    A shroud of haze stretched along the Indo-Gangetic Plain, stretching
    from Pakistan in the west to reach Bangladesh in the east in late
    October 2022.

    The Moderate Resolution Imaging Spectroradiometer (MODIS) on board
    NASA’s Aqua satellite acquired a true-color image of about half of the
    gray cloud of aerosols on October 26. The gray haze becomes thickest
    over Utter Pradesh, where it obscures the land beneath from view.

    Clusters of red hot spots, each representing actively burning fire, sit
    in northeastern Pakistan and northwest India. They are thickest in the
    Indian states of Punjab and Haryana, where rice and wheat are widely
    grown. These are primarily agricultural fires, primarily used to clear
    stubble from fields after harvest. Crop burning typically peaks during
    the first week of November a time that often coincides with falling
    temperatures and slow wind speeds, meteorological conditions that can
    lead to temperature inversions, which trap smoke in place.

    The fires release several types of gases into the atmosphere, including
    smog-forming carbon monoxide and nitrogen dioxide. They also release
    aerosols, such as black carbon and organic carbon, that contribute to
    elevated levels of PM2.5, which can cause health problems.

    While agricultural burning contributes heavily to the aerosol pollution
    and haze over the Indo-Gangetic Plain, it is not the only factor.
    Industry, coal burning for heat, and automobile emissions also heavily
    contribute to aerosol pollution in the region.
