I'm a structural engineer involved in the research and development of design and code procedures aimed at the rational use of Earthen materials in superstructures. This type of construction is clearly and continually exposed to the atmosphere. The materials function both structural and thermally by their diurnal as well as seasonal hygroscopic, mass, and radiative heat mechanisms. This active interaction with the ambient atmosphere implies the potential relevance to your study. I would like to keep abreast of your work and conclusions. Thank you for your work.
