About
Christian Buil is a leading expert in radiometric calibration and optical sensor metrology for Earth observation satellites. His research focuses on ensuring the absolute accuracy and consistency of space-based measurements, particularly through the use of stars as stable, on-orbit radiometric references. Buil’s major contribution is the development and validation of methodologies that allow high-resolution optical sensors, such as those on the PLEIADES-HR satellites, to be calibrated against stellar sources—a technique critical for cross-sensor harmonization and long-term climate data records. His most-cited work, "The stars: an absolute radiometric reference for the on-orbit calibration of PLEIADES-HR satellites" (2017, 7 citations), exemplifies this breakthrough, demonstrating how stellar photometry can achieve the stringent accuracy demanded by international working groups like CEOS/WGCV and GSICS. Beyond this, Buil actively contributes to the global effort to standardize calibration practices, ensuring that measurements from different space agencies are interoperable and reliable. His work is foundational for researchers and engineers seeking to improve the fidelity of Earth observation data, from vegetation monitoring to climate modeling.
