I have meteorological daily sunshine duration, humidity, rainfall, and max-min temperature; 3 hourly cloud cover, visibility, wind speed with direction; global radiation data at 1 minute interval for a few years. I worked on predication of sunshine duration, solar radiation, etc. from other meteorological parameters. Now I have been studying the solar radiation forecasting methods for the last couple of weeks. There is a good number of options, like Clear sky models, regression methods, artificial intelligence, remote sensing, numerical weather prediction, local sensing, etc. in different journal papers. One of fellows are working on DNI measurement, finding the Linke Turbidity Coefficient and using clear sky models for solar radiation prediction for clear days. But I am not sure yet whether I can make forecast of solar radiation for any forecast horizon for Bangladesh. Would you mind to cooperate me in this regard?
