May 2025

As part of the official visit of French President Emmanuel Macron to Southeast Asia in May 2025, a delegation of French companies and institutions took part in a strategic mission in Vietnam and Indonesia under the “France-Vietnam: A Shared Future” initiative.

CIMEL, represented by Idris SANHAJ, our Sales and Marketing Director, was honored to be part of the French delegation, reaffirming our commitment to international scientific and environmental cooperation.

During this mission, CIMEL had the opportunity to engage with several national authorities and scientific institutions:

  • In Indonesia, Idris visited the BMKG (Badan Meteorologi, Klimatologi, dan Geofisika), the national agency for meteorology, climatology, and geophysics, to explore avenues for collaboration on atmospheric observation and extreme weather monitoring (picture on the left).
  • In Vietnam, he met with the Vietnam Academy of Science and Technology (VAST) and several research teams to discuss cooperation in aerosol monitoring, dust events, and solar radiation measurements (picture on the right).

This mission, supported by Team France Export and the French Embassy, highlighted CIMEL’s role as a key player in atmospheric observation technologies in the Asia-Pacific region — particularly in the context of the Just Energy Transition Partnership (JETP) and climate change adaptation strategies.

We are deeply grateful to all our partners for their warm welcome and shared ambition to tackle pressing environmental challenges through science and innovation.

CIMEL is proud to contribute to global initiatives for a cleaner, more resilient, and sustainable future.

COBIACC campaign

COBIACC campaign

Is the rural atmosphere better than elsewhere?

For the entire month of July in Caillouël-Crépigny (France), scientists from the University of Lille and ATMO Hauts-de-France will analyze particles in the air and their impact on health in rural areas.

Since 28 June, more than twenty air pollution measuring devices deployed over 100 m² in the commune of Caillouël-Crépigny (02) may answer this question.

Objectives: To understand the formation and the composition of particles and their precursors in the air in a rural environment during the summer period.

The sensors collect dust from the countryside and nearby dust from forests, roads, buildings and industries in the distance.

The facility consists of four containers installed on 100 m² in the village square of Caillouël-Crépigny. They accommodate twenty-two observation instruments including our Cimel Sun Sky Lunar CE318-T photometer as well as our CE376 micro-LiDAR. These instruments, unique in France, measure the impact of climate change on air quality, biodiversity and health. Thirty researchers take turns night and day to study the chemical modifications of particles during periods of high heat.

This campaign was named COBIACC for Campagne d’OBservation Intensive des Aérosols et précurseurs à Caillouël-Crépigny. It is the result of a partnership between Labex CaPPA, a laboratory of excellence in Lille, CPER Climibio, an environmental project involving 16 laboratories in the Hauts-de-France and Atmo Hauts-de-France, the regional air quality observatory.
