Advanced Microwave Precipitation Radiometer (AMPR) IMPACTS

The Advanced Microwave Precipitation Radiometer (AMPR) IMPACTS dataset consists of brightness temperature measurements collected by the Advanced Microwave Precipitation Radiometer (AMPR) onboard the NASA ER-2 high-altitude research aircraft. AMPR provides multi-frequency microwave imagery, with high spatial and temporal resolution for deriving cloud, precipitation, water vapor, and surface properties. These measurements were taken during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) campaign. Funded by NASA’s Earth Venture program, IMPACTS is the first comprehensive study of East Coast snowstorms in 30 years. Data files are available from January 18, 2020, through March 2, 2023, in netCDF-4 format.

高精度微波降水辐射计（Advanced Microwave Precipitation Radiometer，简称AMPR）的IMPACTS数据集包含由NASA ER-2高空研究机载AMPR收集的亮度温度测量值。AMPR提供多频微波图像，具有高空间和时间分辨率，可用于推导云、降水、水汽和地表特性。这些测量值是在针对大西洋沿岸威胁性暴风雪（Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms，简称IMPACTS）的活动中进行的。由NASA地球探险计划资助的IMPACTS是对东海岸暴风雪进行的30年来首次全面研究。数据文件以netCDF-4格式，从2020年1月18日至2023年3月2日均可获取。
