As highlighted by the success of the first two Conferences on Laser, Weather, and Climate in 2011 and 2013, ultra-short lasers launched into the atmosphere have emerged as a promising prospective tool for weath-er modulation and climate studies. Such prospects include lightning con-trol and laser-assisted condensation, as well as the striking similarities between the non-linear optical propagation and natural phenomena like rogue waves or climate bifurcations.

Although these new perspectives triggered an increasing interest and activity in many groups worldwide, the highly interdisciplinary nature of the subject limited its development, due to the need for enhanced contacts between laser and atmospheric physicists, chemists, electrical engineers, meteorologists, and climatologists.

Further strengthening this link is precisely the aim of the third Conference on Laser, Weather and Climate (LWC2015) at the World Meteorological Organisation (WMO) in Geneva, gathering the most prominent specialists on both sides for tutorial talks, free discussions as well as networking.

Let’s go on building together a new community dedicated to laser-based weather modulation.

We look forward to welcoming you in Geneva!
