About
Wei-Chun Hung is a remote sensing scientist whose work centers on atmospheric correction and radiometric calibration for satellite imagery. His most-cited paper, "A path radiance estimation algorithm using reflectance measurements in radiometric control areas" (2011), introduces a novel method for estimating path radiance—a critical step in removing atmospheric interference from satellite images. By leveraging surface reflectance measurements from radiometric control areas (RCAs), Hung’s algorithm offers a practical alternative to traditional approaches like the dark object subtraction (DOS) method. Comparative analysis showed that the RCA-based technique yields more accurate path radiance estimates, directly improving the quality of land surface reflectance retrievals. This contribution is foundational for applications in environmental monitoring, agriculture, and land cover classification, where precise atmospheric correction is essential. With 5 citations, this work has informed subsequent studies in radiometric calibration and remote sensing data processing. Hung’s research addresses a persistent challenge in optical remote sensing, demonstrating a clear focus on enhancing data reliability for downstream scientific and operational use.
