About
Steve E. Grantham is a leading figure in the field of radiometric calibration, with a primary focus on advancing the use of the Moon as a stable, SI-traceable calibration target for Earth-observing satellite sensors. His major contributions center on the development and deployment of the Airborne LUnar Spectral Irradiance (air LUSI) instrument, which enables direct, high-accuracy measurements of absolute lunar irradiance from an aircraft platform. This work is critical because the Moon’s radiometrically stable surface and Earth-comparable radiant flux make it an ideal reference, but its use requires precise, SI-traceable measurements to correct for varying illumination and viewing geometries. Grantham’s research directly supports the United States Geological Survey’s efforts to create robust lunar irradiance models, improving the long-term consistency of satellite data for climate and environmental monitoring. While his most-cited paper (2021, 2 citations) is foundational, his broader impact lies in establishing a calibration methodology that underpins global Earth observation. His work is essential for ensuring that decades of satellite data remain comparable, a key achievement for climate science.
