### Wind-Driven Rain (WDR) and Other Weather Data  
#### 3.3.1 Wind-Driven Rain (WDR) and Dominant Winds  
The annual amount of wind-driven rain (WDR) varies significantly based on wall orientation, as shown in Table 2 and Figure 8. The North-West side is the most affected by WDR, with a value of 315.60 kg/m\({}^{2}\cdot\)a. On the contrary, the South-East side is the least affected, with a value of 157.99 kg/m\({}^{2}\cdot\)a. This trend is consistent over a 20-year period, with the North-West side always being the most affected by WDR (Figure 8c). Figure 7: Wide penetration of the fungal hyphae of _Acarospora impressula_ (RIL 5a) enhanced through false color SEM-images. Images also show that mineral grains are completely embedded in the hyphae networks, and the rock’s structure is superposed by the fungal network. \begin{table}

Table 2: Wind-Driven Rain (WDR) values in the main exposition of the church, as resulting from the data of weather station in Kayseri and Güslehir area. Figure 8: Wind-driven rain (WDR) loads (**a**) in the annual period 2019–2020 kg/(m\({}^{2}\cdot\)a)]; (**b**) among the four periods kg/(m\({}^{2}\cdot\)h)]; (**c**) in long-period from 2000 to 2020 kg/(m\({}^{2}\cdot\)a)]; (**d**) number of hours with WDR events in 2019–2020 period (measured by weather stations in Kayseri and Güslehir). Monthly data for 2019-2020 (see Figure 9) indicate that in March, the North-East side receives the maximum amount of WDR compared with other months and sides. To underline the trend in correspondence to the seasonal differences, the year has been divided into Winter (December, January, February), Spring (March, April, May), Summer (June, July, August), and Autumn (September, October, November). Figure 8b (blue line) shows that during Winter, the West and North-West sides are the most affected by WDR, while during the Spring (yellow line), the North-East side is most affected due to the abundance of WDR values in the March month. Figures 9 and 10 illustrate the number of hours with WDR events and the hourly amounts of WDR on different walls. The West and North-West sides are the most exposed with about 150 h of WDR events. Additionally, Figure 10 shows two extreme WDR events on the North-East side, with approximately 35 kg/m\({}^{2}\) and 28 kg/m\({}^{2}\), constituting about 40% of the total WDR amount, while the West and North-West sides have the highest number of WDR hours and the highest number of extreme WDR (\(>\)20 kg/m\({}^{2}\)).
