Long name: Alaskan Layered Pollution and Chemical Analysis

Field dates: Jan - Feb 2022

Location: On the ground in Fairbanks, Alaska

Overarching goal: To address the following research questions: (1 What are the sources of INPs that facilitate formation of ice fog? (2 Is there an evolution in INP composition as the transition from clear to foggy conditions occurs? and (3 How do INPs modulate ice fog under given cooling scenarios?

Long name: ARCtic Study of Permafrost Ice Nucleation

Field dates: Sep 2021

Location: On the ground, ATV, and small boat near Utqiaġvik, Alaska

Overarching goal: To to address the following research questions: 1) What microbes are associated with the high levels of INPs in permafrost? 2)Are the INPs (and microbes) present in permafrost also found in lakes, rivers, coastal waters, and the ocean, and in air above these surfaces? and 3) Do these INPs have abundances and properties that might be expected to modulate cloud microphysics and radiative properties?

Long name: Cloud and Aerosol Interactions over the Southern Ocean

Field dates: May 2023 - May 2025

Location: On the Australian vessels, RV Investigator and RSV Nuyina, in the Southern Ocean south of Tasmania and at Davis Station, Antarctica

Overarching goal: To characterize the role of natural aerosol in modulating the properties of clouds and precipitation over the Southern Ocean region through Australian ship- and Antarctic-based measurement campaigns. 

Long name: Department of Energy Atmospheric Radiation Measurement (DOE ARM) Program INP mentor

Field dates: Aug 2020 to present

Location: On the ground and tethered balloon at multiple locations in the USA and Tasmania

Overarching goal: To provide a full, in-house service to help ARM obtain quality INP samples and data from multiple ARM observatory locations each year via routine ground-based and aerial sampling.

Long name: Multidisciplinary drifting Observatory for the Study of Arctic Climate

Field dates: Sep 2019 - Oct 2020

Location: On the German icebreaker Polarstern in the central Arctic Ocean

Overarching goal: To achieve unprecedented characterization of INP abundance and sources (including biological) to evaluate their capacity to modulate cloud ice formation over the central Arctic.

Long name: Antarctic Low Cloud Interaction with Natural Aerosol 

Field dates: Sep 2025 - Mar 2027

Location: At Palmer Station, on the Antarctic Peninsula

Overarching goal: To gain new insights into the influence of aerosol properties on cloud microphysics and the surface energy budget in coastal Antarctica. Due to the pandemic, this study was pushed back 2 year!
