Extension of Approximate Partial Radiative Perturbation (APRP) method
Programming language : matlab
Field : climate science
Main purpose : Decomposition of radiative flux changes in GCMs (General Circulation Models)
Description :
Originally, APRP method is used to attribute the change in SW fluxes at TOA (Top Of Atmosphere) to the change in surface albedo, cloud properties, and non-cloud properties. (Taylor et al. 2007 : https://journals.ametsoc.org/view/journals/clim/20/11/jcli4143.1.xml)
Here, I extend the original APRP method for TOA to the surface, by using the one-layer radiation model.
albedo.m and incident_sw_ratio.m have to be in the same path with aprp_extension_hjkim.m to use the aprp function
Note that the variations of one-layer radiation model are possible with function argument "flag_model", "ar", "rr". Refer to Appendix A of below paper and attached PDF for the detailed explanation.
