International DOAS Workshop 2025

Dear colleagues,

It was a great pleasure to host the International DOAS Workshop (DOAS 2025) from 9-11 July 2025 in Thessaloniki, Greece, at the Research Dissemination Center of Aristotle University of Thessaloniki (AUTh). The workshop provided a comprehensive international forum for presenting and discussing recent achievements in Differential Optical Absorption Spectroscopy research and applications, including the enhancement and development of instruments and inversion algorithms. We welcomed 75 on-site and 30 remote participants, who attended 46 oral and 27 poster presentations on the following topics:
  • DOAS applications
  • DOAS instrumentation and technological developments
  • Advancements in spectroscopy
  • Advancements in DOAS spectral retrievals
  • Advancements in radiative transfer theory and implementation
  • Advancements in inversion algorithm development and implementation for trace gases and aerosols
  • Advancements in DOAS satellite retrievals
  • Network development and harmonization across DOAS observations
  • Validation and data-assimilation applications with DOAS observations
Looking forward to welcoming you in Thessaloniki. On behalf of the Organizing Committee,

Alkiviadis Bais, Professor Emeritus
