“…Nevertheless, a diurnal temperature variance of around 12°C is probably negligible for thermal stress if compared with other studies on stone heritage (Al-Omari et al 2014). Even if surface temperatures are considered equivalent to air temperatures with an approximate increase in 20°C (Bonazza et al 2009), isolation weathering has only been found relevant for thermal cycles over 40-50°C (Lazzarini and Tabasso 1986;Viles 2005;Brimblecombe 2014) and this threshold is far from the mean temperature variations found at any of the positions in Complutum.…”

Excavated archaeological sites are frequently exposed to damaging environmental conditions, which could lead to rapid decay especially for vulnerable heritage such as mosaics. One of the most common solutions is the construction of shelters; however, some may not behave as expected, either because they do not protect adequately or induce decay. An environmental monitoring programme was undertaken inside and outside the two types of shelters at the Roman archaeological site of Complutum (Alcala de Henares, Spain) from May to September in 2018 and 2019. Hourly temperature and relative humidity readings collected by data loggers, together with rainfall data from a local meteorological station, have been comparatively assessed to better understand the consequences of sheltering in dry and warm areas. The results indicate that both shelters are avoiding further decay by keeping a more stable environment in relation to outside, although the more enclosed structure would be the most suitable one.

“…The reviews written by Hanef et al (1992), Steiger (2003), Sabbioni (2003), Grzywacz (2006) and Brimblecombe (2011) all agree on the fact that the acidic components generated by the transformations of the gaseous species are responsible for the preferential dissolution of minerals or/and for the growing of neoformed products (saline neocrystallizations) which coalesce and favour the formation of crusts. The nature of these crusts (carbonate, sulphate, nitrate, acetate, formate) depends on the one of the precursor gas (CO 2 , SO 2 , NO 2 , VOC).…”

An approach consisting in combining in situ and laboratory experiments is often favoured for investigating the mechanisms involved in the weathering of the materials of the cultural heritage. However, the realistic simulation in the laboratory of the environmental conditions ruling the interactions of atmospheric compounds with materials is a very complex task. The aim of this work is to characterise CIME, a new chamber specially built to simulate the interactions between materials of the cultural heritage and the environment. The originality of this instrument is that beside the usual climatic parameters (temperature, relative humidity, solar radiation) and gaseous pollutants, it also allows the controlled injection of different types of particulate matter such as terrigenous, marine and anthropogenic. Therefore, varied realistic atmospheric environments (marine or urban) can be easily simulated within CIME. In addition to the technical description of CIME, this paper shows the first results obtained by the impact of gaseous pollutants on non-durable glass, bronze and limestone. The first experiments for the deposition of different particles (calcite, clays, soot and halite) are also presented.

“…However, it is probable that the increase of rain and humidity will lead to an increase of the cumulative microorganisms concentration. This biological proliferation will add to other harmful effects, such as salt crystallization [27].…”

Buildings and monuments are often colonized by microorganisms that can result in colour change and aesthetical and physico-chemical damages. This bio-colonization is dependent of the material and on the environment. In order to better understand and correlate the microbial development at the surface of buildings with meteorological parameters, concentration of green algae and cyanobacteria have been measured using an in situ instrument on the wall of a private habitation in the Parisian region during two periods: spring and fall-winter. Different locations were also chosen to assess the influence of the position (horizontal or vertical) and of the situation (shaded vs. sunny microclimate). The results show that the microorganism development rapidly responds to rainfall events but the response is more intense in winter as temperature is lower and relative humidity (RH) higher. Cyanobacteria are less sensitive to this seasonal effect as they are more resistant to desiccation than green algae. Based on all the data, different dose-response functions have been established to correlate RH, rain and temperature to the green algae concentration. The influence of the microclimate is considered via specific fitting parameters. This approach has to be extended to new campaign measurements but could be very useful to anticipate the effect of climate change.
