A long-term decline in downward surface solar radiation [PDF]
National Science ReviewABSTRACT Downward surface solar radiation (DSSR) is critical for the Earth system. It is well-known that DSSR over land has fluctuated on decadal timescales in the past. By utilizing a combination of station observations and the latest CMIP6 simulations, here we show that DSSR had a global consistent decline during 1959–2014, with ...

Computation of irradiance in a solar still by using a refined algorithm [PDF]
, 2013 A refined solar algorithm from the ESP-r system has been used to calculate the distribution of solar irradiation inside a basin-type solar still. In the approach, surface finish, view factors and multiple reflections are taken into consideration in the ...

Self-Sustaining Hybrid Passive Cooler Enabling Highly Effective Thermal Management for Outdoor Electronics. [PDF]
Adv Sci (Weinh)An innovative hybrid passive cooler integrates a porous radiative coating and an atmospheric moisture‐harvesting hydrogel within a melamine sponge skeleton, synergizing radiative cooling, sensible‐heat absorption, and latent‐heat evaporation. It maintains an average 8.3°C sub‐ambient cooling under sunlight and a maximum ∼42.4°C drop under 2000 W·m−2 ...

Bridging Horizontal to Vertical Radiative Cooling. [PDF]
Adv Sci (Weinh)Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Solar radiation incident on the Martian surface [PDF]
Journal of Molecular Evolution, 1979 Calculations indicate that the maximum daily solar radiation reaching the Martian surface is about 325 cal/cm2 during southern hemisphere summer at latitude of about 40 degrees S. In the ultraviolet region of the spectrum, the radiation reaching the surface at wavelengths greater than 2800 A is within 10% of the radiation incident on the atmosphere ...

Solar Radiation on a Parabolic Concave Surface [PDF]
Energies, 2021 Curved structures are used in buildings and may be integrated with photovoltaic modules. Self-shading occurs on non-flat (curved) surface collectors resulting in a non-uniform distribution of the direct beam and the diffuse incident solar radiation along the curvature the surface.

Visibility and potential of solar energy on horizontal surface at Kuwait Area [PDF]
, 2011 In this paper, an overview of the production and consumption of Kuwait electrical energy, installed capacity and peak loads are presented. The results show that Kuwait has a serious situation because of the electrical energy lacking and load peaking ...

Effects of Aerosols and Clouds on the Levels of Surface Solar Radiation and Solar Energy in Cyprus [PDF]
Remote Sensing, 2021 Cyprus plans to drastically increase the share of renewable energy sources from 13.9% in 2020 to 22.9% in 2030. Solar energy can play a key role in the effort to fulfil this goal. The potential for production of solar energy over the island is much higher than most of European territory because of the low latitude of the island and the nearly cloudless
