Introduction to Thermal Infrared Remote Sensing Technology

Thermal infrared remote sensing is a remote sensing technology that uses infrared energy radiated by objects on the earth's surface to obtain information. It uses the thermal radiation characteristics of objects to obtain surface temperature, thermal radiation flux, and other heat-related parameters. By detecting thermal radiation energy on the surface, thermal infrared remote sensing technology can reveal the thermodynamic processes and energy exchange on the land surface.

Application of thermal infrared remote sensing in land surface energy balance

Land surface energy balance refers to the balance between the solar radiation energy received by the surface and the energy released by the surface to the atmosphere and underground. Thermal infrared remote sensing can study and monitor the distribution and changes of land surface energy by measuring surface temperature and radiation flux. By analyzing thermal infrared remote sensing data, surface evapotranspiration, surface heat flux, and other parameters related to energy balance can be inferred, thereby helping researchers better understand the thermodynamic processes on the land surface.

Application of thermal infrared remote sensing in land use/cover change monitoring

Land use/cover change refers to the changes in the spatiotemporal distribution of different types of land use and cover on land. Thermal infrared remote sensing can monitor changes in land use/cover by measuring spatial and temporal changes in surface temperature and radiation flux. According to the thermal infrared radiation characteristics of different types of land surfaces, land can be divided into different categories, and the impact of land use/cover changes on surface energy balance and ecological environment can be studied by monitoring changes in these categories.

Application of thermal infrared remote sensing in the study of urban heat island effect

The urban heat island effect refers to urban areas having higher temperatures relative to surrounding farmland and natural environments. Thermal infrared remote sensing can study and monitor the spatial distribution and changes of the urban heat island effect by measuring the surface temperature of urban areas. By analyzing the formation mechanism and influencing factors of the urban heat island effect, we can provide scientific basis for urban planning and construction to reduce the impact of the urban heat island effect on the sustainable development of the city and the quality of life of residents.

Application of thermal infrared remote sensing in agricultural production management

Thermal infrared remote sensing can study and monitor the effects of agricultural production management by measuring farmland surface temperature and crop evapotranspiration. By analyzing the thermal infrared radiation characteristics of farmland, agricultural production management indicators such as crop growth conditions, irrigation needs, and nitrogen use efficiency can be evaluated, thereby helping farmers make decisions and refined management, and improve agricultural production efficiency and resource utilization efficiency.

In summary, thermal infrared remote sensing has broad application value in land surface processes. Using thermal infrared remote sensing technology, we can have an in-depth understanding of the thermodynamic processes on the land surface, study land use/cover changes, monitor the urban heat island effect, and improve agricultural production management, which is important for protecting the ecological environment, maintaining sustainable urban development, and improving agricultural production. Benefits are of great significance.
