Haze was once an annual event in Singapore until 2019. In June 2023, experts warned of a high chance of its return later in the year due to climate factors.
Published on October 7, when Singapore’s PSI reached unhealthy levels for the first time since 2019, this interactive piece explains why the haze has returned after three years and it might differ this time.
The project includes data-driven insights, maps, and utilises new tools like VAPOR, a 3D visualisation tool for atmospheric data, to illustrate how smoke from Indonesian peatlands is transported to Singapore, contributing to the haze phenomenon.
