# Indoor Microclimate Analysis of the San Panfilo Church in Tornimparte, Italy
## 2 Materials and Methods
### Monitoring Campaign  
Monitoring activity started in February 2021 and ended in April 2022. The two main microclimatic parameters, temperature and relative humidity, were measured inside and outside the church. The monitoring activity was organized into two main phases: intensive measurements and continuous measurements.  
Intensive measurements were performed on specific days (18 February 2021, 6 July 2021, 22 November 2021, 22 April 2022) chosen along the year with the aim to inspect in detail the situation inside the church through the seasons. Temperature and relative humidity were measured two times a day (in the morning and early afternoon) at two vertical levels (1.2 m and 2.0 m from the floor) on a regular grid (Figure 2a).  
On 22 April 2022, some additional measures of temperature and relative humidity were performed at four levels from the floor (0.5, 1.2, 2.0, 3.0 m) in the apse. Moreover, on 22 November 2021 and 22 April 2022, the apse wall temperature was measured with an infrared thermometer.  
Continuous measurements were performed from 20 February 2021 to 18 April 2022 in several sites in the church and two sites outside the church (Figure 2b, Table 1) at a monitoring frequency of one datum every 10, 15 or 60 min. The apse was monitored using two sensors placed on the glass showcase (positions 1 and 2), two sensors tied to the crucifix (positions 3 and 4) and three sensors placed near the walls on two little shelves (positions 8 bis, 13, and 14). In the main wave the monitoring sites were at the balustrade (positions 5 and 6), on the pulpit (position 7), on the first column capital (position 8) and on the choir (positions 9 and 10). The outdoor environment was monitored using a sensor below the external portico (position 11) and near the meteorological station located at Colle San Vito (latitude: 42.290639\({}^{\circ}\) N, longitude: 13.289556\({}^{\circ}\) E) at a distance of about 1 km from San Panfilo church. This station is managed by the Centro Funzionale and Ufficio Idrografico of Regione Abruzzo.

Some microclimatic parameters such as specific humidity, dew point temperature and dew point spread were computed from temperature and relative humidity data.
