Treeline Maps - ALFRESCO Model Outputs - Linear Coupled

These are map products depicting modeled treeline dynamics. The left panel indicates modeled treeline dynamics from a single 2014 baseline year to the year 2100. The right panel indicates basal area accumulation on a 1km x 1km pixel basis during the year 2100, which gives an indication where possible further treeline advance may occur beyond 2100.

The source dataset used to create these maps can be found here:

ALFRESCO is a landscape scale fire and vegetation dynamics model. These specific outputs are from the Integrated Ecosystem Model (IEM) project, and are from the linear coupled version using CMIP3 climate inputs (IEM Generation 1a).

These outputs include data from model rep 171, referred to as the “best rep” out of 200 replicates. The best rep was chosen through comparing ALFRESCO’s historical fire outputs to observed historical fire patterns. Single rep analysis is not recommended as a best practice, but can be used to visualize possible changes.

The IEM Generation 1 is driven by outputs from 2 AR4/CMIP3 climate models, and one emission scenario. The models include: cccma_cgcm3_1 and mpi_echam5, under the A1B emission scenario.
