Now available: Detailed air quality estimates for public health research developed by Harvard researchers and released by NASA SEDAC; for urban and non-urban areas of the US 2000‒2019.

According to the World Health Organization (WHO), exposure to air pollution—primarily outdoor air pollution—accounts for seven million deaths each year globally, and around 91% of the world’s population lives in places where air quality levels exceed WHO limits. Air pollution affects both deve...

New Natural Hazards Index!

CIESIN helped with GIS analysis for a new mapping tool examining weather & climate vulnerabilities across the U.S, from The National Center for Disaster Preparedness (NCDP), the Columbia University Climate School. This major upgrade to the tool, first released in 2016, displays hazards data of 14 types, in the US and Puerto Rico (where available) at the census tract level.

Product Overview The first step in disaster preparedness, according to the NCDP Model of Preparedness, is to know your risks. Knowing which hazards exist

Air pollution is a serious problem around the globe, and although there are many toxins that can adversely affect human health, the pollutants thought to pose the biggest risk to public health include fine particulate matter (PM2.5), ozone (O3), and nitrogen dioxide (NO2).

To assist public health, environmental, and air quality researchers in their investigations of pollution’s effects on human health, NASA’s Socioeconomic Data and Applications Center (SEDAC) has released an Air Quality Data for Health-Related Applications data collection consisting of three datasets: Daily and Annual PM2.5 Concentrations for the Contiguous United States (2000–2016), Daily 8-Hour Maximum and Annual O3 Concentrations for the Contiguous United States (2000–2016), and Daily and Annual NO2 Concentrations for the Contiguous United States (2000–2016).

The datasets were developed by a team of researchers from Harvard University’s T.H. Chan School of Public Health (SPH) led by Dr. Joel Schwartz, Professor of Environmental Epidemiology.
“There has long been a recognition that satellite data could inform the measurement of air pollutants such as PM2.5, NO2, and O3,” said Dr. Alex de Sherbinin, SEDAC deputy manager. “PM2.5 in particular is one of the leading killers in the world. If you look at the global burden of disease, it’s among the top causes of premature death, particularly in regions like Asia where pollution levels are high owing to coal-fired power plants. Dr. Schwartz’s data are important for many users in the public health and environmental fields, and a complement to a number of global gridded products hosted by SEDAC that measure average PM2.5 and NO2 concentrations at annual time steps.”

Image: This map displays the annual average concentration in micrograms per cubic meter of PM2.5 predictions for 2016 gridded at a spatial resolution of 1 km. Areas of dark brown indicate higher concentrations and areas of light brown indicate lower concentrations.
