SMOLDER: 8-day slow-predictor cube and auxiliary rasters for Australia (2015–2020)

Companion data for the SMOLDER wildfire-risk model (https://github.com/catKorb/smolder-wildfire-australia). cube_slow_8day.zarr: leaf area index, soil moisture and precipitation in 8-day bins on a fixed 2015–2020 day axis (means for LAI and soil moisture, sums for precipitation), same grid as the daily cube. Read by the model's 144-day slow branch. aux_rasters/: slope and aspect (ETOPO1), lightning climatology (LIS/OTD) and cached BARRA2 wind fields. The released model does not use them; they are included for extensions. Use together with the 2020 daily cube (10.5281/zenodo.22115979).
