Microphysical observations of precipitating particles are crucial for numerical weather prediction models and remote sensing retrieval algorithms. This dataset provides a unified, comprehensive collection of particle microphysical observations from the Precipitation Imaging Package (PIP) over the Northern Hemisphere. Data spans from 2014-2023 across 10 measurement sites and encompasses over 775 thousand precipitating minutes. Within this dataset, users will find a range of microphysical attributes for rain and snow, along with higher-order products.
