2019 CATCH Open Science Workshop
7-8 December 2019
University of California, Berkeley, USA

An important objective of this workshop is to gather ideas and community support to develop CATCH working groups in order to focus research on emerging CATCH topics and research challenges. Therefore, this is a working workshop and all participants will have an active participation role. We are not collecting abstracts, but rather titles of presentations that participants would like to give. Following registration we will put together an agenda with talks, posters, and discussion sessions. Participants will be notified of their presentation type a month prior to the meeting. You are also welcome to attend without giving a presentation and your input to the working workshop will be through the discussion sessions in addition to Q&A during the oral and poster presentations.

There is limited funding available for travel support. Please only apply for travel support if you absolutely need it. Priority for travel support will be for early career scientists (current graduate student or within 4 years of receiving a PhD, excluding career breaks) and scientists from scientifically emerging countries.

Registration Information:

Registration fee: $150.00 The registration fee includes lunches and coffee/tea breaks for two days, and a group dinner on 7 December. Registration closes:  11 October 2019

Cancellations will include a $20.00 fee The CATCH Open Science Workshop is limited to 120 participants. If there are more than 120 registrations, the registrations will be evaluated. If your registration is declined, you will receive a full refund for the registration fee.

The CODATA 2019 Conference will be held on 19-20 September 2019 in Beijing, China.

This year’s conference theme is: Towards next-generation data-driven science: policies, practices and platforms.

The conference will follow a high-level workshop, 17-18 September 2019, on ‘Implementing Open Research Data Policy and Practice’ that will examine such challenges in China and elsewhere in the light of the emergence of data policies and in particular the China State Council’s Notice on ‘Measures for Managing Scientific Data’.

Towards next-generation data-driven science: policies, practices and platforms

Science globally is being transformed by new digital technologies.  At the same time addressing the major global challenges of the age requires the analysis of vast quantities of heterogeneous data from multiple sources.  In response, many countries, regions and scientific domains have developed Research Infrastructures to assist with the management, stewardship and analysis.  These developments have been stimulated by Open Science policies and practices, both those developed by funders and those that have emerged from communities.  The FAIR principles and supporting practices seek to accelerate this process and unlock the potential of analysis at scale with machines.  This conference provides a significant opportunity to survey and examine these developments from a global perspective.

The convening organisations are pleased to invite you to contribute to the program by proposing presentations and posters.  The deadline for proposals for presentations and posters is 8 July 2019: https://conference.codata.org/CODATA_2019/submit/

Organised by the LASG/IAP, the second GOTHAM Summer School will train young scientists on a unique combination of interdisciplinary scientific topics and tools relevant for understanding teleconnections and their role in causing extreme weather events. The school comprises lectures as well as tutorial sessions by some of the world’s leading experts in this field.

Specific topics include:

• Fundamental dynamics in the teleconnections
• Global consequences of extreme El Niños
• Mid-latitude weather extremes and the role of tropical extratropical and Arctic drivers
• Stratosphere dynamics and stratosphere-troposphere interactions
• Internal variability and external drivers of South and East Asian systems
• Interactions between global teleconnection patterns.

Participation

The Summer School is intended to host 30-40 young researchers woeking in relevant topical areas, both frim GOTHAm partners and external institutes. Registration is free-of-charge and accommodation expenses will be covered for all arrendees. Participation is applied through website http://project.lasg.ac.cn/gotham.

the workshop will be held at ECMWF in Reading on 18-21 November 2019

This workshop will bring together experts to discuss and propose ways forward in representing the stratosphere in current and future numerical weather prediction models (1-50 km resolution, forecast lead times from medium-range to seasonal), and pathways by which better treatment of the stratosphere can improve predictive skill in the troposphere.
