Dear all,
I am a student at Maseno University, Kenya.

I have daily data for temperature, rainfall and sunshine hours with some records missing.

I used Weatherman to fill the gaps and it did well for the temperature and rainfall. I had also set it to fill sunshine hours but instead, data for solar radiation was generated. 

I will appreciate it if anyone can help inform me the limitations that exist with generation of the sunshine hours. Also, how could I have set up weatherman to help me get the sunshine hours? 

I appreciate your responses.

Regards,

Thomas Mawora
