The abundance of ground-level atmospheric ice-nucleating particles and aerosol properties in the North Slope of Alaska ...
We present one of the first long-duration ambient ice-nucleating particle (INP) data for the Arctic, nearly 50 months of INP concentrations ( n INP ) measured continuously at the Barrow Atmospheric Baseline Observatory in North Slope of Alaska (BRW-NSA). The BRW-NSA site is located at 71.32° N, 156....

| Summary: | We present one of the first long-duration ambient ice-nucleating particle (INP) data for the Arctic, nearly 50 months of INP concentrations ( n INP ) measured continuously at the Barrow Atmospheric Baseline Observatory in North Slope of Alaska (BRW-NSA). The BRW-NSA site is located at 71.32° N, 156.61° W and about 6 km northeast of the nearest residential area, Utqiaġvik, AK. The field measurements were initiated in October 2021 and lasted until May 2024 as part of the multi-year remote observation campaign, called the Examining INP at NSA (ExINP-NSA; https://www.arm.gov/research/campaigns/nsa2021exinpnsa last seen on June 16th, 2024). A portable ice nucleation experiment chamber (PINE-03), which simulates adiabatic expansion cooling, was used to directly monitor the ground-level ambient INP abundance with an approximately 12-minute time resolution from October 2021 to December 2023. We report PINE-03-measured n INP data over a wide range of heterogeneous freezing temperatures from -16 °C to -31 °C. ... |
