Objectives of ARCDAP-3 Workshop

To develop regional capabilities in evaluating the latest suite of model output from the CMIP6 database

Assess the status of regional understanding of the CMIP databases (CMIP5 and 6)
Obtain a shared understanding of CMIP’s status and latest developments of CMIP6
Be introduced to certain resources for CMIP model evaluation (ESMValTool, Climate Explorer)
Work towards developing a common framework for studying key regional climate processes across a range of climate models
Develop a common understanding of suitable global climate models that can be relied upon for the ASEAN region
Discuss and develop a regional consensus on most relevant emission scenarios to use for regional climate change projection
Link the developed understanding about CMIP databases with existing and on-going projects to generate downscaled climate projections across the ASEAN region

Attaining these objectives will bring the region in line with the latest international standards of assessing climate models. Additionally, it will foster a regional community of data, knowledge and expertise regarding key meteorological and climatological processes influencing the region.

Participation

The total number of participants is likely to range between 35 and 45. Workshop participants will be from the following groups:
(a) Representatives from each of the 10 ASEAN NMHSs or relevant national agencies – 2 representatives per country, ideally climate scientists with expertise in using climate data, and/or climate modelling, and/or analysing climate processes and using in-situ data.
(b) International experts who have been leading the development of the CMIP database (e.g. World Climate Research Programme (WCRP) CMIP Panel) and experts in key regional climate processes relevant to the ASEAN region.
(c) Producers and experienced users of regional climate models (CCRS and local experts from other Research Institutions in Singapore as well regional colleagues, e.g. contributing to CORDEX-SEA).
(d) Representatives from end-user sectors (e.g. AHA Centre) and the ASEAN secretariat.
(e) Representative(s) from the relevant WMO Technical Commission.

Proposed Structure for the ARCDAP-3 Workshop

A 4-day virtual workshop will be conducted from Monday the 15th to Thursday the 18th of March 2021. The workshop will be hosted virtually by CCRS over the Zoom videoconferencing platform. The GitHub platform will also complement the workshop as a repository for accompanying workshop material and presentations. The programme for each day will commence at 1030 hrs (SGT) and end no later than 1535 hrs (SGT) to accommodate regional and international participants from various time zones.

Day 1 Introduction to CMIP/ Presentations by NMHSs on experiences with GCMs	AM (Introduction: welcome, opening address, workshop goals and structure) Introduction to CMIP history CMIP6 database: design, current status and future progress Support, tools and information for obtaining CMIP6 data Advances in modelling (high resolution and other MIPs of interest)/ (if suitable experts invited) Model/ scenario and observational uncertainties PM (Presentations by NMHSs on their GCM experience) Past and current projects in support of national level studies, etc Either through exploration of CMIP database or through direct engagement with international modelling groups Knowledge and experience using CMIP6 (if any) in particular Review of progress made in terms of adopting best practices from ARCDAP-1
Day 2 Presentations by NMHSs on experiences with GCMs/ CMIP for evaluating regional climate processes	AM Presentations by NMHSs on their GCM experience (cont.) PM (Presentations by experts in using CMIP to evaluate processes and their experiences) Individual talks on important climate processes that are important for participants to understand, e.g. ENSO, IOD, MJO etc. and findings from previous work Participants from NMHSs will be invited and encouraged to share about their previous work on evaluating climate processes
Day 3 CMIP for evaluating regional climate processes/ Applying CMIP to studying climate projections	AM Presentations by experts in using CMIP to evaluate processes and their experiences (cont.) PM (Presentations by experts on suitable experiments in CMIP6 for projection studies, how to select suitable GCMs and relevant ESMValTool recipes and tools) Presentations by several NMHSs and agencies/institutes (e.g. CCRS, NAHRIM, IMHEN) on how they have conducted their regional/national climate projection studies and their experiences
Day 4 Applying CMIP to studying climate projections/ Limitations of and future directions for CMIP in ASEAN, regional downscaling experiments	AM (Breakout room discussion on building regional best practices for climate science and producing climate change information and services) General rules/ guidelines for NMHSs to reference Gauge interest in a regional best practices document for CMIP6/climate projection studies/etc What are the most important aspects of best practices? Limitations of CMIP and using GCM output with regards to regional scale information AM (Plenary discussion and expert panel) Reporting from breakout groups Identifying the most important aspects of regional best practices and key takeaways from CMIP6 PM (Presentations by experienced producers or users in regional climate models) Current progress and plans for regional downscaling experiments Scope for using CMIP6 data in the near future PM (Presentation by CCRS on the current plans for ARCDAP-4) Downscaling experiments, decadal variability PM (Discussion amongst participants on future downscaling experiments) Where the current projects are headed, scope for future collaboration and more regular exchanges between project groups? Workshop wrap up: Key messages, results and recommendations (guidelines)
