About
My interest is the use of global satellite remote sensing to improve understanding of climate change, vegetation health and carbon uptake, and the role of land/atmosphere interactions. I have developed a widely used model (FLIGHT), based on Monte Carlo solution of radiative transfer (North, 1996). This is used to model vegetation photosynthesis and light use efficiency, to relate satellite-measured spectra to land surface properties, and has been extended to model light detection and ranging (LiDAR) (North et al., 2010, Morton et al., 2014), and solar induced fluorescence (Hernandez-Clemente et al 2017). The role of atmospheric aerosols such as wildfire emissions and desert dust is currently a key uncertainty in climate change, air quality, and measurement of the Earth's reflectance. I have developed a method for estimation of atmospheric aerosol loading and surface reflectance (North, 2002, Bevan et al., 2012, Vogel et al 2022). This has been operationalised to provide a long-term global record using the European Space Agency instruments ATSR-2 and AATSR (1995-2012), and continuously updated for the Copernicus Sentinel-3 missions (2016-current). The research is funded under the ESA Climate Change Initiative, and UK NERC Earth Observation Climate Information Service (EOCIS) to provide information for international climate forecast agencies.
