Impact of Sky View Factor on Outdoor Thermal Comfort

Cities are vulnerable to temperature changes due to the inappropriate urbanization process causing Urban Heat Island effect, which exacerbates the instability of the thermal environment and the risk of human heat exposure. The 2021 IPCC Sixth Assessment Report indicates a 1.09°C rise in global average temperature from 2011 to 2020, along with increased

Influence of sky view factor on outdoor thermal environment and physiological equivalent temperature

International Journal of Biometeorology, 2014
Sky view factor (SVF), which is an indicator of urban canyon geometry, affects the surface energy balance, local air circulation, and outdoor thermal comfort. This study focused on a continuous and long-term meteorological observation system to investigate the effects of SVF on outdoor thermal conditions and physiological equivalent temperature (PET ...

Radiative Coupling towards Sky and Ground (External View Factor)

2010
A significant radiative coupling can occur between the outer surfaces of a telescope, and enclosure, and the sky and the ground. This radiative coupling is illustrated in Fig. 8.1 for the IRAM 30-m telescope. In the left picture, the telescope is at horizon position so that the upper part of the reflector surface sees the warmer ground while the lower ...

Influence of multi path on positioning accuracy in a low sky view factor environment

2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017
Recently, utilization of position information by global navigation satellite system (GNSS) is expected in various fields. However, it's difficult to show unambiguously accuracy since positioning accuracy varies by measurement environment. We bring sky view factor (SVF) to evaluation of positioning accuracy, and evaluate it positioning accuracy of long ...

Object‐based Shell Craters Classification from LiDAR‐derived Sky‐view Factor

Archaeological Prospection, 2016
AbstractThis paper presents the results of the first attempt to assess, identify and quantify the residual number of shell craters of World War I currently present in the Vezzena/Luserna/Lavarone Plateau, areas of Millegrobbe, Bisele and Cima Campo (Province of Trento, Italy).

A method to estimate sky view factors from digital elevation models

International Journal of Climatology, 2012
AbstractSky view factor (SVF) is a commonly used parameter in atmospheric sciences. A method how to obtain an approximate value of SVF from digital elevation models (DEM) is described. The method takes into account slopes and transmittance of objects and is able to compute SVF for complex geometries (e.g.
