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.

ILRC29 – International Laser Radar Conference (Hefei – China)

June, 24-28 2019

After 50 years, for the first time, the 29^th ILRC came to China! ILRC is held biennially under the oversight of the ICLAS, of the International Radiation Commission (IRC). The 29^th ILRC was co-hosted by six institutes/universities in China and supported by the Chinese Academy of Sciences and Hefei municipal government. It is also persistently supported by the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), and many international/national partners and enterprises.

During the 29^th ILRC, the new lidar technologies and techniques for profiling the aerosol and clouds, trace gases, water vapor, temperature, turbulence and 3D-wind were explored. The application of lidar networking and space-borne lidars were investigated. Emphasis was given to weather forecasting, environmental and climate change investigations combined with multiple instruments and platforms. The lidar technologies extended to ocean, land surface and biological applications were also present.

The 29^th ILRC was an excellent opportunity to share and exchange ideas. We would like to thank everyone who came at Cimel’s booth and poster presentation during ILRC29. We were pleased to welcome you all!

GPS reset

A GPS reset initially scheduled for April 6 has been postponed to November 2, 2019. We will update the software shortly so that your instruments are not affected by this modification. Stay tuned!
