Junwen’s paper ‘Isotope constraints of the strong influence of biomass burning to climate-forcing Black Carbon aerosols over Southeast Asia’ was published in STOTEN. This is our first paper on monitoring biomass burning in Bachok background station of Malaysia. We are greatly in debt to Professor Pauzi and Chui Wei of University of Malaya with whom we have developed long-term collaboration and personal friendship. And I hope more to come with our collaborations. Congratulations to Junwen as well!
