A simple lightning assimilation technique for improving retrospective WRF simulations

open access: yesJournal of Advances in Modeling Earth Systems, 2016
Convective rainfall is often a large source of error in retrospective modeling applications. In particular, positive rainfall biases commonly exist during summer months due to overactive convective parameterizations. In this study, lightning assimilation

Long-term trends in the ambient PM2.5- and O3-related mortality burdens in the United States under emission reductions from 1990 to 2010 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Concentrations of both fine particulate matter (PM2.5) and ozone (O3) in the United States (US) have decreased significantly since 1990, mainly because of air quality regulations.

Modeling stratospheric intrusion and trans-Pacific transport on tropospheric ozone using hemispheric CMAQ during April 2010 – Part 2: Examination of emission impacts based on the higher-order decoupled direct method [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
The state-of-the-science Community Multiscale Air Quality (CMAQ) modeling system, which has recently been extended for hemispheric-scale modeling applications (referred to as H-CMAQ), is applied to study the trans-Pacific transport, a phenomenon ...

Reporting back environmental exposure data and free choice learning. [PDF]

open access: yes, 2016
Reporting data back to study participants is increasingly being integrated into exposure and biomonitoring studies. Informal science learning opportunities are valuable in environmental health literacy efforts and report back efforts are filling an ...

Distribution and Causes of Global Forest Fragmentation

open access: yesEcology and Society, 2003
Because human land uses tend to expand over time, forests that share a high proportion of their borders with anthropogenic uses are at higher risk of further degradation than forests that share a high proportion of their borders with non-forest, natural ...

Environmental contaminants exposure and preterm birth: a systematic review [PDF]

open access: yes, 2019
Preterm birth is an obstetric condition associated with a high risk of infant mortality and morbidities in both the neonatal period and later in life, which has also a significant public health impact because it carries an important societal economic ...

Development and evaluation of a physics‐based windblown dust emission scheme implemented in the CMAQ modeling system

open access: yesJournal of Advances in Modeling Earth Systems, 2017
A new windblown dust emission treatment was incorporated in the Community Multiscale Air Quality (CMAQ) modeling system. This new model treatment has been built upon previously developed physics‐based parameterization schemes from the literature.

Global-Scale Patterns of Forest Fragmentation

open access: yesEcology and Society, 2000
We report an analysis of forest fragmentation based on 1-km resolution land-cover maps for the globe. Measurements in analysis windows from 81 km 2 (9 x 9 pixels, "small" scale) to 59,049 km 2 (243 x 243 pixels, "large" scale) were used to characterize ...

Thermal reaction products and formation pathways of two monoterpenes under in situ thermal desorption conditions that mimic vaping coil temperatures

open access: yesScientific Reports, 2023
Vaping has become more popular and different brands and types of vaping devices have rapidly emerged. However, little is known about the potential health risks of human inhalation exposures to the volatile chemicals in the vapour, which includes both ...

Bayesian Multiple Index Models for Environmental Mixtures [PDF]

open access: yes, 2021
An important goal of environmental health research is to assess the risk posed by mixtures of environmental exposures. Two popular classes of models for mixtures analyses are response-surface methods and exposure-index methods. Response-surface methods estimate high-dimensional surfaces and are thus highly flexible but difficult to interpret.
