Abstract
The cloud radiative forcing (CRF) plays an important role in the climate system for physical, dynamical, chemical and biological processes. The CRF value effects the overall and the distribution of energy between the atmosphere and the surface. In this study, the CRF value is analyzed from one-layer to consider in two-layer cloud by adding the cloud between the top of atmosphere (TOA) and the cloud at one-layer. There are three experiment cases of longwave, shortwave and net two-layer cloud radiative forcing. The results show that the CRF value depends on cloud optical depth and cloud top altitude of each layer in case of longwave. The CRF value depends on only cloud optical depth of each layer on a case of shortwave. In net CRF, the CRF value depends on the cloud optical depth and cloud top altitude of each layer. The CRF value depends on the low-cloud more than high-cloud. For all cases, the results can be concluded that the CRF values of two-layers CRF model give the similar results compared with the radiative transfer model. ฉ 2006-2019 Asian Research Publishing Network (ARPN).
