| Abstract | The authors describe experiments with emissions from real trees in a photochemical reaction chamber. Focus was put on SOA formation and characterization of the gaseous precursors and oxidation products by GC-MS, PTR-MS and a CIR-TOF-MS. Experiments were conducted with and without ammonium sulfate seeds. The authors contrast a monoterpene (& other BVOC) emitter, birch, with tropic trees fig and palm, which are isoprene emitter. The birch serves also to test the current results against previous experiments. As expected SOA mass from isoprene emitters is small and was only achieved in seeded experiments. The isoprene SOA yields are a high while the MT yields are in the ball park of previous experiments. The authors show indirectly that the relative large yields for the isoprene emitter likely arise from other BVOC, partly below the detection limits. The study was well conceptual well designed and the manuscript presents new material, especially about emissions from tropical tree species and their oxidation products as well as their SOA formation potential. The manuscript is well written. It should be published in ACP after the authors addressed the following major and minor points. |
