Monitoring of atmospheric ice nucleating particle (INP) number concentrations on Tokyo Skytree

This repository includes the dataset for atmospheric ice nucleating particles (INPs) measued at a monitoring site located on the 458-m level floor of Tokyo Skytree in Sumida, Tokyo, Japan. The number concentrations of atmospheric INPs active in the immersion mode (i.e., under conditions relevant for mixed-phase cloud formation) have been quantified by analyzing the ice nucleating ability of ambient aerosol samples collected at this site using the Cryogenic Refrigerator Applied to Freezing Test (CRAFT) system. The INP number concentrations have been measured continuously and sequentially since 1 August 2016.
