Niall Origo

Senior scientist


Niall Origo is a Senior Research Scientist in Earth Observation. His work focuses on the application of metrology, radiative transfer modelling and field instrumentation to the measurement of vegetation related biophysical variables.

Niall joined NPL in 2012 after completing the MSc Remote Sensing at University College London (UCL). He is currently finishing a PhD in Remote Sensing at UCL looking at the measurement and modelling of the fraction of absorbed photosynthetically active radiation (fAPAR).

Understanding the role of and changes in vegetation is critical for climate change, food security and disaster management applications. Niall’s work develops novel methods to understand the quality of the data feeding into these applications. Examples of work he leads includes the development and utilisation of virtual replicas of real vegetated field sites, establishment and maintenance of sensor networks for satellite validation, and the application of hyperspectral imaging from UAVs to retrieve satellite validation data.
