Wildfire time-of-arrival dataset and method code: variance-weighted kriging of satellite active-fire detections, evaluated in the United States and applied to South Korea

Companion data and code for the article published in Remote Sensing 2026, 18(19), 3321 (https://doi.org/10.3390/rs18193321). Derived 375 m time-of-arrival and ordinary-kriging standard-deviation rasters for 15 South Korean wildfires (EPSG:5179) and 29 western U.S. evaluation fires (EPSG:5070), produced by empirical variance-weighted kriging of polar-orbiting (VIIRS) and geostationary (GOES, Himawari) active-fire detections; the result statistics behind the tables and figures (per-survey and per-event Sorensen coefficient, five-configuration spatial block cross-validation with the variogram refitted per fold, variance-inflation sensitivity, and the status of all 21 Korean fires); and the code that implements the method. Derived products only; raw satellite inputs follow the original providers' terms.
