T]) is a nondimensional ratio of the amount of clear sky radiation that hits a horizontal surface ([[.
The clear sky radiation on horizontal surface values were obtained with the use of the models proposed by Hottel and the model proposed by Liu and Jordan, as cited by Duffie and Beckman (2006).
In a typical house, the roof area is large with high exposure to solar gain and night sky radiation, with minimal vapor control separation to the interior space.

Our proposal is to improve sensitivity by using sensors with organic compounds that aresensitive to background sky radiation (1.

3) Long-wave sky radiation toward the upper leaf surface [L.
d] = long-wave downward sky radiation under clear sky (W/[m.
In passive systems, such as FLIRs or mm-wave radiometers, radiation from the runway and its surroundings, including reflected sky radiation, traverses a section of the atmosphere on its way to the sensor and in the process experiences a reduction in its intensity.
In fact, cloud cover has a strong influence on sky radiation (Mills 1995).
Finally, for selected models, a comparison of hourly sky radiation exchange from a horizontal surface is provided.
The sky temperature used to calculate the sky radiation was assumed to be 10[degrees]C (18[degrees]F) below that of the ambient temperature, and that the panel's emissivity would be valid for both the long wave radiation leaving and entering it.
