Heard Island Glacier Albedo Dataset from VIIRS (2012–2024)

White-sky glacier albedo for Heard Island (53°06′S, 73°31′E), derived from NASA VIIRS VNP43 BRDF/albedo parameters for January 2012 to May 2024. Provides a glacier-wide area-mean albedo time series (4,466 valid daily broadband white-sky albedo records; mean 0.343 ± 0.062; range 0.037–0.723) and annual albedo rasters (2012–2024, GeoTIFF), with the ERA5-Land daily climate and SRTM elevation inputs and the GLIMS glacier outline used in the analysis. Temporal availability ≈ 98.9 % of study-period days; spatial coverage 44.04 % of glacier area (cloud-limited). Analysis code (Google Earth Engine + R) and per-file column definitions (DATA_DICTIONARY.md) are included. Data licensed CC BY 4.0; code under MIT.
