I am doing an experiment with UV irradiation. I need to simulate natural sun radiated UV that naturally occurs in nature. how can I get the UV radiation Dose of a specific place at a specific time in the day in j/m2 unit? or how can I convert the UV index into UV dose?
Thank You!
Hi
You can find this thanks to this publication:
Article Solar Spectral Irradiance and Summary Outputs Using Excel
For the UV index just divide the UV index by 40 and you will have the uv dose

The UV index is a kind of integration by step of 0.025 W/m2 of the the so-called UV erythemal or UV-CIE. An index of 10 corresponds to 0.25 W/m2. UV index is used for daily mean of UV irradiance. If you need a daily irradiation in J/m2, multiply the UV index by 0.025 (get W/m2), then by the number of seconds in a day (24 h x 2600 s).
Hope it helps.
Best regards

Thank You so much Dear Dr. Marc Pissavini and Dr. Lucien Wald for your kind suggestion. I believe, this discussion will help me figure out my problem.
I also would like to ask your kind suggestion for a paper which i can cite while I am going to use this conversion method for my research thesis paper.
Highly Appreciate your time.
Thanks and regards,

FYI
have a look on this paper, you will find the UV index calculation but also a lot of very interesting information. A must have from B Diffey

If you consider the UV dose that is efficient for specific photobiological processes, you must remember that the constituents of the skin are important to account for as shown in this paper: https://www.sciencedirect.com/science/article/pii/S1011134405002071?via%3Dihub
