Technical challenges and solutions in representing lakes when using WRF in downscaling applications [PDF]

Geoscientific Model Development, 2015
The Weather Research and Forecasting (WRF) model is commonly used to make high-resolution future projections of regional climate by downscaling global climate model (GCM) outputs.

The genome as a record of environmental exposure [PDF]

Mutagenesis, 2015
Whole genome sequencing of human tumours has revealed distinct patterns of mutation that hint at the causative origins of cancer. Experimental investigations of the mutations and mutation spectra induced by environmental mutagens have traditionally focused on single genes.

A simple lightning assimilation technique for improving retrospective WRF simulations

Journal 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

Distribution and Causes of Global Forest Fragmentation

Ecology 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 Exposure and Leptospirosis, Peru

Emerging Infectious Diseases, 2004
Human infection by leptospires has highly variable clinical manifestations, which range from subclinical infection to fulminant disease. We conducted a population-based, cross-sectional seroepidemiologic study in Peru to determine potential relationships of environmental context to human exposure to Leptospira and disease associated with seroconversion.

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

Journal 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

Ecology 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

Scientific 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 ...

Biomarkers of environmental benzene exposure. [PDF]

Environmental Health Perspectives, 1996
Environmental exposures to benzene result in increases in body burden that are reflected in various biomarkers of exposure, including benzene in exhaled breath, benzene in blood and urinary trans-trans-muconic acid and S-phenylmercapturic acid. A review of the literature indicates that these biomarkers can be used to distinguish populations with ...
