During Aug. 7th-Aug.8th, Yoshimura’s Lab and Yamazaki’s Lab had held the KK summer intensive seminar at Ritsumenkan University on Aug.7th. 
Yoshimura sensei gave a introduction talk at the beginning and Yamazaki sensei concluded at the end of the seminar. Students from Yoshimura’s Lab and Yamazaki’s Lab had given their presentations on the seminar and received from their supervisors and colleagues.
 

On Aug.8th, all members  had a trip to  the Fukui Prefectural Varve Museum and Mikata Five Lakes. At the museum, Nakagawa sensei gave us a talk about the varves and his out-coming research results considering the global climate change.

On July 22, a seminar was held with Korea National University of Transportation, Korea University and Incheon University.

The schedule was as follows:

16:00-16:30 Dr. Jongmin Park (The use of C-band SAR to explore water body, water level, and soil moisture)

16:30-17:00 Dr. Kyuhyun Byun (Reconstruction of Long-Term High-Quality Gridded Meteorological Datasets based on Deep Learning)

17:00-17:30 Two post-docs from Dr. Jun’s lab

1. Impacts of Rossby Wave Packets and Atmospheric Rivers on Meteorological Drought (Dr. Jungwoo Han)

2. Retrievals and analysis of satellite-based evapotranspiration (Dr. Jongjin Baik)

17:30-18:00 Q&A, General discussion

18:30- Socializing dinner

This event was a good opportunity to find out better what is being done in South Korea, but also to learn how our research is connected and how we can collaborate. 

Members in the seminar

Ylab welcomes new students, post-docs and professors with a little party!

We hope that in the near future you can create strong connections within the lab. These will not only support you academically, but also as friends when you need them.

Welcome Party in May

Welcome Party for Diego in June

The project brochure for the research project led by Yoshimura, “Implementation of Long-Term Flood Prediction through the Integration of Satellite Observations and Model Simulations: Toward the Realization of a Society Free from Flood Disasters” (JST/Future Society Creation Project Full-Scale Research/JPMJMI24I1), has been completed.

This brochure provides an overview of long-term flood prediction technology and introduces the future that this technology could bring to our region once it is implemented in society. The future vision was created through discussions among researchers and practitioners from various fields who are members of this research project. Please take a look.

Undergraduate student participants with Prof. Yoshimura and TAs

while working

The Kashiwa Campus Science Camp 2025 was held in February and provided a valuable opportunity for undergraduates to gain unusual research experience. Four undergraduates from the Yoshimura Lab participated in the camp, and although it lasted only four short days, they were eager to learn and worked hard with Prof. Yoshimura and the TAs. The final day came and went in a flash, and even with the limited time, the presentations by the undergraduates were excellent and impressive.
