Indonesia Adapts 1940s Dry-Ice Technology in Fight to Clear Haze

Indonesia is repurposing a weather-modification technique dating back to the 1940s to help clear thick haze blamed on forest fires. Authorities plan to concentrate efforts in areas upwind of airports, where improved visibility could allow water-bombing and cloud-seeding aircraft to resume operations. The approach borrows from methods originally developed nearly a century ago, now adapted to Indonesia’s current air-quality emergency. The report frames the effort as a renewed attempt to manage visibility constraints that can disrupt aviation activity during periods of severe pollution. Details on timing and specific sites were not provided in the excerpt.
