Description: Access and analyze multi-band greenspace seasonality data
        cubes (available for 1,028 major global cities), global
        Normalized Difference Vegetation Index / land cover data from
        the European Space Agency WorldCover 10m Dataset, and
        Sentinel-2-l2a images. Users can download data using bounding
        boxes, city names, and filter by year or seasonal time window.
        The package also supports calculating human exposure to
        greenspace using a population-weighted greenspace exposure
        model introduced by Chen et al. (2022)
        <doi:10.1038/s41467-022-32258-4> based on Global Human
        Settlement Layer population data, and calculating a set of
        greenspace morphology metrics at patch and landscape levels.
