Jakarta, Oct. 19 -- Indonesia's National Research and Innovation Agency (BRIN) is supporting scientific evaluations of efforts to combat wildfire haze through weather-modification operations using dry ice.

Florentinus Heru Widodo, a principal engineer at BRIN's Research Center for Limnology and Water Resources, said here Monday that an integrated team was testing dry ice, or solid carbon dioxide.

Unlike cloud seeding, which aims to increase the chance of rain from suitable clouds, dry ice is being tested to determine whether it can alter temperatures in an atmospheric inversion layer.

"Dry ice has a temperature of about minus 78.5 degrees Celsius. When released into the atmosphere, it sublimates, changing from a solid to a gas while ab...
