VIIRS nighttime-light observation support and background sensitivity in Uzbekistan: frozen inputs and v13 reproducibility data

Frozen research inputs and offline v13 reproducibility outputs, with area-reconciliation extension v13.1, accompanying the manuscript Observation support and background sensitivity in VIIRS nighttime light change mapping in Uzbekistan. The archive contains a national 2020/2023 radiance and observation-support raster, 42 annual rasters (2012–2025) for three screened reference windows, ancillary sample references, daily radiance/geometry data for 192 fixed cells (140,352 cell-day rows), executable Python replay, pinned dependencies, CSV outputs, figures, checksums, a data dictionary and source acknowledgements. The v13.1 extension adds the original research-boundary snapshot, an executed Earth Engine control and an offline area audit. The original regional-weighted support is 436,025.802320 km²; using identical complete-cell integration at the same 2,727,284 cells gives 437,587.245413 km² in Earth Engine and 437,587.245386 km² in Python (27.3 m² difference). The original discrepancy is attributable to regional boundary/mask weighting. Previously reported local v13 scenarios are unchanged. The replay does not regenerate all earlier S1–S11 analyses or changing live portal products. Collection-1 geometry is joined to Collection-2 radiance by UTC date and grid centre; granule/orbit identity remains unverified. Independent nighttime field validation remains outstanding.
