Separating the impact of individual land surface properties on the terrestrial surface energy budget in both the coupled and uncoupled land–atmosphere system

Changes in the land surface can drive large responses in the atmosphere on local, regional, and global scales. Surface properties control the partitioning of energy within the surface energy budget to fluxes of shortwave and longwave radiation, sensible and latent heat, and ground heat storage. Changes in surface energy fluxes can impact the atmosphere across scales through changes in temperature, cloud cover, and large-scale atmospheric circulation. We test the sensitivity of the atmosphere to global changes in three land surface properties: albedo, evaporative resistance, and surface roughness. We show the impact of changing these surface properties differs drastically between simulations run with an offline land model, compared to coupled land–atmosphere simulations that allow for atmospheric feedbacks associated with land–atmosphere coupling. Atmospheric feedbacks play a critical role in defining the temperature response to changes in albedo and evaporative resistance, particularly ..., Simulations with the CESM model coupled to a simple land model as described in Laguë et al. 2019 linked here., , # **Separating the impact of individual land surface properties on the terrestrial surface energy budget in both the coupled and uncoupled land–atmosphere system**

This dataset contains climate model simulations using the CESM-SLIM model as described in Laguë et al. 2019.

## Description of the data and file structure

There are 13 experiments with different combinations of uniform land surface properties. For each experiment there is one tarball for land output, and one tarball for atmospheric output. Within each tarball are netcdf files which each contain one variable. The name and unit for each variable are listed in the metadata of the netcdf files.

The naming convention for the experiments is as follows:

a1 = albedo of 0.1

a2 = albedo of 0.2

a3 = albedo of 0.3

hc represents the effective vegetation height for aerodynamic roughness, with experiments for values of 0.01, 0.05, 0.1, 0.5, 1.0, 2.0, 5.0, 10, and 20.0

rs represents surface resistance to evaporation, with experime...
