A derived diurnal mean CRF, solved as a function of solar zenith angle, θ, though varied over the solar day, is used to evaluate the sensitivity and influence of θ on CRF calculations. Although a total mean net (NET) CRF of 36.5 ± 48.4 W m&#8315², estimated using direct observation data, is approximately equal to the value of 36.8 ± 50.4 W m&#8315² from the diurnal mean simulations, monthly differences illustrate a seasonality function dictating the influence of θ on CRF. A significant positive NET effect exceeding similar to 80 W m&#8315² over the Qinghai-Tibet Plateau is found, which is in contrast to a NET CRF found to be closer to 20 W m&#8315² for most parts of China. This finding is attributable to a more prominent warming effect of cirrus clouds observed over higher terrain. Furthermore, a warmer and more humid thermal profile over the high terrain in summer induces decreases in longwave (LW) and NET CRF over the plateau. The seasonal spatial variability of cirrus cloud visible optical depths also contributes to the corresponding spatial variability of shortwave (SW), LW, and NET CRF solved.
