Net Radiation Flux The net radiation (Rn) would be the difference among the downwards and upwards radiation fluxes in the ground surface. In the absence of other modes of heat exchange, the surface temperature increases when the net radiation is optimistic; remains constant when the net radiation is zero; and decreases when the net radiation is adverse. Net radiation is jointly determined by every single component of the radiation balance, and thus is impacted by solar altitude angle, atmospheric transparency, altitude, underlying surface conditions, etc. [35]. The inter-annual variations in net radiation (Figure 20) ranged amongst 50 W -2 and 140 W -2 , with an overall escalating trend at each and every station. Despite the fact that the downward shortwave radiation showed decreasing trends at BJ and NAMORS, the upward shortwave radiation reflected by the ground surface also decreased. This was as a (Z)-Semaxanib supplier consequence of rising vegetation cover (Figure 10). Though the upward longwave radiation showed an escalating trend, the downward longwave radiation also enhanced. All round, the net radiation showed an rising trend. At QOMS, the upward shortwave radiation decreased, the downward longwave radiation elevated. As a result, the net radiation showed an increasing trend. At NADORS, the downward shortwave radiation showed small transform, the upward shortwave radiation decreased, along with the downward longwave radiation improved. Thus, the net radiation showed an growing trend.
