AdaptationAtlas/hazards: v0.1.0 - NEX-GDDP 2025

Release: Adaptation Atlas Hazards – Delta Method This release provides the code used to generate the Adaptation Atlas climate hazards dataset using the NASA NEX-GDDP CMIP6 projections. Dataset overview Spatial resolution: 0.25° Temporal coverage: 2021–2100, aggregated into four periods (2021–2040, 2041–2060, 2061–2080, 2081–2100) Scenarios: SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5 Global Climate Models: ACCESS-CM2, ACCESS-ESM1-5 CMCC-ESM2 CanESM5 EC-Earth3 EC-Earth3-Veg-LR GFDL-ESM4 INM-CM4-8 INM-CM5-0 IPSL-CM6A-LR KACE-1-0-G MIROC6 MPI-ESM1-2-HR MPI-ESM1-2-LR MRI-ESM2-0 NorESM2-LM NorESM2-MM, TaiESM1 Includes individual GCM outputs and the multi-model ensemble mean Daily variables used: minimum and maximum temperature, precipitation, solar radiation, and relative humidity (r1i1p1f1 ensemble member) Hazard indices included Drought stress NDD – Number of dry days NDWS – Number of soil moisture stress days TAI – Thornthwaite's aridity index Heat stress NTx35 – Crop heat stress days (Tmax > 35 °C) NTx40 – Extreme crop heat stress days (Tmax > 40 °C) HSM_NTx35 – Heat stress days for maize during the growing season HSH – Human heat stress index THI – Cattle thermal humidity index Waterlogging and flooding NDWL0 – Days with soil waterlogging at saturation or above NDWL50 – Days with soil waterlogging between field capacity and saturation Notes Future daily climate data are generated by applying monthly deltas to historical observations, preserving observed daily variability. Additional QA/QC checks were applied to ensure consistency across delta, monthly, and daily products. Data are available internally on the EiA server and via Atlas STAC catalog and AWS S3 bucket
