Doppler Lidar Data Products Released for 3 ARM Campaigns
Time-height displays show Doppler lidar data from April 14, 2020, during the Cold-Air Outbreaks in the Marine Boundary Experiment (COMBLE). The top plot indicates wind speed (color) and wind vector direction (arrows), and the bottom plot provides vertical velocity. The Atmospheric Radiation Measurement (ARM) user facility operates Doppler lidars around the globe to provide measurements…

Storm Animations, CACTI-Style
New visualizations turn data into dramatic 3-dimensional images of evolving thunderstorms ARM’s main observatory for the 2018–2019 Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign was between two mountain ridgetops in Argentina. It included the second-generation C-Band Scanning ARM Precipitation Radar (CSAPR2), the bulb-like structure in the center. Its case-study data have been translated…
