An analytical model for daily‐periodic slope winds. Part 1: Surface radiation budget

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 150, Issue 764, Page 3911-3924, October 2024 Part A.
The article presents an analytical model for evaluating representative daily‐periodic cycles of net surface radiation on a slope with any angle α$$ \alpha $$ (0∘≤α≤90∘$$ {0}^{\circ}\le \alpha \le 9{0}^{\circ } $$) and orientation, at any latitude and elevation (up to 2500 m), and for all seasons.

Attributing Urban Evapotranspiration From Eddy‐Covariance to Surface Cover: Bottom‐Up Versus Top‐Down

open access: yesWater Resources Research, Volume 60, Issue 9, September 2024.
Abstract Evapotranspiration (ET) $(ET)$ is a key process in the hydrological cycle that can help mitigate urban heat. ET $ET$ depends on the surface cover, as the surface affects the partitioning of precipitation between runoff and evapotranspiration. In urban neighborhoods, this surface cover is highly heterogeneous.

Monitoring and modeling of the urban micro-climate [PDF]

open access: yes, 2013
Urban heat island phenomenon (UHI) is considered to be one of the major challenges encountered this century by the human kind. This phenomenon is characterized mainly by air temperatures in the city that are higher than those in the surrounding areas ...

FLApy: A Python package for evaluating the 3D light availability heterogeneity within forest communities

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 9, Page 1540-1552, September 2024.
Abstract Light availability (LAv) dictates a variety of biological and ecological processes across a range of spatiotemporal scales. Quantifying the spatial pattern of LAv in three‐dimensional (3D) space can promote the understanding of microclimates that are critical to fine‐scale species distribution.

Sky view factor measurement by using a spherical camera

open access: yesJournal of Agricultural Meteorology, 2019
Sky view factor (SVF) is a ratio of sky in upper hemisphere and is an important index for many environmental studies. Frequently used method for measuring SVF is taking fisheye image of upper hemisphere by a camera with fisheye lens (Nikon FC-E8 and FC ...

Diurnal asymmetry in nonlinear responses of canopy urban heat island to urban morphology in Beijing during heat wave periods [PDF]

open access: yesAtmospheric Chemistry and Physics
Currently, the diurnal asymmetric and nonlinear mechanisms by which urban morphology modulates the canopy urban heat island (CUHI) during heat wave (HW) periods remain underexplored.

The 3dskyview extension: an urban geometry access tool in a geographical information system [PDF]

open access: yes, 2003
Implemented as a tool in a 3D Geographical Information System (GIS), the 3DSKYVIEW Extension introduced here calculates sky view factors values, while generating its graphical representation on both 2D and 3D scenes.

Spatial and Temporal Effects of Built Environment on Urban Air Temperature in Seoul City, Korea: An Application of Spatial Regression Models [PDF]

open access: yes, 2017
In this study we examined the relationships between the built environment and urban air temperature in Seoul city, Korea. We developed multivariate regression models that address the relationship between built environment characteristics and the ambient ...

Sky view factor as predictor of solar availability on building façades

open access: yesSolar Energy, 2018
Solar availability on urban facades varies significantly, affected by obstructions by nearby buildings as well as orientation. A convenient way to evaluate their solar energy potential is deemed to facilitate the task of architects in increasing the use ...
