Biography
Alex Geddes is a remote sensing scientist whose career has spanned atmospheric aerosols, trace gases, and cloud and radiation processes. His PhD focused on the remote sensing of aerosols, followed by a postdoctoral appointment at the University of Toronto, where he developed and deployed balloon-borne FTIR instruments. Since joining NIWA/ESNZ, Alex has worked on advancing all-sky camera systems for cloud monitoring, developing UV spectral processing algorithms, and leading the redevelopment of UV spectrometers for long-term monitoring. His research later expanded to include ground-based inverse modelling of methane emissions in New Zealand, where he has become deeply involved in international methane science.
Alex is also plays a lead role in the agricultural component of the MethaneSAT and MethaneAIR, while also playing a central role in the newly funded FarmAI project, which leverages AI and Earth observation for farm-scale agricultural greenhouse gas monitoring. Recently appointed Remote Sensing Sector Lead, he is working to develop and support remote sensing capability across ESNZ, bridging scientific innovation with national-scale applications.
