Abstract

An important variable to calculate local temperatures is the Sky View Factor (SVF) which is the fraction of sky visible from the ground. The SVF depends on the height of the obstacles in the surroundings of a given location. The goal is to capture small features like houses and trees throughout the Netherlands at a very high resolution. This dataset comprises the Sky View Factor of The Netherlands at 0.5 meter resolution raster based on Actual Height Model of the Netherlands (AHN2) elevation dataset.

Supplemental information Title Sky View Factor of The Netherlands DIO for scientific and technical background https://doi.org/10.1016/j.uclim.2019.100498 Citation Dirksen, M., Ronda, R. J., Theeuwes, N. E., & Pagani, G. A. (2019). Sky view factor calculations and its application in urban heat island studies. Urban Climate, 30, 100498. https://doi.org/10.1016/j.uclim.2019.100498 Description The sky view factor (SVF) is essential to describe the urban climatology at scales below 100m. This proxy for net radiation depends on the height of the obstacles in its surroundings. Since global radiation the major forcing of diurnal temperature range the SVF is often used in urban heat island studies. The SVF was calculated from a rasterized point cloud height dataset (with 6-10 points per m2)*. At this scale small features like houses and trees throughout the Netherlands are captured. *Version 3 was based on the official PDOK 0.5m AHN2 raster
