Answers to the reviewer comments on the manuscript “Diferent response of surface temperature and air temperature to the biogeophysical efects of deforestation in climate models” in Earth System Dynamics Discussions

Deforestation affects temperatures at the land surface and higher up in the atmosphere ::::::::::: Temperatures :::::: changes :::::::: following :::::::::: deforestation ::: are :::: well :::::::::: documented ::: but ::::::::::: considerable ::::::::: uncertainty ::::::: remains :::::::::: concerning :::: their :::::: precise ::::: value. :::: Part :: of ::: this :::::::::: uncertainty ::: may ::: be :::::: caused :: by ::: the ::: fact :::: that ::::::: different ::::::: methods :::: used :: to :::::::: quantify :::::::::: temperature ::::::: changes, ::: i.e., :::::::::::: satellite-based ::::::::::: observations, :::::: in-situ ::::::::::: observations, ::: and :::::: climate ::::::: models, ::::::: consider ::::::: different ::::::::::: temperatures. Satellite-based observations typically register deforestationinduced changes in surface temperature, in-situ observations register changes in near-surface air temperature, and climate 5 models simulate changes in both temperatures and the temperature of the lowest atmospheric layer. Yet a focused analysis of how these variables respond differently to deforestation is missing. Here, this is investigated :::::::: consistent ::::::::: comparison ::: of ::: the ::::::: response :: to ::::::::::: deforestation ::: for ::::::: different ::::::::::: temperature ::::::: variables :::: was ::::::: missing. :: In :::: this ::::: study ::: the :::::: effects :: of ::::::::::: deforestation :: on ::::::: surface :::::::::: temperature, :::::::::: near-surface ::: air :::::::::: temperature :::: and ::::: lower :::::::::: atmospheric :::::::::: temperature :::: are :::::::: compared : by analyzing the biogeophysical temperature effects of large-scale deforestation in the climate model ::::::::::::::::: Max-Planck-Institute ::::: Earth ::::::: System :::::: Model : (MPI-ESM, 10 : ) separately for local effects (which are only apparent at the location of deforestation) and nonlocal effects (which are also apparent elsewhere).

In agreement with observation-based studies, the local effects on surface and near-surface air temperature respond differently in the MPI-ESM, both concerning the magnitude of local temperature changes and the latitude at which the local deforestation effects turn from a cooling to a warming (at 45-55◦ N 15 for surface temperature and around 35◦ N for near-surface air temperature).
