Methodological dependencies of cloud radiative forcing for the Canadian Climate Centre second‐generation general circulation model

Clear‐sky fluxes at the top of the atmosphere (TOA) are essential for calculating cloud radiative forcings (CRF). Both sets of quantities have been computed by three different methods using data from the Canadian Climate Centre general circulation model (CCC‐GCM) (simulations of July 1985 and January 1986). The methods differ in the way they compute monthly mean clear‐sky fluxes at the TOA ( ). The first method, known as method 2, is ideal for …
