The Israel–Egypt border region composed of longitudinal sand dunes is a very unique arid environmental ecosystem in the world: the Israeli side with much more vegetation cover has notably higher land surface temperature (LST) during daytime than the Egyptian side where bare sand prevails. In order to understand this thermal anomaly and its scientific significance in the arid environmental ecosy...

The imaging spectrometer VIRTIS is the flight spare of the instrument of the same name on the Rosetta mission. It was refitted to be part of the Venus Express mission orbiting Venus since 2006. VIRTIS can observe nightside thermal emissions at the wavelengths of several atmospheric windows. In three of these windows atmospheric transparency is sufficient to allow a measurable amount of radiatio...

This paper uses the refined Generalized Split-Window (GSW) algorithm to derive the land surface temperature (LST) from the data acquired by the Visible and Infrared Radiometer on FengYun 3B (FY-3B/VIRR). The coefficients in the GSW algorithm corresponding to a series of overlapping ranges for the mean emissivity, the atmospheric Water Vapor Content (WVC), and the LST are derived using a statist...

The higher concentration of man-made objects like asphalt pavement and concrete structures within urban areas lead to the formation of subareas known as urban heat islands (UHI), where the ambient temperature is significantly higher. Having a good understanding of this problem is critical for better urban development. Thermal infrared (TIR, 8-12 μm) remote sensing is often used to localize UHI....

[1] In the near‐infrared from about 2 mm to beyond 3 mm, the light from the Moon is a combination of reflected sunlight and emitted thermal emission. There are multiple complexities in separating the two signals, including knowledge of the local solar incidence angle due to topography, phase angle dependencies, emissivity, and instrument calibration. Thermal emission adds to apparent reflectanc...

This paper discusses the possibility of increasing the energy performance of thermal brick through integration with two different technologies: the first is based on the insertion of phase change material (PCM) inside the enclosures of the bricks, while the second involves covering the internal surface of the enclosures with low emissivity coating. PCM was employed to increase the thermal mass ...

Surface emissivity is a measure of inherent efficiency of land surface. It is applied to convert heat energy into radiant energy. In this study, an unmixing pixel based algorithm was proposed to compute pixel effective emissivity for Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data within Beijing, China. In this paper, vegetation, together with water and 3 kinds of ma...

This paper presents modifications to the linear kernel bidirectional reflectance distribution function (BRDF) models from Roujean et al. and from Wanner et al. that extend the spectral range into the thermal infrared (TIR). Our application is to synthesize the TIR optical properties of a scene pixel from laboratory component measurements. The angular reflectance and emissivity are needed to con...

Different parameters influence the results of infrared measurements of temperature. The emissivity of the surface under consideration as well as the temperature of the ambient elements may be specified among these parameters. Convective and radiative heat transfer takes place between thermal pipelines and its surrounding. In the case of low temperature of the sky, the radiation heat exchange is...

Semi-opaque to opaque films containing small amounts of various aluminium particles to decrease emissivity were easily prepared and coated onto low-density polyethylene (LDPE) sheets. The thermal-radiative properties (reflectivity, transmissivity and absorptivity) of the films were measured and related to the aluminum particles' content, size and nature. Time-to-ignition of samples was assessed...
