I posted on a set of climate observing station in the Netherlands in my post
Thanks to Marcel Severijnen we now have metadata photographic information on other sites within the Netherlands.
As Marcel told me, the operational stations in the Netherlands have extensive data and pictures available, even for the very old stations.
If others have such photographs for surface climate locations elsewhere around the world (excluding the USA which Anthony Watts and volunteers have so capably documented) please e-mail the url for them to me. An earlier post of urls with photographs of surface temperature sites was posted in
