Machine learning models to predict diffuse solar radiation based on diffuse fraction and diffusion coefficient models for humid-subtropical climatic zone of India

Cleaner Engineering and Technology, 2021
In the present work, twelve machine learning (ML) models are developed for assessment of monthly average diffuse solar radiation (DSR) with solitary input forecaster as clearness index. Two categories of ML models were demarcated (i.e.

Prediction Of Clearness Index For Some Nigerian Stations Using Temperature Data [PDF]

, 2008
Global solar radiation and mean temperature data for five Nigeria stations have been used to fit the Angstrom model for the clearness index (KT =H/Ho), the mean temperature (Tmean) and maximum temperature (Tmax). The tests of performance of the model for
