A Closer Look: Can cloud seeding help reduce pollution in Pakistan?

A Closer Look is The National's show where we take an in-depth look at one of the main stories of the week.

The UAE has helped the Pakistani city of Lahore with cloud-seeding flights to help fight against pollution.

The UAE is a pioneer in the weather modification technique having carried out thousands of flights over the years in the drive to encourage rainfall.

But how does firing salt flares into clouds help reduce harmful particles in the air?

Here, host Sarah Forster speaks to journalist Sarwat Nasir about how cloud seeding can help to combat pollution.

Hygroscopic salt flares are attached to an aircraft during a cloud-seeding flight between Al Ain and Al Hayer. At 9,000 feet above sea level, the plane releases the flares into the most promising white clouds, hoping to trigger rainfall.

Scientists in Abu Dhabi combine shooting the flares with releasing salt nanoparticles, a newer technology, into the clouds to stimulate and accelerate the condensation process and hopefully produce droplets big enough to then fall as rain.
