The NASA Earth eXchange-Global Daily Downscaled Projections-Fire Weather Index (NEX-GDDP-FWI) INTRODUCTION: ----------------------------- The NASA Earth eXchange-Global Daily Downscaled Projections-Fire Weather Index (NEX-GDDP-FWI) is a dataset that provides global fire weather projections derived from daily Earth System Model (ESM) simulations. The dataset uses the Canadian Forest Fire Weather Index System (CFWIS) framework to estimate fire danger by considering the effects of fuel moisture and wind on fire behavior and spread. The dataset includes retrospective (1950-2014) and prospective (2015-2100) simulations from 33 ESMs participating in the Coupled Model Intercomparison Project Phase 6 (CMIP6) under four Shared Socio-economic Pathways (SSPs). To make the dataset more accessible, the fire weather metrics are summarized at coarser temporal scales (monthly and annually), and source codes are provided for investigating daily fire weather. Additionally, Multi-Model Ensemble (MME) datasets are provided for each fire weather metric, which include monthly and annually summarized fire weather metrics. The total data volume of the dataset is approximately 5.1 TB and is available through the NASA Advanced Supercomputing (NAS) Data Portal. This publicly available dataset has the potential to be broadly used in not only for wildfire risk assessment but also for various future climate change impact assessments and preparedness. DIRECTORY & FILE NAMING CONVENTIONS & STRUCTURE ------------------------------------------------ The data directory and file naming convention is the following: //__fwi_metrics__.nc The "parts" are defined as: := folders for summarized temporal resolution (i.e., monthly or yearly) := folders for individual model or multi-model ensemble := name of individual model or multi-model ensemble percentile (i.e., MME25,50, and 75). := shared socio-economic pathways (i.e., historical, ssp126, ssp245, ssp370, and ssp585). := summarized temporal resolution (i.e., monthly or yearly). := The year of the fire weather data Here is an example file: "Yearly/MME/MME50_ssp245_fwi_metrics_yearly_2023.nc" - Yearly : folder for summarized temporal resolution - MME : folder for individual model or multi-model ensemble - MME50 : 50th percentile of multi-model ensemble - ssp245 : ssp scenario - yearly : summarized temporal resolution - 2023 : the year of fire weather data All files are in NetCDF file format.
