NOAA Soundings IMPACTS

The NOAA Soundings IMPACTS dataset was collected from January 1, 2020, through March 1, 2023, during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. The goal of IMPACTS was to provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution, examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands, and improve snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. These radiosonde data files include wind direction, dew point temperature, geopotential height, mixing ratio, atmospheric pressure, relative humidity, wind speed, temperature, potential temperature, equivalent potential temperature, and virtual potential temperature measurements at various levels of the troposphere. The data are available in netCDF-4 format.

NOAA声学测风仪观测的IMPACTS数据集，收集自2020年1月1日至2023年3月1日，期间进行的针对大西洋沿岸威胁性暴风雪的微物理和降水调查（IMPACTS）野外考察。IMPACTS项目旨在提供对雪带形成、组织和发展机制至关重要的观测数据，探讨雪粒的微物理特性及其可能增长机制在雪带中的变化情况，并提升降雪遥感解释和建模能力，以显著推进预测能力。这些无线电探空数据文件包含了风向、露点温度、位势高度、混合比、大气压力、相对湿度、风速、温度、位温、相当位温和虚位温等测量值，在平流层不同层次上均有记录。数据以netCDF-4格式提供。
