Observations

Pure-I/O data loader for MTBS (Monitoring Trends in Burn Severity) post-fire burn-severity products. Provides the time-invariant final burn-severity raster for a single fire: a thematic severity class layer (1=unburned/low … 6=non-processing-area mask) and the continuous dNBR (differenced Normalized Burn Ratio) layer, on the native Albers/geographic raster the MTBS product ships. Sourced as GeoTIFF bands of the per-fire MTBS bundle (one final product per fire — there is no temporal progression).

Pure-I/O data loader for NIFC / GeoMAC daily wildfire perimeters, RASTERIZED OFFLINE to a burned-fraction grid. Provides a daily burned_fraction(lon,lat) field in [0,1] — the per-cell fraction of area inside the cumulative (or daily) fire perimeter — read as an ordinary gridded time series (one NetCDF per day). This is the day-by-day fire PROGRESSION reference for fire-model validation (campfire-e2e Phase E1/E2).

OpenAQ regridding model — the coupler half of the openaq loader+regridding-model split (RFC pure-io-data-loaders §6/§7; bead esm-3nc.5). Exposes ground-based air quality monitoring observations (PM2.5, PM10, O3, NO2, SO2, CO, BC, PM1, NO, NOx) on the simulation's target grid for coupling into EarthSciML systems.

Pure-I/O data loader for NASA FIRMS VIIRS active-fire detections. Provides per-overpass point detections (one row per fire pixel per satellite pass): fire radiative power, brightness temperature, and detection confidence at irregular (lon,lat) detection locations resolved at runtime. This is the SUB-DAILY fire-front timing reference for fire-model validation (campfire-e2e Phase E1/E2) — the best progression signal between daily perimeters.
