Climate model experiments of regional-scale tree die-off replaced by grass (select variables at daily time resolution): Part 2

Climate change is triggering regional-scale alterations in vegetation including land cover change such as forest die-off. At sufficient magnitudes, land cover change from forest die-off in one region can change not only local climate but also vegetation including agriculture elsewhere via changes in larger scale climate patterns, termed an ‘ecoclimate teleconnection’. Ecoclimate teleconnections can therefore have impacts on vegetative growth in distant regions, but the degrees to which the impact decays with distance or directionally diffuses relative to the initial perturbation are general properties that have not been evaluated. We used the Community Earth system model to study this, examining the implications of tree die-off in 14 major US forested regions. For each case we evaluated the ecological impact across North America as a function of distance and direction from the location of regional tree die-off. We found that the effects on gross primary productivity (GPP) generally deca..., This dataset is a selection of variables at daily time resolution.
These data are climate model output from experiments described further in the relate manuscrip by Feng et al. Briefly, we conducted simulations using National Center for Atmospheric Research (NCAR) Community Earth System Model version 1.3 (CESM, https://www.cesm.ucar.edu/models(opens in new window)). The CESM model couples Community Atmosphere Model version 5 (CAM5) (Neale et al 2012) to the Community Land Model (CLM4.5) (Oleson et al 2013), the CICE4 sea ice model (Hunke et al 2010), and implements a slab ocean with prescribed heat transport derived from a fully-coupled ocean-atmosphere simulation (Neale et al2012). Further details about the parameterization of the component models can be found in the papers above, as well as in the technical documentation (Oleson et al 2013). Year 2000 land use conditions based on satellite observations (Lawrence and Chase 2007) were used in the model setup, and the atmospheric CO2 con..., , # Climate model experiments of regional-scale tree die-off replaced by grass (select variables at daily time resolution): Part 2

This dataset is ***part 2*** of a collection of four datasets related to the same study:

Part 1: Contains all variables from simulations where trees were replaced with C3 grass, at a monthly averaged time resolution. It also includes time series for the specific variables plotted in the accompanying Feng et al. publication in Environmental Research Letters (ERL) [[https://doi.org/10.5061/dryad.stqjq2c8j](https://urldefense.com/v3/__https://doi.org/10.5061/dryad.stqjq2c8j__;!!K-Hz7m0Vt54!i7nYlnE0GWoD-8XfyK6avWBoTt0vp31R7NQgXopp8HyuY-G31AoFz_Aqu8pgLWEx_mVa_SltTOmy$)].

Part 2: Contains selected variables from simulations where trees were replaced with C3 grass, at a daily time resolution [[https://doi.org/10.5061/dryad.z8w9ghxqr](https://urldefense.com/v3/__https://doi.org/10.5...,
