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

Estimation of Surface Net Radiation from Solar Shortwave Radiation Measurements

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
This study develops a method to estimate surface daytime net radiation (Rn) from solar shortwave radiation measurements with help of the conventional meteorological observations and vegetation indices from satellite. Data collected at twenty-two sites in the U.S.

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.

Solar radiation, net radiation and temperature in Argonne, Chicago

Solar Energy, 1973
Abstract Variations in the annual, seasonal and diurnal patterns of temperature and global and net radiation have been presented. Annual, seasonal and diurnal relationships between global and net radiation and between temperature and radiation have also been determined.

Solar and net radiation in Peninsular Malaysia

Journal of Climatology, 1983
AbstractLinear regression equations relating the global solar radiation and sunshine duration are derived for a total of 14 stations in Peninsular Malaysia. Mean monthly global solar radiation values for other stations which have only sunshine data are estimated using these regression equations.

Net radiation in plant stands

1981
Net radiation within a plant stand B(L) is the difference of all downward and upward fluxes of solar and long-wave radiation, i.e.

SOLAR RADIATION TRANSMISSION THROUGH PLASTIC SHADING NETS

Acta Horticulturae, 2012
Plastic shading nets are being used extensively in hot and sunny regions to protect plants from intense solar radiation. However, the choice of net to fulfill specific shading requirements often depends on empirical or economic criteria, not on scientific considerations because parameters used to characterize the different types of nets is not ...

Net radiation in a riparian mesquite community

Water Resources Research, 1969
Net radiation patterns for a riparian mesquite community are similar to net radiation patterns obtained for a humid forest. The net radiation peak of the open area was 61% of the net radiation peak above the canopy. The net radiation within a mesquite canopy peaked 9% higher but had a lower daily total value than the radiation above the canopy.

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 ...
