[ACG45-P05] Implementation of the AsiaPEX activities: Discussion toward the Asian Monsoon Year-II
キーワード：フィールドキャンペーン、アジアモンスーン、降水、陸面大気カップリング
The AsiaPEX (Asian Precipitation Experiment) Science Plan was accepted by the GHP (GEWEX Hydroclimatology Panel) in 2023, which is based on a review paper published in BAMS. We are now updating this Science Plan to proceed to the implementation phase of the activities. In this update, we proposed four Goals of AsiaPEX: 1) description and projection of precipitation extremes in the past, present and future, 2) improvement of S2S predictability, 3) prediction of freshwater availability and risks, and 4) coordinated field campaign focusing on Asian monsoon system, as hotspots that will unite all the AsiaPEX participants and attract people to join the upcoming AMY-II. Such goals are also open for discussions in AsiaPEX community and will be improved via discussions.
We are also on the process of well-functioning organized structure of AsiaPEX. We formalized basic structure of the AsiaPEX as shown in the Figure. We will define six Science Panels (Panel-1 to 6) based on our six approaches and five project Work Groups (WG-1 to 5). They will have at least an annual meeting (including online) and will operate as an activity platform for organising research meetings, compiling research results, presenting highlighted research results, making recommendations for field campaigns and applying for funding sources. There will be at least two co-convenors on the panel. We will consider their selection in due course Some cross-cutting mechanisms may also be needed, which may be permanent or temporary. Discussions on how they will function are also important to develop.
The timeline towards the Asian Monsoon Year-II is also a key point of discussion. In the updated Science Plan, we showed a timeline covering whole AsiaPEX period and some details on the first period before the organization of the field campaign, with a plan for the IOP in the latter half of 2020s (Figure). This can be used as a guide for measuring the success of different approaches, showing what is the key, especially for the first period of the AsiaPEX.
Finally, what should be measured at the ground surface? We scheduled a conference around 2026 that should be a focal point of our discussion about the field campaign. AsiaPEX believes that the source of the uncertainty lies in the land-atmosphere coupling processes at the land surface and at the bottom of the atmosphere. This region is the most challenging region for remote sensing and modelling. Therefore, we, AsiaPEX call for a coordinated field campaign AMY-II integrated with remote sensing and modelling activities.
These discussions should start from this session in JpGU 2025, and will be concluded as a plan for the AMY-II by the end of 2026. Let us involve many researchers in this discussion.
