02 Beyond NASA
Partner agencies & open data
The atlas reaches outside NASA for free data that helps answer real questions — from ESA's Sentinels to population layers that show who is affected.
ESA — Copernicus
Sentinel-1/2/3/5P: radar, 10 m optical, ocean colour, air quality.
NOAA
GOES storms, HRRR/GFS weather, streamflow & air-quality ground truth.
USGS
Landsat (built with NASA): the 50-year surface-reflectance archive, plus real-time streamflow gauges.
USDA
NAIP: leaf-on, sub-metre aerial imagery of the continental US — farms, fields and land use up close.
Open-data orgs
Free layers that answer 'who/where is affected'.
