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

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

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.

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.

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 radiation for a coniferous forest, and the effects of logging on net radiation and the reflection coefficient

Canadian Journal of Forest Research, 1978
The results of field studies on the radiation climate at Montmorency, Quebec, are presented. These studies were conducted in the summers of 1975 and 1976, and two sites were used. The first site, used in both years, was forested with 50- to 60-year-old balsam fir (Abiesbalsamea L. Mill.). The second site, originally forested with balsam fir, was clear-

The calculation of the net radiation flux

Archiv für Meteorologie, Geophysik und Bioklimatologie Serie B, 1980
A comparison between two global solar radiation- and two net longwave radiation flux formulas applied to the calculation of the net radiation flux was made. The differences between the two global solar radiation formulas were fairly small but the ratio of the two net longwave radiation formulas varied from approximately 1.21 under cloudless conditions ...

Estimating the net-radiation flux

Agricultural Meteorology, 1968
A major influence controlling the water loss from irrigated crops is the net-radiation intensity Qn, but measurements of this are not normally available, and so attempts are often made to deduce it from other climatic data, such as the solar-radiation.
