Malaysia starts cloud seeding to help clear toxic haze

Malaysia initiated a three-day cloud-seeding operation in Sarawak on Thursday to combat hazardous haze caused by Indonesian forest fires, which have significantly degraded air quality in the region. The operation targets three hydroelectric dams and 13 water catchment areas, aiming to both reduce pollutant concentrations and replenish water supplies as hotter, drier weather is anticipated.

Air quality in Sarawak deteriorated to hazardous levels, with peak readings exceeding 475, prompting state welfare agencies to distribute over 450,000 boxes of drinking water to over 225,000 residents since January. Cloud seeding, carried out using a C-130 aircraft releasing a saline solution at altitudes of 5,000 to 7,000 feet, relies on favorable cloud formations and atmospheric conditions for success.

Committee Chair Douglas Uggah Embas emphasized the importance of increasing water levels while the weather remains favorable. Seven locations recorded air quality levels above 300, with Serian registering an API of 475, classified as hazardous under national guidelines. The operation, involving the air force, the National Disaster Management Agency, and the Malaysian Meteorological Department, is ongoing, with continuous monitoring of cloud development and rainfall outcomes.
