    From Space to Streets: NASA Tracks Pollution Sources in Real Time

    In Short এক নজরে

    NASA now tracks air pollution sources in real time using its TEMPO instrument on a satellite far above North America. It scans the region every hour in daylight, spotting tiny pollution spots from cities, highways, and factories down to neighborhood level. 

    Local planners and health agencies can use these maps to cut pollution and protect people living in heavily affected areas.
