Dr. Jose A. Ruiz-Arias

Job Title
Weather and Solar Radiation Modelling Expert
Solargis s.r.o

ose Antonio Ruiz Arias is Weather and Solar Radiation Modelling Expert in Solargis. He received the Electronic engineering degree (2004) and the B.Sc. degree in Physics (2006) from the University of Granada (Spain). In 2008 he received the M.Sc. degree in Geophysics and Meteorology from the University of Granada (Spain) and, one year later, he got the Ph.D. in Physics from the University of Jaén, Spain. Since then, he has researched short-wave solar radiation and its applications in the field of renewable energies. He has authored and co-authored more than 50 publications in high-impact scientific journals and has participated in nearly 100 contributions to international scientific conferences. Dr. Ruiz-Arias is an expert user and code contributor of the Weather Research and Forecasting (WRF) numerical weather prediction model. He is also expert in Geostatistics, short-wave solar radiation modelling at high temporal and spatial resolution, including terrain effects using Geographical Information Systems and the modelling of atmospheric aerosol for short-wave solar radiation assessment. He accumulates experience in large-scale PV and CSP potential evaluation, wind modelling, and artificial intelligence techniques for data analysis.

From 2011 to 2014, Dr. Ruiz-Arias led the SolForRenew European project in coordination with Dr. Jimy Dudhia′s team at the Mesoscale and Microscale Meteorology Division of the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, and participated actively in the development of the WRF-Solar suite of the WRF model aimed at the forecasting of solar radiation from few hours to various days ahead. Dr. Ruiz-Arias introduced numerous improvements in WRF-Solar for the modelling of clear-sky fluxes, including a new parameterization for aerosol optical properties. Since early 2016, and after two years working as research associate in the University of Málaga (Spain), Dr. Ruiz-Arias joined Solargis, where he is science developer and supporter of the Solargis solar radiation forecasting service.

Dr. Ruiz-Arias is part of the Task 46 expert committee of the Solar Heating and Cooling Programme of the International Energy Agency (IEA) ( on Solar Resource Assessment and Forecasting. He is leader of sub-task D.1 on Advanced Resource Modelling and improvement of existing solar radiation retrieval methods and Activity 1.2 of the forthcoming IEA-Photovoltaic Power Systems (PVPS) Programme Task 16 on “Solar resource for high penetration and large scale applications”.
