Estimation of Surface Net Radiation from Solar Shortwave Radiation Measurements
IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008This 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, 1968A 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.

Transactions of the ASABE, 2010
We compared daily net radiation (Rn) estimates from 19 methods with the ASCE‐EWRI Rn estimates in two climates: Clay Center, Nebraska (sub‐humid) and Davis, California (semi‐arid) for the calendar year. The performances of all 20 methods, including the ASCE‐EWRI Rn method, were then evaluated against Rn data measured over a non‐stressed maize canopy ...

Solar radiation, net radiation and temperature in Argonne, Chicago
Solar Energy, 1973Abstract 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, 1983AbstractLinear 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.

A Comparison of Solar Radiation and Net Radiation 1, 2
Bulletin of the American Meteorological Society, 1956Daily values of solar and net radiation at Ames, Iowa were compared for the period, late June through November, 1954. It was found that by dividing the data into two groups, clear days and cloudy days, regression lines could be computed which fitted the data very well.

A note on the relationship between net radiation and solar radiation
Quarterly Journal of the Royal Meteorological Society, 1967AbstractLinear relationships between daytime net radiation (Rn) and solar radiation (Q) have been determined for West Africa and for selected stations throughout the world. For three West African stations.Rn = 0·612 Q −28And for fourteen stations throughout the worldRn = 0·617 Q −24Where Rn and Q are in g cal cm−2 day−1.The surfaces represented have ...

ON THE OBSERVATION OF TOTAL AND NET ATMOSPHERIC RADIATION
Journal of Meteorology, 1960Abstract Simultaneous night observations with four different sensors for the long-wave atmospheric radiation were obtained with a radiosonde, specially equipped for this purpose. The sensors consisted of (1) a radiometersonde as developed by Sumoi and Kuhn, (2) a disc-type total radiometer, and (3) two spherical total radiometers (i.e., a ‘black ball ...

Net radiation in a riparian mesquite community
Water Resources Research, 1969Net 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.
