The GAINS PMEH-Methodology -Version 2.0

This document describes the methodology developed for the GAINS PMEH project. This methodology provides a framework for translating detailed data on emission control technologies and measures, atmospheric transport, costs, socio-economic development and health indicators from the GAINS databases into such a format and level of aggregation that they can be displayed and turned into an interactive decision support tool at various spatial scales, in particular the megacity scale. As an example we discuss the prototype for Hanoi and its environs.
