The Pseudo Radiation Energy Amplifier (PREA) and the mean earth s ground temperature
Ahmed Boucenna

TL;DR
This paper introduces the concept of the Pseudo Radiation Energy Amplifier (PREA) to explain the Earth's mean ground temperature, reconciling the discrepancy between theoretical black body radiation calculations and observed temperature.
Contribution
It proposes that Earth acts as a PREA, a gray body with specific reflection properties, which explains its higher observed mean temperature compared to classical black body models.
Findings
Earth's mean temperature estimated at 15°C.
Black body radiation theory predicts -18°C.
Reflection coefficients significantly influence Earth's climate.
Abstract
From the radiation balance diagram illustrating the IPCC reports one can estimate the power received by Earth from the sun at Pin = 342 W/m2 and the power consumed, remitted and reflected by the earth and its atmosphere at Pout = 599 kW/m2. It seems that the earth emits more power than it receives. The earth s ground mean temperature is estimated at 15 C. A calculation based on the black body radiation theory gives an earth s ground mean temperature of the order of -18 C which is much lower than 15 C. The important gap between these calculated and estimated temperature mean values requires an explanation. Here we show that a gray body separated from vacuum by an interface and submitted to outside incident radiation can behave like a Pseudo Radiation Energy Amplifier. The Earth which is a gray body separated from the space by an interface, behaves like a Pseudo Radiation Energy…
