National Science Foundation

National Science Foundation is an independent U.S. federal agency that funds fundamental research and education across non-medical science and engineering and supports major research infrastructure.^[1] Its EO relevance is funding and supporting research infrastructure rather than flying satellites or using satellite data for operational decisions.^[1][2] NSF fully funds the National Ecological Observatory Network, a continental-scale ecological observatory operated by Battelle with 81 field sites across U.S. ecosystems.^[2] NEON's Airborne Observation Platform conducts airborne remote-sensing campaigns with discrete and full-waveform LiDAR, an imaging spectrometer, and a high-resolution digital camera over flight boxes at peak greenness.^[2] The program publishes open data products across Level 1, Level 2, and Level 3 processing, making NSF relevant to EO buyers looking for airborne ecological reference data and infrastructure rather than satellite procurement.^[2]
