Impact: Health Exposure, Visibility, Radiation

Purpose: Estimate the current and forecast health impact of air pollution and the human population

Background:The health impact of air pollution arises from exposure to high pollution concentrations at the surface where people reside. The exposure can be calculated from the surface concentration and from the population density

Impact Assessment Tool: The analysis tool consists of display/browser of observed AQ data, population density data and calculated population exposure data.

Usuage: A air quality manager is monitoring current and forecast exposure pattern through an appropriate ‘health impact dashboard’. When the forecast exposure exceeds a threshold, the manager issues an ‘air pollution advisory’ or warning.

Services: Each data set is accessed through WMS/WCS/WFS, Portray, Overlaid, augmented by data wrappers and adopters. Chaining is executed at multiple servers to demonstrate interoperability. The tool is a special client.

Service Integration: A special client that allows data overlay, browsing as well as zoom and pan, in space and time. The resulting exposure pattern are exposed as WCS and WMS maps for further use by other clients.

Problems: ??
