This master internship is dedicated to the creation of a semi-empirical emulator tool that reconstructs the spatial and temporal effects of land-cover changes (LCC) on surface temperature at global level.
Deforestation in boreal regions can progressively increase concentration of greenhouse gases and thus imply a biochemical warming but, at the same time, strongly increase the albedo, due to the presence of snow, which implies a biophysical cooling. Thus, the net effect of LCC on surface temperature depends on two categories of effects that can have opposite sign. The literature has only recently systematized the inclusion of biophysical effects and their estimates on temperature are still not consensual. However, it is of crucial importance to simulate correctly the effects of deforestation or the effects of reforestation projects on temperature, with different approaches and methodologies.
Bridging gaps between observational and climate modelling studies, the work will be shared in two phases providing an original and quantitative assessment of:
- Biogeochemical effects of LCC on temperature (ΔTBGC) that follow from a change in CO2, CH4, N2O greenhouse gases making efficient use of existing response functions of the recent literature.
- Biophysical effects of LCC on temperature (ΔTBPH) after linearization of surface energy balance equation using simple parametrizations and typical observational values for (i) albedo, (ii) roughness and (iii) latent/sensible heat fluxes of a given land cover.
In the framework of our LUC4C FP7 European project, the final products are expected to be valorized under the form of a publication and an emulator tool available for users with educational purposes and policy-makers.
