This dataset contains output files from single-point Community Land Model simulations with the hillslope hydrology configuration run by Katya Jay for the manuscript titled 'Plant functional trait uncertainty outweighs climate change uncertainty in tundra ecosystems.’ Local observations from Niwot Ridge, CO were used to force and evaluate these simulations to represent alpine tundra vegetation across a moisture gradient. 

The control simulations were modified to represent a site at Niwot Ridge referred to as the 'Saddle', with an east and west facing knoll and a lowland area between them. Three columns represent distinct moist, wet, and dry meadow vegetation communities. We used the same model setup to run additional experiments where we modified sets of parameters (specific leaf area, leaf C:N, and d13C) for each community to represent more resource use acquisitive or conservative growth strategies that could occur with warming temperatures. Simulations were run using input data from 2008-2021 (historical) and then extended to year 2100 (future) using an anomaly forcing protocol. There are separate folders containing results from each experiment titled: ‘NEON_NIWO_saddle_updated_snow_soils_H2OSFC_expt3_micro_sigma’ = control spinup, ‘NEON_NIWO_saddle_updated_snow_soils_H2OSFC_expt3_micro_sigma_trans’ = control transient (2008-2021), ‘NEON_NIWO_saddle_updated_SSPxxx’ = control future (2022-2100) under two different SSP scenarios; ‘NEON_NIWO_saddle_updated_TraitExp1.1_SSPxxx’ = acquisitive trait experiment (2022-2100) under two different SSP scenarios; ‘NEON_NIWO_saddle_updated_TraitExp1.3_SSPxxx’ = conservative trait experiment (2022-2100) under two different SSP scenarios.
