Land Surface Temperature (LST)
Global warming has been a concern since the late nineteenth century. Especially in cities and urban areas, the average land surface temperature (LST) increased more and resulted in urban heat islands (UHIs). Given this fact, we in GeoAI ask further that what in cities lead to the increased LST, and how the linkages between city planning / construction and UHI can be determined.
Land Surface Temperature (LST) measures the temperature of the Earth’s surface. It reflects heat absorbed and emitted by the land.
What Is Land Surface Temperature (LST)?
LST indicates the surface temperature of land areas. It changes due to sunlight, vegetation, materials, and atmospheric conditions.
LST differs from air temperature because land tends to heats and cools faster than air. It shows the surface’s immediate heat conditions, offering critical environmental and climatic insights.
How Do We Measure Land Surface Temperature?
Ground-Based Measurements
- Researchers use infrared thermometers to record surface temperatures in small, specific areas.
- Meteorological stations install sensors to track continuous temperature changes.
Remote Sensing
- Satellites like Landsat and Moderate Resolution Imaging Spectroradiometer (MODIS) capture surface temperatures using thermal infrared data.
- Drones equipped with thermal cameras collect high-resolution temperature data over specific regions.
How Can You Access LST Data?
Free Satellite Data
- Landsat provides thermal infrared data with medium resolution for environmental studies.
- MODIS offers daily global coverage suitable for large-scale monitoring.
- Sentinel-3 delivers precise thermal data for detailed temperature measurements.
Ground-Based Data
- Meteorological networks and local stations collect surface-level temperature data.
- Researchers use field campaigns to validate satellite measurements and models.
What Do We Use LST For?
- Urban Heat Island Studies: Identify urban areas with higher temperatures to address heat stress and improve city planning.
