Short summary
Source profiles that allow peat fire contributions to be distinguished from other source contributions using receptor models are lacking for a wide variety of peat fuels and burning conditions. These profiles change with photochemical aging during transport. Fresh and aged profiles for a variety of peat fuels are measured with an oxidation flow reactor to improve source attributions at distant receptors.
