Session Description: Remote sensing and modeling have transformed hydrologic science and applications. Spaceborne missions are dedicated to interlinked global hydrologic processes. Furthermore, computational techniques are accelerating analyses of these data and integrating them into the modeling. However, there are existing gaps and challenges the hydrologic community faces such as data uncertainties, limited model physics, and inequitable data availability across the world. How will the hydrologic community use these resources to better understand the world's water resources and to overcome related challenges facing society, particularly in Asia and Oceania. In this invited talk session, we will discuss the benefits, challenges, and opportunities of remote sensing for advancing hydrologic research, integrating multidisciplinary and multisensor data, and employing data assimilation and AI/machine learning.

Session Description: The World Climate Research Programme’s (WCRP) Coupled Model Intercomparison Project (CMIP) has coordinated international climate model experimentation, to develop a better understanding of past, present, and future climate change. Over four decades, CMIP has grown in scope and complexity, targeting climate science addressing the WCRP objectives and serving IPCC Assessments. CMIP6, the latest phase, yielded more than 25 PB of data, with contributions from 131 models, from 48 institutions, representing 26 countries.
Work has commenced on future CMIP7 planning. The project aims to meet the growing community needs, enabling climate science and providing actionable climate information to aid policymakers. To facilitate next steps, the two panels that oversee the project, the CMIP and Working Group on Coupled Modelling (WGCM) Infrastructure (WIP) Panels have established seven Task Teams to guide CMIP7 scope and design and facilitate coordinated infrastructure development. These aim to increase CMIP’s scientific and social relevance, widen participation, improve data accessibility, and reduce the carbon footprint.
We invite our growing community to attend. We will describe ongoing planning, highlight engagement, and feedback opportunities, and invite attendee feedback and participation. The town hall will be presented by members of the CMIP Panel, Fresh Eyes on CMIP group, and CMIP7 Task Teams.

Description: The Coupled Model Intercomparison Project (CMIP) is an international climate modelling project, designed to better understand past, present, and future changes in the climate. More than 50 modelling centres around the world participated in CMIP6, which has already generated in excess of 14 PB of unique data. From its inception, there has been a focused effort to make the model intercomparison data available to scientists beyond the climate modelling community. With more data access platforms and analysis tools being created every year to support the use of CMIP data, it can be difficult to know where to begin. Primarily led by members of the new Early Career Scientists group, Fresh Eyes on CMIP, this workshop will provide an overview of ways to access CMIP data and present some useful analysis tools and methods to help with using it. The key topics across the session will cover:
  1. CMIP experimental structure and MIPs.
  2. Scientific limitations of CMIP data.
  3. Different methods for accessing CMIP data, and their advantages and limitations.
  4. Analysis and evaluation tools.
In this workshop, participants will learn about CMIP data and how to access and analyze it efficiently. The session will be interactive with a lot of time to ask questions in between presentations, videos, and live demonstrations. The session is open to anyone who wants to use CMIP data from any sector.

Interdisciplinary Panel: Climate Change and Infrastructure Reassessment
Friday, 28 June 2024 | 2:00pm - 3:30pm | Pyeongchang Hall III, Alpensia Convention Center

Program uses Korean standard time and is 9 hours ahead of GMT (GMT+9)

Disasters occur or are mitigated based on the relative magnitude between the ‘hazard’ factor to drive them and the ‘societal capacity’ factors to withstand them. Non-stationarity in climate, which began to be detected in the late 20th century, have now become widespread to the point that they are noticeable by the general public. In other words, climate change is increasingly recognized as a major driver of extraordinary disasters worldwide, and it has become the focus of numerous studies in almost every country. However, there is relatively less public interest in the societal capacity required to cope with disasters. Vulnerability, especially concerning ‘aging’ social infrastructure, is undoubtedly crucial especially in developed nations with a long history of urban development. In summary, we are confronting to a combined difficulty with two major challenges, the ‘changing climate’ and the ‘aging infrastructure’. Taking South Korea as an example, the first multipurpose dam, Soyanggang Dam, celebrated its 50th anniversary in 2023, and from now on, a multitude of social infrastructure will age beyond 50 years in the coming years. This session is designed to re-evaluate the issue of aging social infrastructures in the context of climate change and to discuss forward-looking scientific and technological alternatives and policy directions to address it.


Workshop: A Mini Tutorial for Ensemble Data Assimilation and the Data Assimilation Research Testbed with Applications for the Model for Prediction across Scales
Friday, 28 June 2024 | 11:00am - 12:30pm | Pyeongchang Hall II, Alpensia Convention Center

Program uses Korean standard time and is 9 hours ahead of GMT (GMT+9)

Convener: Lili Lei, Nanjing University
Instructors: Jeffrey Anderson, U.S. Geological Survey
Soyoung Ha, National Center for Atmospheric Research
Associated Sections: AS, HS, OS (Not Limited To)
Description: This workshop is designed to be a short course that provides a practical introduction to ensemble filters from theories to tools along with realistic applications. There will be two main lectures, one is for “Introduction to Ensemble Data Assimilation” and the other is for “Introduction to the Data Assimilation Research Testbed (DART) and its Applications for the Model for Prediction Across Scales (MPAS)”. Basic ensemble filter algorithms will be covered along with an overview of extensions required for successful application in large earth system models. Various flavors of ensemble filters can be tested through the Data Assimilation Research Testbed (DART), a community software facility for ensemble filter data assimilation. DART can produce high-quality weather predictions but can also be used to build a comprehensive forecast system for any prediction model and observations. DART has been applied to NWP at scales ranging from sub-kilometer to global, but also to space weather, oceans, sea ice, terrestrial systems, hydrologic models, and many other earth system applications. This workshop is open for all participants to AOGS who have interests. Attendees will leave with a solid foundation that will allow them to explore using DART for existing models and observations, especially the Model for Prediction Across Scales (MPAS) for global and regional applications. They will also have a basic understanding of what would be required to develop DART assimilation capabilities for new models or observations.

Abstract
Life has unexpected twists and turns. I became quadriplegic, completely paralyzed neck down, during a geological field trip when the van that I was driving rolled over. We seldom think about it but our existence on this planet is finite in time. The finiteness is said but good because, as Nicholas Humphrey said in his book, if we cannot travel through the sea of eternity, the more significant is this small island that we stand on. Being an earth scientist is a blessing because we understand the vastness of time and space and appreciate what it took for life to begin some 4 billion years ago on this barren planet and for such life to advance into a universal civilization. At the same time, we are constantly reminded that the advanced civilization that we built can be wiped out suddenly by Mother Nature. I became a big-picture person after my accident 18 years ago. In this talk, I would like to share my thoughts and emphasize the values we must uphold as global citizens.

Abstract
Jupiter's mid-infrared north polar hot spot, ~20 K warmer than the surrounding polar stratosphere, has been observed for over four decades. Its unusual appearance and longevity have not been fully understood, although several mechanisms have been proposed to explain its existence. We utilized the Gemini Near-Infrared Spectrograph at Gemini/North telescope to spectrally map Jupiter in the 3-micron emission lines of CH4 (methane) and C2H6 (ethane) across Jupiter's northernmost latitudes where its mysterious north polar hotspot is located. These lines are emitted high above the stratosphere and are excellent monitors of auroral energy being deposited downward into the stratosphere. By comparing the emission from CH4 with that from C2H6, we demonstrate that the transient heating and bright line emissions from these molecular species are caused by increased precipitation of high-speed auroral particles, which are produced in Jupiter's turbulent magnetosphere and ionosphere near its poles. The heating extends down into the stratosphere where the hotspot is located. At that depth, heating up and cooling off is much more gradual than at higher altitudes. Additionally, the free flow of warm gas in the hot spot to the surrounding polar regions is resisted by recently detected polar stratospheric jets associated with polar fronts. Other heating mechanisms proposed in the literature, such as Joule heating, polar haze heated by sunlight, etc., seem only the secondary mechanisms that follow atmospheric ionization caused by the energetic particle bombardment.

It is situated along Dong River surrounded by beautiful limestone karst area (Figs. 1 & 2). The Cave has been open to public past 8 years since 2010, and it has about 15,000 visitors annually. It is the cave that is still actively forming with beautifully decorated stalactites, stalagmites, flowstones, anthodites and many kinds of other speleothems. During rainy season, the floor can be submerged by water from the Dong River through the collapsed hole connected to the river.

Figure 3. Carbonate speleothems at the large chamber in Passage A. (copyright, Cave Research Institute of Korea)

Figure 4. Stalactites, stalagmites, and columns in Passage A. (copyright, Cave Research Institute of Korea)

Most of the passages show domal in cross section showing the typical shape of vadose passage, even though other shapes are also observed. This cave has been mostly developed along joint planes, whereas some parts of the passages were influenced by strike directions of bedding planes. Cave sediments are mostly composed of muddy sediments with minor contributions of sands and gravels where cave streams are present. Mineralogically, quartz, calcite and illite are dominant minerals in cave sediments.

Various speleothems such as soda straws, stalactites, stalagmites, columns, flowstones, rimstones, cave pearls, curtains (and bacon sheets), helictites, anthodites, cave corals, cave shields, and calcite rafts, etc., are present. Especially, some stalactites and stalagmites with erratic shapes as well as fried-egg stalagmites are the most peculiar speleothems in this cave (Figs. 3-8).

All the distribution of the speleothems are described separately on the floor and on the wall and ceiling. Mineralogy and texture of the speleothems are shown only for the speleothems collected (already broken speleothems). Among the speleothems studied, soda straws, stalactites, stalagmites, rimstones, curtains and rafts are only composed of calcite, whereas cave corals and cave shields are either composed of calcite or of both calcite and aragonite.

Description

The Hantangang River UGGp was designated as a UNESCO Global Geopark in 2020. The Hantangang River Geopark is located between two tectonic segments - the Imjingang Belt and the Gyeonggi Massif - at the center of the Korean peninsula, giving way to the geodiversity of the Precambrian, Palaeozoic, Mesozoic, and Cenozoic igneous, metamorphic, and sedimentary rocks which contrasts with other UNESCO Global Geoparks. The most important feature of the Hantangang River Geopark is the Quaternary lava plateau distributed both in South and North Korea through the DMZ. The Hantangang River is a linearly developed stream system along the Chugaryeong Fault System. It shows a unique topography formed by the combination of geological structures, volcanic topography, and river terrain formed by basalt lava flowing along the paleo-channel, which is very rare. This also shows us the linkage of ecological, archaeological, historical, and cultural values with the geological value of the Hantangang River Geopark.

Mentoring Program

AOGS has a Mentoring Program for students and is considering expanding it to post-docs and Early Career Researchers (ECRs). It was formerly called Meet-the-Experts. This program attempts to link Undergraduate and Post-graduate students (MS and PhD) with more senior researchers in their field. Other activities will be held throughout the year outside of the AOGS conference.

For Mentees (Students)

Undergraduate and Post-graduate students (MS and PhD) are invited to meet experts in their section as part of the Meet-the-Experts (MTE) program. “Your” Expert will contact you before the meeting to set up a date and time to meet during the conference. To participate, please sign up during registration and provide the following information: your name, AOGS section, year, university, country and abstract number (if you are presenting). We will match you up with a mentor, as much as possible. This is an opportunity to meet people in your field and get contacts for future research, post-graduate study, or post-doctoral positions. Don’t worry about your English skills. We believe that participating will greatly enhance your experience at and involvement in the meeting.

For Mentors

For the Mentoring Program to work, we need Mentors to volunteer. Student(s) will be associated with Mentors based on their expertise. The email addresses of the students will be given to the Mentor(s) in order for the Mentor(s) Experts to arrange a date and time to meet those who fits with their schedule. To participate, please sign up during registration and provide the following information in details: your name, AOGS section, year, university, country, abstract number (if you are presenting). We will match you up with student(s), as much as possible. The contact will be sent ahead of time.

If you are looking for post-docs, you can look at this as the potential for an informal interview. You can make this as involved as you like. As a minimum, please meet the student sometime during the week and see their poster or presentation. You might want to go to lunch with them so you can have an extended chat on their research and interests. You might ask them for one of their paper(s). It is up to you to decide how involved you want to be. As for the time investment, it might save you time in the future to find out about a future collaborator or post-doc. You can get a lot more information on them this way than from a CV and/or a Skype, Zoom, Teams interview.

Please volunteer and participate.
