    On June 17, 2022, the Moderate Resolution Imaging Spectroradiometer
    (MODIS) on board NASA’s Aqua satellite acquired a true-color image of
    multiple red hot spots scattered across the northern section of
    Northern Territory, Australia.

    Each hot spot marks an area that the thermal bands on the instrument
    detected high temperatures. When combined with typical smoke, as in
    this image, such hot spots mark actively burning fire. While it’s not
    possible to determine the cause of a fire from satellite imagery, given
    the time of year and widespread nature of the fires, it’s a good bet
    that most of these are prescribed burns. Prescribed burns are
    deliberately planned, ignited, and managed in a particular area in the
    landscape, with the goat to reduce fine fuel hazards, manage native
    vegetation, and protect biodiversity in strategic areas, such as parks
    and reserves.

    On June 10, the Northern Territory Police, Fire and Emergency Services
    published a media release explaining that “the 2022 Top End fire season
    is fast approaching, with extensive mitigation burning underway across
    the Northern Territory’s Top End to reduce bushfire risk”. Bushfires
    can occur at any time in Australia, but the peak season in northern
    Australia is in the dry season, which is winter and spring (June
    through November).
