Photothermal Membrane Water Treatment for Two Worlds.

TL;DR: This Account introduces the recent work on developing scalable, cost-effective, and highly efficient photothermal membranes for four water purification applications, and develops membranes for PMD that incorporate photothermal materials to generate heat under solar irradiation, thus providing a higher transmembrane temperature difference and higher driving force for effective vapor transport, making the membrane distillation process more energy-efficient.

The role of clouds in improving the regression model for hourly values of diffuse solar radiation

TL;DR: In this paper, a new regression model was developed to estimate the hourly values of diffuse solar radiation at the surface, which is based on the clearness index and diffuse fraction relationship.

Simple Solar Spectral Model for Direct and Diffuse Irradiance on Horizontal and Tilted Planes at the Earth's Surface for Cloudless Atmospheres

TL;DR: In this paper, a simple model for calculating direct normal and diffuse horizontal spectral solar irradiance for cloudless sky conditions was described. But the model was developed using rigorous radiative transfer codes and limited outdoor measurements.

- 01 Feb 1984 - 
TL;DR: In this paper, the authors presented a merging of the absolute integrals of the disk-center intensity for 20 A wide spectral bands and the ratios of mean to central intensity derived from recent observations of the center-to-limb variation of those bands (λ 6600 A).

Parameterized transmittance model for direct beam and circumsolar spectral irradiance

Christian A. Gueymard
- 01 Nov 2001 - 
TL;DR: In this article, an upgraded spectral radiation model called SMARTS2 (Simple Model of the Atmospheric Radiative Transfer of Sunshine) is introduced, based on spectral transmittance functions for the main extinction processes in the cloudless atmosphere: Rayleigh scattering, aerosol extinction, and absorption by ozone, uniformly mixed gases, water vapor, and nitrogen dioxide.
