An automated droplet freezing assay system to study ice formation activities of soil and biogenic particles at warm temperatures

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Nurun Nahar Lata

Ice nucleation (IN) efficiency of soil and biogenic particles at warmer temperatures (> -15° C) are least understood leading to poor representation of IN in models. We propose to build an…
