Short summary

We present water uptake properties of haze particles originating from Indonesian peatland fires and further link the water uptake to particle chemical characteristics. Organic-rich wildfire haze particles are highly hygroscopic, governed by sulfate and promoted by secondary organic aerosol formation. Water-soluble organic fraction plays a minor role in determining particle hygroscopicity. This deepens our understanding, and reported results can be further applied into climate models.
