In January, CERTAINTY researchers delivered inspiring lectures to ERCA students, covering topics like aerosols and clouds, atmospheric dynamics, weather systems, remote sensing, and statistical analysis. Welcome to the new generation of scientists!

Currently, our poster session is in full swing at the CERTAINTY Annual Meeting in Grenoble! It’s an exciting moment to connect and share insights with our amazing team. The energy and collaboration are truly inspiring! ✨

Kicking off a productive CERTAINTY meeting! We are planning for Year 2 and beyond, aligning on current progress & strengthening collaborations with our partners & International advisory committee. Exciting coordinated modeling case studies ahead. Welcome to all new team members!

Fruitful Aerosol-Cloud Cluster Session today! We assessed progress, explored new synergies, and discussed future collaborations. 🙏 A big thank you to all our speakers and participants for their valuable contributions! Stay tuned for upcoming joint activities.
