We are planning to do an evaluation of these water surfaces on thermal comfort. Of course we will measure air temperature, relative humidity, and wind speed. For mean radiant temperature we can use globe temperature. However, using this methodology to extract Tmrt, does anybody know to what extent the little drops of spray water influence the globe temperature and thus in correct derivation of Tmrt?
Additionally, has anybody evaluated their effect in urban areas? Do you know any literature references?
Dear Juan,
We have evaluated the role of water on the thermal comfort in these 2 papers, but did not look at the droplets specifically.

I hope this could be helpful:
