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

Empirical estimation of daytime net radiation from shortwave radiation and ancillary information
Agricultural and Forest Meteorology, 2015 All-wave net surface radiation is greatly needed in various scientific research and applications. Satellite data have been used to estimate incident shortwave radiation, but hardly to estimate all-wave net radiation due to the inference of clouds on ...

Net Radiation Studies in the Schefferville Area
ARCTIC, 1963 Describes summer 1961 radiation measurements in northern Quebec - Labrador. The study was made (methods noted) to test a correlation established by Orvig (No. 74547) from data obtained in 1958, viz a correlation coefficient of 0.777 between the mean daytime net flux and the daily total short-wave radiation.

Uncertainty assessment of surface net radiation derived from Landsat images [PDF]
Remote Sensing of Environment, 2016 The net radiation flux available at the Earth's surface drives evapotranspiration, photosynthesis and other physical and biological processes. The only cost-effective way to capture its spatial and temporal variability at regional and global scales is ...

Net radiation and net long-wave radiation at Copenhagen 1962–1964
Archiv für Meteorologie, Geophysik und Bioklimatologie Serie B, 1967Net 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, 1954Abstract 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, 1971Relationships 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.

The calculation of the net radiation flux
Archiv für Meteorologie, Geophysik und Bioklimatologie Serie B, 1980A 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 ...

WeatherNet: Nowcasting Net Radiation at the Edge
2021 IEEE Conference on Technologies for Sustainability (SusTech), 2021In 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 ...

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-
