Photographs of the microclimate monitoring systems that were implemented in the study: (A) Air temperature and humidity sensor in a 12 cm diameter radiation shield. (B) Light sensor mounted ~10 cm above the rock surface in a stand. (C) Conductivity sensor (one of six). (D) Dew sensor (7 cm on a side) 4. Not shown are the rock temperature sensors and the tipping bucket rain gauge. (Photographs by Irit Nir). (E) Geological Map of Timna Park showing the location of the rain gauge in Timna Park. (F) Stratigraphy Index of the Geological map (Origin of the map and the index: Beyth et al. 1999). -- Environmental Geology Reports
