Splet01. maj 2024 · The incoming solar radiation flux which is a radiant energy, is the sum of the diffused (the incoming shortwave in the shade) and direct radiations incident on the earth's surface in the form of shortwave radiation. This energy is the major means and primary source of energy that drives the hydrological cycle (Iqbal, 1983; Geiger et al., 1995). Splet01. sep. 2024 · Radiative energy flux data, downloaded from CERES, are evaluated with respect to their variations from 2001 to 2024.
