Doppler spectra from ARM Doppler Lidar during ARMing the Edge

Overview:

There is a need for long-term observations of cloud and precipitation fall speeds in validating and improving rainfall forecasts from climate models. To this end, the U.S. Department of Energy Atmospheric Radiation Measurement (ARM) user facility Southern Great Plains (SGP) site at Lamont, Oklahoma, hosts five ARM Doppler lidars that can measure cloud and aerosol properties. In particular, the ARM Doppler lidars record Doppler spectra that contain information about the fall speeds of cloud and precipitation particles. In this dataset, we provide the Doppler spectra from the ARM Doppler lidar at C1 recorded in April 2022 during ARMing the Edge.

Abstract:

Purpose:

The purpose of this data are to show the vertical velocities of aerosol particles, cloud particles, and raindrops in the boundary layer. Such information is used to learn more about turbulence, vertical aerosol transport, and precipitation processes in the boundary layer.

Data Usage:

The data should be used to look at the vertical motions of particles above SGP C1. This will provide information about turbulence, cloud bases, and precipitation in the boundary layer.
