Doppler spectra from ARM Doppler Lidar during ARMing the Edge

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.

为验证并优化气候模型的降雨预报结果，长期观测云和降水粒子的下落速度已成为一项必要的研究需求。为此，美国能源部大气辐射测量（Atmospheric Radiation Measurement, ARM）用户设施设于俄克拉荷马州拉蒙特的南部大平原（Southern Great Plains, SGP）站点，该站点配备了五台可测量云和气溶胶特性的ARM多普勒激光雷达。尤为重要的是，ARM多普勒激光雷达可记录多普勒光谱（Doppler spectra），其中包含了云和降水粒子下落速度的相关信息。本数据集提供了2022年4月在"ARMing the Edge"项目期间，C1站点ARM多普勒激光雷达所采集的多普勒光谱数据。
