#1. Foreword by Yukihiro Takahashi, President of JpGU

The deadline for submitting abstract for the 2024 JpGU meeting has
passed, with the exception of some late-breaking sessions. I would
like to take this opportunity to thank you very much for the large
number of submissions we have received, almost as usual years.
On the other hand, I feel that Japanese participants at AGU and
EGU meetings are becoming relatively minor, in contrast to South
Korea and other Asian countries. The number of participants from
Korea at last AGU 23 meeting was 3rd, while Japan was in 5th or
6th place. EGU shows the number of participants by country on the
website. It’s difficult to read statistics during/after the COVID
period, so I looked at trends from 2009 to 2019. The number of
Japanese participants has always been around 200, with no major
trends in increase or decrease, but that of South Korea increased
from 41 in 2009, surpassed that of Japanese in 2014, and reached
391 in 2019. In addition, China had 70 participants in 2009, but in
2019 it rose over 1,100, which is more than the United States, and
Taiwan also had 258 participants in 2019, which is more than Japan.
I think this may be due to the fact that it is difficult for Japanese
researchers to participate in EGU general assembly due to the busy
time period in Japan, but I think it is undeniable that our relative
presence has declined. Even though we say that Japanese society
s losing its vitality, it feels a little sad when we consider that
the GDP is the fourth largest in the world, and the population is
twice that of South Korea and four times that of Taiwan. Also, the
other day, I had a meeting with 10 representatives
at the executive committee meeting of geoscience society presidents,
and several societies said that their membership numbers were at
half or 60% of their peak levels. The number of researchers in
Japan and the total amount of research funding have not changed
that much, so what is happening in Japan now, or how is Japan being
left behind by the rest of the world? I feel that the time has come
to reexamine what we should think and how we should act.

#2. 2024 Meeting Information

(1) Late-Breaking Session to be held!

On 1 January 2024, an earthquake of M7.6(JMA)occurred with its
hypocenter beneath northern Noto Peninsula. The earthquake caused
devastating damages throughout the Noto Peninsula and tsunamis were
observed widely along the coasts of the Sea of Japan, including
occurrences of landslides, fires, liquefaction, etc. in many areas.
These hazards resulted from the Noto Peninsula earthquake are relevant
to a wide range of fields in Earth and planetary sciences. JpGU
announces holding late-breaking sessions as Public and Union Sessions
in order to provide a forum for information sharing and discussion.
Details of the scope will be posted on the meeting website as soon as
they are ready.

(2) Working Group for the Japanese Society for Artificial Intelligence
(JSAI) Competition

GeoSciAI2024 ~Challenge for deep learning model development in the
earth and planetary science~

The Japan Geoscience Union and the Japanese Society for Artificial
Intelligence will jointly host a model development competition in
Geoscience! In recent years, AI technology has developed remarkably,
which affects the vast research fields. Geoscience is a research
field where various physical, chemical, and biological phenomena
are intricately intertwined, and the information is vast and diverse
in terms of both quantity and quality. Therefore, the contribution of
AI technology is becoming extremely significant in recent geoscience.
This competition aims to promote the integration of the geoscience
and information science through a model competition event.

There will be one proposal each from the earthquake, the meteorology,
and the space weather field.
Participants are required to register through the web page and submit
a technical paper summarizing the model development and results.

Anyone can participate in the competition
#You do not need to be a member of JpGU or JSAI

Late January 2024: Open of web page and each task
April 2024: Release of evaluation data, Technical paper instruction
Early May 2024: Deadline for submission
Late May 2024: Notification of results, Award Ceremony @ JpGU 2024
