About
Lawrence Ong is a leading figure in satellite radiometry and lunar calibration, whose work has been instrumental in advancing the precision of Earth-observing sensors. His primary research focuses on developing and validating methods for on-orbit radiometric calibration, with a particular emphasis on using the Moon as a stable, exoatmospheric calibration target. Ong’s most notable contribution is his foundational work on the Robotic Lunar Observatory (ROLO) project, where he co-developed a spectral irradiance model of the Moon that accounts for complex variations in lunar phase, libration, and spacecraft position. This model, detailed in his highly cited 2003 paper (33 citations), provides a critical methodology for comparing observations across different spacecraft and over time, enabling consistent, long-term climate data records. By solving the challenge of cross-calibrating multiple satellite sensors, Ong’s research has directly improved the accuracy of global climate monitoring, land surface studies, and atmospheric science. His work remains a cornerstone for agencies like NASA and NOAA, ensuring that decades of satellite data remain intercomparable and scientifically robust.
