HAMSTER: Hyperspectral Albedo Maps dataset with high Spatial and TEmporal Resolution

This dataset contains 365 hyperspectral albedo maps of Earth with a temporal resolution of 1 day. The hyperspectral albedo maps are built from a 10-year average of the MODIS Surface Reflectance dataset (MCD43D42-48, version 6.1). Using a Principal Component Analysis (PCA) regression algorithm we combine different hyperspectral laboratory and in-situ measurements datasets of various dry soils, vegetation surfaces and mixure of both to reconstruct the albedo maps in the entire wavelength range from 400 to 2500 nm. The hyperspectral albedo maps have a spatial resolution of 0.25° in latitude and longitude.

Additional hyperspectral albedo maps with a coarser spatial and spectral resolutions are available in the "Data sets" supplemetary material of "HAMSTER: Hyperspectral Albedo Maps dataset with high Spatial and TEmporal Resolution" (Roccetti et al., 2024, https://doi.org/10.5194/egusphere-2024-167) or upon request to the corresponding author.
