Multi-layer wind velocity field visualization in infrared images of clouds for solar irradiance forecasting
TL;DR: This article investigates how to infer multiple wind velocity fields using consecutive longwave infrared (IR) images of clouds to forecast the occlusion of the Sun by clouds.
Journal ArticleDOI
Girasol, a sky imaging and global solar irradiance dataset
TL;DR: In this paper, the Girasol Machine (Girasol means Sunflower in Spanish) is proposed to forecast Global Solar Irradiance (GSI) using a data acquisition system (DAQ) that simultaneously records sky imaging and GSI measurements, with the objective of extracting features from clouds and use them to forecast the power produced by a Photovoltaic (PV) system.

Solar Irradiance Nowcasting for Virtual Power Plants Using Multimodal Long Short-Term Memory Networks
Dilantha Haputhanthri,Daswin De Silva,Seppo Sierla,Damminda Alahakoon,Rashmika Nawaratne,Andrew Jennings,Valeriy Vyatkin +6 more
TL;DR: In this paper, a multimodal approach is proposed based on two Long Short-Term Memory Networks (LSTM) that receives a temporal image modality of a stream of sky images, a time-series of past solar irradiance readings and cloud cover readings as inputs for irradiance nowcasting.

Thermal radiation heat transfer
Robert Siegel,John R. Howell +1 more
TL;DR: In this article, a comprehensive discussion of heat transfer by thermal radiation is presented, including the radiative behavior of materials, radiation between surfaces, and gas radiation, and the use of the Monte Carlo technique in solving radiant exchange problems and problems of radiative transfer through absorbing-emitting media.
