Dr. Teppei J. Yasunari is Assistant Professor and Distinghished Researcher at the Arctic Research Center in Hokkaido University. He obtained his Bachelor degree in Science and Technology at Faculty of Science and Technology, Hirosaki University, Master degree in Geoscience at Graduate School of Environmental Earth Science, Hokkaido University, and PhD in Earth System Science, Graduate School of Environmental Science, Hokkaido University, in Japan, respectively.
He is also an athlete of powerlifting (powerlifter) in the 74-kg class (Masters 1: M1) as a team member of the Gym in Sapporo, Burst Limit, affiliating with Hokkaido Association in the Japan Powerlifting Association (JPA). (His official powerlifting records in 2023: "the recodrs at the Hokkaido competition: total 400 kg; squat: 140 kg; bench press: 100 kg; deadlift: 160 kg"; "the records at the national competition, Nippon Grand Prix: total 410 kg; squat: 135 kg; bench press: 100 kg; deadlift: 175 kg"; powerlifting records in 2024: "the recodrs at the Hokkaido competition: total 432.5 kg; squat: 152.5 kg; bench press: 100 kg; deadlift: 180 kg"; "Nippon Grand Prix (M1&74-kg class: 10th place; total 440 kg) & All Japan Teachers and Staffs Powerlifting Competition (74-kg class: 4th place; total 440 kg): Squat: 155 kg; Bench Press: 102.5 kg; Deadlift 182.5 kg").
His research activities were recently summarized and introduced in Hokkaido University's PR magazine (Literae Populi, p.20–21; also available in the Research Highlight). Also, he was recently appeared on a Japanese TV program by NHK WORLD ("Digital Eye: Disappearing Forests"), taking about wildfires and their air pollutions, etc. Please see here for a summary of the research content published in the “Research Profiles” for companies and government agencies.
His expertise is in the field of atmospheric aerosols, snow and ice, and environmental and climate sciences, and these interdisciplinary science field. Especially, his recent interests are light-absorbing aerosols such as dust, black carbon, and organic carbon, and their impacts on air pollution, climate, and interactions with snow and environment. He had worked at NASA Goddard Space Flight Center (GSFC) in Maryland, USA, under two different affiliations (GEST/UMBC and GESTAR/USRA) for more than 6 years during May 2009 and June 2015. During that moment, he developed so-called the GOddard SnoW Impurity Module (GOSWIM) for NASA’s global model, GEOS-5, which can simulate the snow-darkening effect by those light-absorbing aerosol depositions to snow (e.g., Yasunari et al., 2015, J. Geophys. Res. Atmos.; Lau et al., 2018, J. Geophys. Res. Atmos.). Based on his expertise, he contributed to write review papers on snow-darkening (Qian et al., 2015, Adv. Atmos. Sci.) and a part of Chapter 2 (High Mounrain Areas) of the recent IPCC Special Report on the Ocean and Cryosphere in a Changing Climate (IPCC SROCC) as one of the Contributing Authors (Hock et al., 2019, IPCC SROCC). After, he joined the current position at Hokkaido University, he has been working for wildfires over East Eurasia, and their causes and impacts on air quality such as PM2.5 (e.g., Yasunari et ai., 2018, Sci. Rep.), and other air pollutions (aerosols) such as Asian dust, Kosa (Yasunari et al., 2017, SOLA). Yasunari et al. (2021, Environ. Res. Lett.; see the joint press release) discovered the unique summer climate (atmospheric circulation) pattern only seen in recent years, named circum-Arctic wave (CAW) pattern, which drives co-occurrences of European heatwaves and large-scale wildfires with air pollution over Siberia and subpolar North America (Alaska and Canada). His research team used the Japanese climate model (MIROC5/SPRINTARS) to conduct global sensitivity numerical simulations to comprehensively assess for the first time the impacts of increased Siberian wildfires' air pollution (PM2.5) under current and near-future (2030) climate conditions on air quality, climate, and the economy (Yasunari et al., 2024, Earth's Future; see the press release).
He is also working for aerosol measurements in Hokkaido University, including lidar measurement with NIES, aerosol observations such as black carbon, NASA’s AERONET site (as Co-I of the site), etc., there, to keep monitoring air quality and its characteristics in Sapporo, Hokkaido. Also, Dr. Yasunari's group has developed a portable & low-cost PM2.5 measurement system for cold regions (Yasunari et al., 2022, J. Environ. Manage.) and installed the measurement systems in Fairbanks (Alaska, USA), Sapporo, Ebetsu, and Hakodate (Hokkaido), Hirosaki (Aomori), and Nagaoka (Niigata), Japan. The first PM2.5 observation with the measurement system in Qaanaaq, Northwest Greenland, contributed to discussions on the impact of open waste burning on PM2.5 concentrations (Yasunari et al., 2024; see the press release).His group intends to increase more deployments of the installations in the Arctic and cryosphere in the future. His recent interest is wildfires and their air pollutions including factor and impact analyses, which would be essential for these better future projections. His group recently uses machine learning technique for wildfire and PM2.5 prediction.
He was recently awarded the Meteorological Society of Japan — Hokkaido Award (2021), the Hokkaido University President's Award for Excellence in Research and Education (2020) and the Young Scientists’ Prize in the Commendation for Science and Technology (2019) by the Minister of Education, Culture, Sports, Science and Technology (MEXT). Also, he has been awarded the title of "Distinguished Researcher" for the academic year 2022 by Hokkaido University.
