Estimating net surface longwave radiation from net surface shortwave radiation for cloudy skies

International Journal of Remote Sensing, 2013
This work addresses the estimation of net surface longwave radiation NSLR from net surface shortwave radiation NSSR by analysing the Surface Radiation Budget Network SURFRAD radiation data under cloudy conditions. A general model is developed to estimate NSLR from the NSSR for cloudy skies with a root mean square error RMSE of 23.16 W m−2 compared with

Net radiation and net long-wave radiation at Copenhagen 1962–1964

Archiv für Meteorologie, Geophysik und Bioklimatologie Serie B, 1967
Net radiation of short- and long-wave radiation has been recorded continuously during 1962–64 and monthly data are presented. Net long-wave radiation is determined as difference between recorded net short-wave and net total radiation. Net long-wave radiation has also been calculated according toMonteith [1] and close agreement was found between the two

AN IMPROVED NET-RADIATION INSTRUMENT

Journal of Meteorology, 1954
Abstract An improved net-radiation instrument for measuring the net flux of radiant energy through a surface parallel to the earth's surface, which employs the principle of exposing a ventilated radiation-absorbing element to the radiation sources, is described.

WeatherNet: Nowcasting Net Radiation at the Edge

2021 IEEE Conference on Technologies for Sustainability (SusTech), 2021
In addition to natural processes such as photosynthesis and evapotranspiration, net radiation affects industrial applications such as photovoltaic energy management and solar thermal collection. We propose a deep learning approach for nowcasting net radiation within subhourly and intrahour horizons to better understand and control processes influenced ...

ESTIMATION OF NET AND SOLAR RADIATION

Canadian Journal of Plant Science, 1971
Relationships between net radiation (QN) and global solar radiation (QS) and between the ratios of QS and solar radiation at the top of the atmosphere (QS/QA) and duration of bright sunshine and daylength (n/N) were determined by regression analysis at Guelph, Ontario, Canada. The data used were recorded at the Guelph O.A.C.

Net Thermal Radiation Under Shading Screens

Journal of Agricultural Engineering Research, 1995
A model for the prediction of nocturnal net thermal radiation, under a woven shading screen, stretched horizontally above the ground or forming a tunnel, is developed. A radiation transfer factor is defined and calculated for the cases of a triangular cross-section shading tunnel made of a woven screen and of a hemicylindrical shading tunnel. Radiation
