Microclimate for Cultural Heritage

...highly recommended book. Il Nuovo Cimento Vol. 22, no. 1 A. Longhetto Even the most casual reader of the conservation literature will have encountered examples of the remarkable body of work by Dario Camuffo wherein he has applied fundamental principles of physics to the study of the microenvironment of such diverse systems as temperature and humidity gradients in the Sistine Chapel, acid deposition and biocorrosion on Trajan's column, and the aeolian erosion of the Great Sphinx. The present work is no mere compilation or recapitulation of the author's previously published papers, but rather a publication of the fundamental principles and theoretical basis for the study of the microenvironments encountered by the most diverse forms of cultural property. It is appropriate that it finds its place in the series, 'Developments in Atmospheric Science' among such titles as Physical Principles of Micro-Meteorological Measurements, Man's Impact on Climate and Atmospheric Aerosols. Where rigor is called for, the treatment includes derivations and equations. Yet the author never allows rigor mortis to set in. Always, clear practical examples are provided. Indeed, the theoretical treatment is at the service of the discussions of the many case studies introduced. It is perhaps useful to consider Camuffo's text in parallel to the widely read classic by Garry Thomson, The Museum Environment. In attempting to deal with the different levels of scientific appreciation brought by his prospective readers, Thomson covers the same material twice, offering, in effect, an introductory version and then a more advanced version for each topic. This solution always seemed rather artificial. It is much to the credit of Dr. Camuffo that he has written a book that may be the advanced-level version of The Museum Environment, while integrating the treatment in such a way that the conservator, the conservation scientist and the atmospheric physicist can all turn to it for reference and even enjoyment. The book is divided into two parts, 'Atmospheric physics applied to microclimate analysis and conservation' and 'Performing microclimate field surveys'. The first part, which forms approximately three-quarters of the text, covers microclimate, air and temperature; humidity, the description of air masses and vertical motions; radiation and light; the physics of drop formation and micropore condensation: atmospheric water and stone weathering; atmospheric stability and pollutant dispersion; and dry deposition of airborne particulate matter. The second part deals with practical aspects of field measurement and survey for parameters associated with temperature, humidity, wind, indoor air motion, rainfall and windborne droplets. A great number of diagrams and photographs with clear explanatory captions support the exposition. The generous inclusion of a few color plates is a pleasant extravagance. In sum, Dario Camuffo has provided a definitive treatment of a central aspect of conservation science and a most useful introduction to the application of atmospheric physics to the preservation of cultural property. The practising conservator, especially one who looks askance at the differential equations that not infrequently grace the pages of this journal, would also benefit from an acquaintance with this book. In that regard, it is a pity that the otherwise most thorough subject index does not include the names of the many monuments that form the case studies and practical examples discussed.
