Kevin Ahlgren

Kevin Ahlgren works on geodesy, the science of precisely measuring the Earth's shape and gravity field, with a focus on building accurate geoid models (mathematical surfaces representing sea-level-equivalent height used as a reference for elevation measurements). Much of the work centers on Colorado and Alaska, using airborne and ground-based gravity data, GPS/GNSS measurements, and modern surveying instruments to improve height reference systems used in mapping and surveying. This research supports national and international efforts to define more accurate height standards, including U.S. and international height reference systems.

Publication output was fairly active from 2017-2021 (2-5 papers per year) but has slowed noticeably since 2022, with only a few publications and some years with none.
