@Article{, title={ANALYSIS OF SOLAR RADIATION Data IN CIRCULAR MODEL BASED ON NATURAL NEIGHBOUR INVERSE DISTANCE WEIGHTED}, author={Nasir Ahmed Al_awad and Ghusoon Idan Arb}, journal={Journal of Engineering and Sustainable Development (JEASD) مجلة الهندسة والتنمية المستدامة}, volume={22}, number={2 conference proceedings (Part-5)}, pages={86-93}, year={2018}, abstract={The central qualities of sun powered radiation in Iraq are condensed, and the choice of those destinations with potential for advancement of sunlight based plants depends on the nearby most extreme sun oriented radiation. The mapping of worldwide sun powered radiation is critical in outlining of sun based vitality framework and sustainable power source applications, additionally the worldwide sun based radiation estimation and mapping will encourage designers and planner purposes and applications. In this paper estimated and evaluated worldwide sunlight based radiation information was utilized. The estimation of worldwide radiation information can give comes about with satisfactory precision to build up sun powered maps of month to month radiation utilizing Natural Neighbour Inverse Distance Weighted (NNIDW) Method with circular model.
