In October 2024, leading scientists and researchers gathered for the Workshop on Air Quality in the Eastern Mediterranean (3–4 October 2024), a scientific event dedicated to the memory of Ioannis Ziomas — a respected colleague, mentor, and pioneer in atmospheric chemistry.

The workshop marked the 30th anniversary of the MEDCAPHOT-TRACE campaign, one of the most influential coordinated research efforts ever conducted in the Mediterranean region on photochemical air pollution.

The workshop served not only as a scientific forum, but also as a collective reflection on Prof. Ziomas’ long-lasting contribution to atmospheric science and European research collaboration.

A LIFE SIRIUS–Driven Scientific Initiative

As part of its broader dissemination and scientific engagement activities, LIFE SIRIUS supported and integrated this workshop as an extra thematic action, extending the project’s impact beyond its core technical outputs.

By embedding the event within LIFE SIRIUS, the workshop:

• Created a bridge between historical landmark research and contemporary air-quality challenges
• Fostered dialogue between senior scientists, early-career researchers, and policy-relevant experts
• Strengthened the scientific legacy that underpins today’s air-quality forecasting and early-warning systems

This alignment highlights LIFE SIRIUS not only as a project delivering operational tools, but also as a platform for scientific continuity and community building.

Relevance for Today’s Air-Quality Challenges

Three decades later, the scientific questions addressed by MEDCAPHOT-TRACE remain highly relevant. Climate change, rising temperatures, and persistent urban emissions are intensifying ozone episodes and air-quality extremes across the Mediterranean basin.

Workshops like this anniversary event highlight:

• The continuity of scientific knowledge across generations
• The importance of long-term observational data
• The need for integrated approaches combining atmospheric chemistry, meteorology, and policy

These principles are closely aligned with the mission of LIFE SIRIUS, which builds on decades of scientific progress to support evidence-based air-quality management, early warning systems, and climate-resilient cities.

Looking Forward, Building on a Strong Foundation

By revisiting MEDCAPHOT-TRACE at its 30-year milestone, the workshop reaffirmed the value of collaborative European science and honoured a legacy that continues to shape modern air-quality research.

Professor Ioannis Ziomas’ vision — rigorous science in service of society — remains a guiding reference for current and future initiatives addressing air pollution and climate risks in the Eastern Mediterranean.
