Sensing Our Planet: NASA Earth Science Research Features 2008 features an article on how SEDAC data was used for the 2008 Environmental Performance Index and other environmental assessments; CIESIN’s Marc Levy is interviewed.

Spatial disparities within Urban Settlements

Map of Spatial disparities within Urban Settlements

A typically higher standard of living in urban areas compared to rural ones does not rule out striking disparities within cities. SEDAC data from its Global Poverty Mapping Project is used as the basis for this  map. Map 1.2, illustration for Chapter 1--Density, The World Development Report Online 2009.

Another Way to Look at an Air Quality Problem

Satellite image of a particularly valuable perspective on PM2

Satellite data offer a particularly valuable perspective on PM2—small particles deriving mostly from burning fossil fuels and biomass, which can harm human health—because ground instruments may be unavailable or offer limited information, as is the case in China. With that in mind, researchers at Columbia University’s Earth Institute and Batelle Memorial Institute have developed maps based on satellite data that depict annual PM2.5 exposure in all of China’s provinces.

A Catalog of Change

CIESIN’s role in making climate change data freely available to the public is noted in an article in this annual collection of articles about how scientists use Earth science data to learn about the planet.
