The knowledge of the global solar surface irradiance (SSI) incident on the earth's surface and its spatiotemporal distribution is important to numerous solar-based applications. However, spatiotemporal modelling of SSI (a non-linear process) from Earth observation data is unfortunately not straightforward. From a signal processing perspective, it is a non-stationary, non-linear/non-Gaussian dynamical inverse problem. In this paper, we propose an MCMC particle filter approach that combines satellite images and in situ data for space-time-referenced SSI modelling. We propose original observation and transition functions taking advantage of the characteristics of the involved types of data. A simulation study of solar irradiance is conducted in parallel with this method and a map of SSI potential in French Guiana for the year 2012 is provided.
