Lakes Environmental Software has announced the acquisition of the CALPUFF atmospheric dispersion modelling system from Exponent. This transaction, confirmed on 5 May 2024, marks another step in the evolution of CALPUFF, a model widely used by researchers, environmental consultants, and regulatory agencies globally.

    CALPUFF is a US EPA Guideline model for all applications > 50km, it is also the guideline model for all near-field applications where the steady state assumption does not apply, i.e., complex terrain and complex meteorological environments (Sea breeze, boundary layers, etc.). In addition, it is a model widely used in odour modelling. The code of this model, while being publicized as "freely available," is not open source, as far as we know. Over the years, the ownership of the code has changed from SRC to TRC, Earth Tech, Exponent, and now Weblakes.

   The next 8th World Congress of the Digital Olfaction Society will take place on December 5-6, 2024 at Ap Tokyo Yaesu in Tokyo, Japan. The Digital Olfaction Society (DOS) hosts events approximately every two years. The first DOS event took place in Berlin, Germany and since then, five more events have taken place, predominantly in Tokyo, Japan.

  The previous edition, the 7th Digital Olfaction Society World Congress, took place on November 29-30, 2022 in Tokyo - Japan, in-person & online. The objective of DOS is to gather, share, and complete the knowledge recently established about olfactory digitization.
