Monthly DNI solar map UAE&Qatar 3km Masdar Institute July 2009

The UAE solar atlas utilizes satellite imagery through a robust ANN model to map the solar potential across the country. Estimated irradiance is subsequently validated against independent ground data.

Direct normal irradiance (DNI), diffuse horizontal irradiance (DHI) and global horizontal irradiance (GHI) are produced at a 3 km spatial resolution and in a near real-time manner (updated every 15 min). Hourly, daily, monthly and yearly irradiation maps for all three components are derived as the final product. The UAE Solar Atlas report with a detailed explanation of the methodology and results is available at atlas.masdar.ac.ae/docs/ReCREMA_UAE_Solar Atlas_Report.pdf Relevant publications: Eissa, Y., Chiesa, M., Ghedira, H., Assessment and recalibration of the Heliosat-2 method in global horizontal irradiance modeling over the desert environment of the UAE, Solar Energy, Vol. 86, pp 1816-1825, 2012.
