View Factors of Flat Collectors, Including Photovoltaics, Visible to Partial Sky

Energies, 2022
The sky view factor of collectors in photovoltaic (PV) fields is a parameter that determines the amount of incident diffuse radiation. The diffuse radiation may contribute significantly to the generated electric energy.

Street view-derived city built environment and vulnerability to temperature extremes: a nationally representative population-based cohort study [PDF]

BMC Medicine
Background The city built environment plays a crucial role in influencing population vulnerability to temperature extremes, yet population-based evidence has been limited. Methods We included 21,494 urban residents from a nationally representative cohort

Assessment of overhead environments on pedestrian thermal comfort in a dense urban district [PDF]

E3S Web of Conferences, 2023
Outdoor thermal comfort in urban environmental settings is often investigated at a small scale, e.g., in street canyons. Yet, pedestrian thermal comfort in a district is scarcely assessed, especially in terms of the comprehensive overhead environments ...

View Factors in Horizontal Plane Fixed-Mode Solar PV Fields

Frontiers in Energy Research, 2022
In solar PV fields, solar photovoltaic panels are typically arranged in parallel rows one after the other. This arrangement introduces variations in the distribution of solar irradiance over the entire field, compared to measurements recorded at ...

Analysis of Aerosol Optical Depth and Forward Scattering in an Ultraviolet Band Based on Sky Radiometer Measurements

Remote Sensing, 2023
The sky-radiometer/sun-photometer is the most widely used instrument for obtaining aerosol optical depth (AOD) or aerosol optical properties worldwide. Due to the existence of field of view (FOV, 1°), the radiation received by the sky-radiometer includes

Model for computation of solar fraction in a single-slope solar still [PDF]

, 2009
A new model that calculates the distribution of solar radiation inside a single-slope solar still has been proposed. In this model, the solar fraction on a vertical surface is divided into beam and diffuse parts and the optical view factors of surfaces ...
