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

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]
Atmospheric 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.

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 ...

A framework for expanding aqueous chemistry in the Community Multiscale Air Quality (CMAQ) model version 5.1 [PDF]
Geoscientific Model Development, 2017 This paper describes the development and implementation of an extendable aqueous-phase chemistry option (AQCHEM − KMT(I)) for the Community Multiscale Air Quality (CMAQ) modeling system, version 5.1.

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 ...

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.

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.

Osmium: An Appraisal of Environmental Exposure [PDF]
Environmental Health Perspectives, 1974 In the U.S., the chief source of new osmium is copper refining, where this metal is produced as a byproduct. Probably less than 10% of the osmium in the original copper ore is recovered, and 1000-3000 oz troy of osmium is lost each year to the environment as the toxic, volatile tetroxide from copper smelters.

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.
