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

This dataset contains 365 hyperspectral albedo maps of Earth, one for each day of the year. The hyperspectral albedo maps are built from a 10-year average of the MODIS Surface Reflectance dataset (MCD43D 42-48, version 6.1). Using a Principal Component Analysis (PCA) regression algorithm we combine different hyperspectral laboratory and in-situ measurements spectra 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, with a spectral resolution of 10 nm. The hyperspectral albedo maps have a spatial resolution of 0.05° in latitude and longitude. Additional hyperspectral albedo maps with a coarser spatial or spectral resolution are available upon request.
