This data set corresponds to the referenced work (, related to climate projections, for the Canary Islands, of some risk indicators derived from the Canadian Forest Fire Weather Index (FWI). Climate regionalized projections for the Canary Islands were performed, at 3 km spatial resolution, using as boundary conditions some of the results provided by the Coupled Model Intercomparison Project (CMIP5) initiative, and covering the recent past (1980–2009) and future (2070–2099) periods, under two Representative Concentration Pathways, 4.5 and 8.5. A dynamical downscaling technique has been applied, using the Weather and Research and Forecasting (WRF) model driven by the results of three CMIP5 models (GFDL-ESM2M, IPSL-CM5A-MR and MIROC-ESM). Each file, in netCDF format, has a name with the following nomenclature: where: * VAR is the variable (fot30, fwi, lofs) * PERIOD is the simulation period, and also indicates, for future periods, the corresponding emission scenario (1980_2009, 2070_2099_rcp45, 2070_2099_rcp85) *FREQ is the frequency for data: year (mean value for the annual values of the whole period) or monthly (mean value for each month, that is, the average for all the januaries in the period, …) * GCM is the global climate model (GCM) whose results have been used to drive the WRF simulations (GFDL_ESM2M, IPSL_CM5A_MR, MIROC_ESM) The three variables provided are: * fwi: monthly mean of daily values for the Canadian Forest Fire Weather Index (FWI). For this variable, results are also provided for a mid-century period (2030-2059). * fot30: percentage of days with an FWI greater than 30. This value is usually considered as an indicator of severe fire danger situations. * lofs: measures the extension in days of fire weather season. This starts/finishes each year when FWI exceeds/decreases the value 15 for more than two consecutive weeks. The provided values correspond to the average for each period analyzed.
