Poverty Levels Data Access and Tools
Access a range of datasets and data tools to further your research into poverty levels including the POPGRID Viewer and SEDAC Population Estimator.
Featured Poverty Levels Observation Method: VIIRS
The Visible Infrared Imaging Radiometer Suite (VIIRS) is aboard the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) and NOAA-platforms. VIIRS collects visible and infrared imagery along with global observations of Earth's land, atmosphere, cryosphere, and ocean. The instrument can detect light from human settlements to measure the size and growth of those areas as well as changes to the regions as a result of power loss from storms, conflicts, and other events.
The Visible Infrared Imaging Radiometer Suite (VIIRS) will help ensure continuity of Earth observations after the upcoming retirement of the Moderate Resolution Imaging Spectroradiometer (MODIS).

Two new near real-time VIIRS products are available for download in NASA’s Land, Atmosphere Near real-time Capability for EOS (LANCE) and for interactive exploration using NASA Worldview.
