About

Giulietta S. Fargion is a leading figure in satellite ocean color science, whose career has been defined by advancing the calibration and validation (Cal/Val) of remote sensing instruments. Her research focuses on ensuring the accuracy and consistency of ocean color data from multiple satellite platforms, a critical need for studying marine ecosystems and coastal processes. Dr. Fargion made foundational contributions through her work with the NASA SIMBIOS Project, where she led efforts to intercompare and cross-calibrate a suite of global ocean color sensors, establishing protocols that remain influential. She later pioneered a novel methodology to identify optimal in-situ sampling locations for calibrating hyperspectral and multispectral data in optically complex coastal waters. Her applied expertise is further demonstrated by her development of regional vicarious gain adjustments for the VIIRS instrument, directly improving the quality of operational ocean color products for the Joint Polar Satellite System. With her work cited across the field, Dr. Fargion’s legacy lies in building the rigorous Cal/Val framework that underpins reliable satellite observations of our changing oceans.
