Abstract
In this study, a set of four commercially available naturally ventilated radiation shields and a reference mechanically ventilated weather station were tested during three months of a hot Mediterranean summer in southern Europe. The results indicate that among the selected radiation shields, the naturally ventilated shield identified as shelter 2 with its inner temperature sensor has the best overall performance and could be used as a reference radiation shield, as its statistical errors were of the same order of magnitude compared with the reference mechanically ventilated weather station.
