Earth Observatory is a NASA-sponsored online resource that provides satellite imagery, scientific visualization, and analysis of Earth systems using data from spaceborne sensors and collaborative research. It serves as a nexus connecting observational assets like Terra (satellite), Aqua (satellite), and Landsat with research programs such as Global Change Research Program, Earth Science Division (NASA), and initiatives coordinated with United States Geological Survey, National Oceanic and Atmospheric Administration, and international partners. The project supports interdisciplinary studies spanning climate change, hydrology, volcanology, atmospheric science, and biosphere dynamics to inform stakeholders including United Nations Environment Programme, Intergovernmental Panel on Climate Change, and World Meteorological Organization.
The platform synthesizes observations from platforms including Terra (satellite), Aqua (satellite), Aura (satellite), Suomi NPP, Landsat, Sentinel-2, GOES-R series, MODIS, VIIRS, ASTER, CALIPSO, ICESSat-1, and GRACE to produce analyses used by researchers at NASA Goddard Space Flight Center, Jet Propulsion Laboratory, Goddard Institute for Space Studies, and academic institutions such as Massachusetts Institute of Technology, California Institute of Technology, Columbia University, Stanford University, University of California, Berkeley, University of Colorado Boulder, and University of Maryland. It highlights phenomena associated with events like the 2010 Eyjafjallajökull eruption, 2015-2016 El Niño, Hurricane Katrina, 2011 Tōhoku earthquake and tsunami, and seasonal cycles in regions including the Amazon rainforest, Sahara Desert, Antarctica, and the Arctic. Linked collaborations include European Space Agency, Japan Aerospace Exploration Agency, Canadian Space Agency, Indian Space Research Organisation, and Brazilian Space Agency.
The initiative was launched in 1999 within NASA at facilities including Goddard Space Flight Center to make satellite data accessible to the public and scientific community, complementing long-standing programs such as Landsat program and missions from National Oceanic and Atmospheric Administration. Early coverage connected to events like the 1997–98 El Niño, scientific assessments by the Intergovernmental Panel on Climate Change, and observational syntheses from International Geosphere-Biosphere Programme. Over time the resource expanded coverage to integrate data from missions such as GRACE-FO, ICESat-2, Sentinel missions, and commercial partnerships with corporations like Planet Labs and Maxar Technologies. The editorial and visualization approach evolved alongside standards promoted by Group on Earth Observations and data frameworks developed by Committee on Earth Observation Satellites.
Data contributors include spaceborne sensors and missions: MODIS on Terra (satellite) and Aqua (satellite), VIIRS on Suomi NPP, Landsat 8, Landsat 9, ASTER on Terra (satellite), CALIPSO lidar, CloudSat, GRACE and GRACE-FO gravimetry, ICESat-2 altimetry, Sentinel-1, Sentinel-2, and Sentinel-3 series from European Space Agency. Atmospheric composition is informed by Aura (satellite) instruments like OMI and TES, while microwave remote sensing comes from SMAP and GPM, and weather products rely on GOES-R series and Meteosat datasets. Ancillary inputs come from United States Geological Survey field campaigns, International Satellite Cloud Climatology Project records, reanalysis products from European Centre for Medium-Range Weather Forecasts, National Centers for Environmental Prediction, and cryospheric observations by National Snow and Ice Data Center.
Analyses inform work in climatology and impact assessments for events such as Hurricane Maria, Cyclone Idai, and droughts affecting the Horn of Africa and California droughts. Research outputs support modeling efforts at Goddard Institute for Space Studies, NASA Jet Propulsion Laboratory, and university centers like Lamont–Doherty Earth Observatory, Scripps Institution of Oceanography, NOAA Geophysical Fluid Dynamics Laboratory, and Potsdam Institute for Climate Impact Research. Studies use datasets to monitor deforestation in the Amazon rainforest and Congo Basin, sea-level change observed by TOPEX/Poseidon successor missions, glacier mass balance studies referencing Himalayan glaciology and Patagonian ice fields, wildfire tracking in Australia, California, and boreal regions, and urban heat island analyses for cities including New York City, Los Angeles, Delhi, Beijing, and London. Cross-disciplinary projects integrate outputs with initiatives such as Group on Earth Observations and Global Earth Observation System of Systems.
Operational oversight is rooted at NASA centers including Goddard Space Flight Center with coordination among the Earth Science Division (NASA), editorial teams, visualization specialists, and data engineers collaborating with partners such as USGS, NOAA, ESA, JAXA, CSA, and academic consortia like Earth Science Information Partners. The platform relies on data policies consistent with principles from Committee on Earth Observation Satellites and data infrastructure from NASA Earthdata and Open Geospatial Consortium standards. Staffing comprises scientific editors, visualization programmers, and outreach coordinators who work with mission science teams from Terra (satellite), Aqua (satellite), Sentinel, and other mission offices.
Content is tailored for audiences ranging from researchers at University of Oxford and Princeton University to educators in museums such as the Smithsonian Institution and students in programs run by National Science Foundation grants. Educational resources align with curricula influenced by standards from Next Generation Science Standards and outreach collaborations with institutions like American Geophysical Union, European Geosciences Union, Royal Meteorological Society, and non-profits such as The Nature Conservancy and World Wildlife Fund. Public-facing products include time-series visualizations, annotated imagery for events like the 2018 Sulawesi earthquake and Mount Merapi eruptions, lesson plans, and multimedia features promoting literacy used by NASA Earth Science Education Collaborative and teacher networks.
