    Greening in Nigeria

    The rainy season in northern Nigeria runs from mid-May to September,
    bringing much-needed water to the otherwise dry savannah grasslands and
    filling local rivers. While southern Nigeria enjoys a longer and wetter
    rainy season, the more moderate precipitation in the north means that
    this is the season of planting the crops that will be harvested during
    the dry season.

    The Moderate Resolution Imaging Spectroradiometer (MODIS) on board
    NASA’s Terra satellite acquired a true-color image of northwestern
    Nigeria on October 22, 2021, a few weeks after the end of the rainy
    season. The entire region is painted with a wash of green, particularly
    next to the Nile River (west) and in the south, where precipitation was
    highest.

    While this single image allows a view of post-rain greening, to see the
    change in landcover over time it is ideal to compare two different
    images. Thanks to the NASA Worldview app, a roll-over comparison
    between two Aqua MODIS images, one acquired on May 24 and the image
    acquired on October 22, can be viewed here.
