Ultra-High-Resolution Lidar Reveals Hidden Cloud Structures

A man explains to a group of scientists the functions and capabilities of the machinery behind him, which includes a blue metal ladder and a large computer monitor displaying bright green waves of water particles.

Scientists at Brookhaven National Laboratory and collaborators — most of them alumni, faculty, staff and current students from Michigan Tech — have developed a new type of lidar that can observe cloud structures at the scale of a single centimeter. In the University’s Pi Cloud Chamber, they used it to directly observe fine cloud structures in the uppermost portion of laboratory-generated clouds.

The team’s results, published in the Proceedings of the National Academy of Sciences, provide some of the first experimental data showing how cloud droplet properties near the tops of clouds differ from those in the cloud interior. These differences are crucial to understanding how clouds evolve, form precipitation and affect Earth’s energy balance.

“This lidar is essentially a microscope for clouds,” said Fan Yang ’17 (Ph.D. in Atmospheric Sciences), an atmospheric scientist at Brookhaven and the lead author of the study. “Because we designed the lidar ourselves, we were able to optimize everything — from the laser system to the timing electronics — to achieve the centimeter-scale resolution needed to study cloud physics in a totally new way.”

In this guest blog, Karen McNulty Walsh of Brookhaven explains how the team developed an innovative, centimeter-scale view into lab-created clouds to uncover structural features important to rainfall, brightness, and representation in atmospheric models.
