Land Surface Temperature (LST) is an extremely important parameter that controls the exchange of longwave radiation and sensible heat flux between the Earth’s surface and the atmosphere. Therefore knowledge of LST is essential for a range of issues and themes in Earth sciences central to hydrology, climatology and global environmental change. In particular, it plays a main role in estimating hydrological variables, such as evapotranspiration. However, because of the extreme heterogeneity of most natural land surfaces, LST is a difficult parameter to estimate and to validate.

The knowledge of land surface temperature (LST) is of great importance, because it helps us to understand processes such as energy exchange between surface and atmosphere, water requirements in agricultural soils, control and prevention of fires and the evolution of climate change. Also, we need to try to know its value with enough accuracy. Two important factors are taken into account: the surrounding environmental conditions on the surface and its own emissivity.
