Sensing Nitrogen Dioxide Exposure

Measurements from three satellite instruments monitoring tropospheric Nitrogen Dioxide (NO2) are combined and then run in a NASA chemical transport model to estimate ground-level concentrations of NO2 relevant to human exposure. Purple areas indicate high NO2 concentrations.

Health Risks of NO2

This map shows an estimate of ground-level NO2 levels for 2010 through 2012. High concentrations of NO2 (purple areas) are strongly related to premature deaths.


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.


The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.

EOSDIS SIPS and their Role Ensuring Consistent Long-Term Global Observations of Atmospheric Ozone

The OMI and OMPS Science Investigator-led Processing Systems (SIPS) ensure that ozone data collected by instruments aboard the Aura and Suomi-NPP satellites reach global users.

Getting Ready for NISAR—and for Managing Big Data using the Commercial Cloud

The upcoming NISAR satellite mission is expected to add as much as 85 TB of data each day to the EOSDIS archive. The commercial cloud is being explored as a way to archive and disseminate this extremely high volume of data efficiently.
