Summary
This study used satellite data and Google Earth Engine to analyze thermal conditions in historic Cyprus clusters from 2013-2020. It identified seasonal land surface temperature changes and land cover anomalies using vegetation and building indices.
Area of Science:
- Environmental Science
- Remote Sensing
- Urban Climatology
Background:
- Historic urban clusters face unique thermal challenges due to building materials and microclimates.
- Understanding thermal conditions is crucial for heritage preservation and urban planning.
Purpose of the Study:
- To investigate macro-scale thermal conditions and land cover changes in historic Cypriot urban clusters.
- To analyze multi-temporal and seasonal variations in land surface temperature (LST).
- To identify potential land cover anomalies using remote sensing indices.
Main Methods:
- Processing over 140 Landsat 7 ETM+ and 8 LDCM images on Google Earth Engine (2013-2020).
- Multi-temporal thermal analysis to generate Land Surface Temperature (LST) products at 100 m resolution.
- Extraction of Normalized Difference Vegetation Index (NDVI) and Normalized Difference Build Index (NDBI) to detect land cover changes.
Main Results:
- Macro-scale identification of multi-temporal and diachronic changes in thermal patterns.
- Establishment of seasonal and location-based change patterns within historic building clusters.
- Correlation of thermal anomalies with land cover variations detected by NDVI and NDBI.
Conclusions:
- Satellite observations on cloud platforms provide effective macro-scale analysis of historic urban thermal environments.
- Seasonal variations significantly influence land surface temperature in historic Cypriot clusters.
- The methodology can identify critical areas for heritage management and urban adaptation strategies.

01:14Temperature Measurement Sites
2.5K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

01:43Thermosensation
32.7K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

02:46Quantifying Heat
59.2K
Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a...

01:21Masonry in Cold and Hot Weather Conditions
164
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.

01:50Global Climate Change
26.6K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

02:44Heating and Cooling Curves
24.9K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...
