Global Surface Blue-sky Albedo Climatology Dataset from 20-year MODIS Products (500m)

Surface albedo plays a critical role in climate, hydrological, and biogeochemical modeling and weather forecasting. Therefore, precisely mapping surface albedo climatology globally is necessary to better parameterize environmental systems. We generated a new global surface blue-sky actual and snow-free albedo climatology dataset from 20-year MODIS products from the Google Earth Engine (GEE). The 500m global surface blue-sky daily albedo climatology dataset follows the basic MODIS product format and employed the sinusoidal projection. It includes historical and snow-free blue-sky albedo climatology data. Only the first days of each 8-day in a year were uploaded to Zenodo due to the data storage limitation, and the full dataset is available at http://glass.umd.edu/albedo_clim/. For application convenience, the land cover climatology of MODIS product (MCD12Q1) is also generated and attached. The International Geosphere-Biosphere Programme (IGBP) and PFT classification climatology of MCD12Q1 since 2001 were also generated.The full dataset (365 days) is freely available at http://glass.umd.edu/albedo_clim/. The surface albedo climatology of CMG format (0.05° and 0.5 °) are published separately at (https://doi.org/10.5281/zenodo.5044125), and the corresponding paper is being submitted to Earth System Science Data (ESSD)
