| Summary: | Datasets used in: Young, A.M., Higuera, P.E., Duffy, P.A., and F.S. Hu. Climatic thresholds shape northern high-latitude fire regimes and imply vulnerability to future climate change. In Review at Ecography as of 10/2015. ---------------------------------------------------------------------- ----------------------- Description ---------------------------------- ---------------------------------------------------------------------- These data are gridded maps of Alaska containing the projected 30-yr probabiltiy of fire occurrence for three different time periods in the 21st century: 2010-2039, 2040-2069, 2070-2099. We use downscaled GCM climate data under the RCP6.0 scenario. We provide projections for all 100 models for each of the three different spatial domains: AK, BOREAL, and TUNDRA. Gridded GCM data were processed and provided by the Scenarios Network for Alaska and Arctic Planning (https://www.snap.uaf.edu/). For further details regarding these archived data please refer to YOung et al. (In Review). ---------------------------------------------------------------------- ----------------------- Resolution ----------------------------------- ---------------------------------------------------------------------- Spatial Resolution: 2 km Temporal Resolution: Decadal Time Coverage: 2010-2099 ---------------------------------------------------------------------- ------------------------ File Naming --------------------------------- ---------------------------------------------------------------------- Example: AK_CCSM4_rcp60_pred_map_2010_2039_1.tif 'AK_' - Either models build for all of Alaska (AK), boreal forest only (BOREAL), tundra only (TUNDRA) 'CCSM4' - Specific GCM '_rcp60' - Climate change scenario '_pred_map' - predicted (or projected) 30-yr probabilities of fire occurrence [0-1].
