satellites : synthetic retrievals using an optimal estimation algorithm
The great importance of clouds in understanding atmospheric phenomena is widely recognized, yet faithful representations of cloud and precipitation processes in models at nearly all scales remain elusive. In order to ... -
Role of inner-core and boundary layer dynamics on tropical cyclone structure and intensification, The
Inner-core and boundary layer dynamics play a vital role in the tropical cyclone life cycle. This study makes use of analytical solutions and numerical models to gain insight into the role of dynamical processes involved ... -
Using remotely sensed fluorescence and soil moisture to better understand the seasonal cycle of tropical grasslands
Seasonal grasslands account for a large area of Earth's land cover. Annual and seasonal changes in these grasslands have profound impacts on Earth's carbon, energy, and water cycles. In tropical grasslands, growth is ... -

Towards understanding the role of natural variability in climate change
Natural variability plays a large role in determining surface climate on local and regional scales. Understanding the role of natural variability is crucial for accurately assessing and attributing climate trends, both ... -
Analysis of total lightning characteristics in tornadic storms : preparing for the capabilities of the GLM, An
Numerous studies have found that severe weather is often preceded by a rapid increase in the total lightning flash rate. This rapid increase results from numerous intra-cloud flashes forming around the periphery of an ... -
Microphysical, dynamical, and lightning processes associated with anomalous charge structures in isolated convection
Internal storm charge structures are linked to storm microphysics and dynamics. This study leverages available radar-based microphysical and dynamical information from recent field campaigns to investigate the processes ...
