Researchers from Pennsylvania State University and the University of Southampton in the UK have released five years of satellite data to help researchers better measure human population dynamics. The data originates from the U.S. Department of Defense’s Defense Meteorological Satellite Program, and it includes data measuring the daily brightness of five cities in Niger and Nigeria from 2000 to 2005 at night. Researchers can use this data to analyze how population fluctuations correlate with different outbreaks of infections, such as measles.
