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 historical and future downscaled climate data. Specifically, there are maps of monthly (1) temperature and (2) total precipitation minus potential evapotranspiration (P-PET). Here, in our data files, we re-label 'P-PET' as 'DEF' for 'deficit'. For both historical and future data the months correspond to a "fire year", or a year begining on October 1st and ending on September 30th. Due to this, data for the months of October, November, and December are the values recorded for previous year. For example, P-PET data for November 2002, is the estimate of P-PET for November 2001. 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) or the Scenarios Network for Alaska and Arctic Planning webpage. ---------------------------------------------------------------------- ----------------------- Resolution ----------------------------------- ---------------------------------------------------------------------- Spatial Resolution: 2 km Temporal Resolution: monthly Time Coverage: random 1950-2099 ---------------------------------------------------------------------- ------------------------ File Naming --------------------------------- ---------------------------------------------------------------------- --------------------- Historical Data -------------------------------- Example: tas_mean_C_cru_TS31_01_1950_FY.tif 'tas' - climate variable, tas = surface temp, DEF = P-PET '_mean_C' - units, mean_C = degree celsius, tot_mm = millimeters '_cru_TS31' - Based off of CRU TS climate data (http://www.cru.uea.ac.uk/cru/data/hrg/).
