About
Dr. Alan J. Collison is a leading expert in satellite remote sensing, with a primary focus on atmospheric correction for optical Earth observation. His work is critical for ensuring the accuracy of quantitative analyses derived from satellite imagery, particularly for land surface monitoring. Dr. Collison’s major contribution lies in the rigorous, large-scale validation of atmospheric correction algorithms. He is the lead author of the landmark "Atmospheric Correction Inter-comparison eXercise, ACIX-II Land" (2022), a highly influential study (63 citations) that systematically benchmarked the performance of state-of-the-art processors for Landsat 8 and Sentinel-2 data. This work established a vital, open-access framework for the community to assess and improve correction methods, directly enhancing the reliability of multi-temporal and multi-sensor remote sensing applications. Through this benchmark, Dr. Collison has provided an essential service to the global remote sensing community, enabling more accurate vegetation health monitoring, land cover change detection, and climate studies. His research is foundational for any scientist or student working with optical satellite data over land.
