These guidelines provide a framework for integrating air quality and climate change considerations into policy development by assessing the interactions between measures to reduce air pollutants and greenhouse gas emissions. They are intended to support policymakers and practitioners in identifying strategies that maximize synergies between clean air and climate objectives while minimizing trade-o...

This document provides guidance to help air quality agencies develop, operate, and evaluate ozone and PM2.5 forecasting programs.  This guidance document provides: • Background information about ozone and PM2.5 and the weather's effect on these pollutants. • A list of how air quality forecasts are currently used. • A summary and evaluation of methods currently used to forecast ...

Numerical models that combine weather forecasting and atmospheric chemistry are here referred to as chemical weather forecasting models. Eighteen operational chemical weather forecasting models on regional and continental scales in Europe are described and compared in this article. Topics discussed in this article include how weather forecasting and atmospheric chemistry models are integrated into...

The Goddard Earth Observing System composition forecast (GEOS-CF) system is a high-resolution (0.25°) global constituent prediction system from NASA's Global Modeling and Assimilation Office (GMAO). GEOS-CF offers a new tool for atmospheric chemistry research, with the goal to supplement NASA's broad range of space-based and in-situ observations. GEOS-CF expands on the GEOS weather and aerosol mod...

The Copernicus Atmosphere Monitoring Service (CAMS) delivers a wide range of free and open products in relation to atmospheric composition at global and regional scales. The CAMS Regional Service produces daily forecasts, analyses, and reanalyses of air quality in Europe. This service relies on a distributed modelling pro duction by 11 teams in 10 European countries: CHIMERE (France), DEHM (Denmar...

The objective of this paper was to review the integration of health impact assessment (HIA) into environmental health assessment (EIA) or EHIA, existing legal requirements for health risk analyses, and lessons learned for integrating HIA within EIA processes. The authors undertook literature searches for EHIA practices through academic publications, reports, and websites of public organizations an...

The attached slides are a tutorial on Health Impact Assessment (HIA) methods applied in different contexts. This method can be applied in the global scale (e.g. for the Global Burden of Disease), national scale (e.g. by the EPA to estimate PM2.5 burden of disease in the U.S.A), and at the local scale....

Health impact assessment is a systematic process that uses an array of data sources and analytic methods and considers stakeholder input to determine the potential effects of a proposed policy, plan, program, or project on the health of a population and the distribution of those effects within the population. HIA provides recommendations on monitoring and managing those effects. The goal of HIA is...

Health risk assessment is about providing information to make informed decisions. This document and framework have been developed to provide those involved in approval processes with an approach to consider health risks within the scoping stages of health and environmental impact assessments. The specific focus of the process described here is the Scoping stage of the approvals process but it coul...

The Guidelines for Preparing Economic Analyses are part of the U.S. Environmental Protection Agency's (the EPA's) commitment to improve the preparation and use of sound science in economic analysis to inform decision making. Written primarily for the economic analyst, the main purpose of this document is to define and describe best practices for economic analysis grounded in the economics literatu...
