This is the second announcement for the 2022 SPARC Gravity Wave Symposium, scheduled to be in the week of March 28th – April 1st 2022 starting on the morning of March 28th and departing after lunch Friday April 1st. The conference site (https://www.evangelische-akademie.de/tagungshaus/) is located in the medieval center of the vibrant city of Frankfurt: https://frankfurt.de/english/about-frankfurt

At the same time, we will continue monitoring the development of the COVID-19 pandemic and decide in due time whether we move fully to an online format or whether we will go for a hybrid solution, offering all those participants online participation who do not want or are not able to do the trip (decision dates see below).

This SPARC symposium is a continuation of a series of successful similar GW meetings lead-organized by Kevin Hamilton, Joan Alexander, Kaoru Sato, Fuqing Zhang and others over the past couple of decades. The tentative title of the next year’s symposium will be “Atmospheric gravity waves: towards a next-generation representation in weather and climate models”. Research on all aspects of atmospheric gravity waves, including newly emerging topics, will be welcomed but some particular emphases will be given to measurements, simulations, and numerical and theoretical developments, especially those confronting, challenging, and advancing the present-day treatment of gravity waves in atmospheric models.

The web site of the meeting (with information on travel and lodging to be placed there in due time) is

https://www.sparc-gw-symposium-2021.iau.uni-frankfurt.de/

Limited travel-support funds for early-career scientists are available. Those concerned will be asked to submit an informal application together with an abstract of the work they want to present (deadline see below)

The time line of key dates is as follows:

• End of September 2021: Call for abstracts
• October 31st 2021: Support application deadline
• November 15th 2021: Abstract submission deadline
• December 13th 2021:
  • Finalization of the program.
  • Decision on early career travel support applications.
  • Decision whether the meeting will be fully online, without on-site component. This will only be the case if the pandemic makes travelling impossible even within Europe.

A 3rd announcement (call for abstracts) will be circulated in September 2021.

Co-conveners: Ulrich Achatz, Joan Alexander, Kaoru Sato, Laura Holt, and Riwal Plougonven
Meeting secretary: Aurelia Müller

We look forward to your participation.

Best Regards,

Ulrich, Joan, Kaoru, Laura, and Riwal

As part of ESA’s commitment to develop and build satellite missions that push the boundaries of satellite technology and Earth science, four new mission ideas – Cairt, Nitrosat, Seastar and Wivern – have been selected to enter pre-feasibility study and compete to be the eleventh Earth Explorer mission.

Cairt – short for changing-atmosphere infrared tomography – would provide the measurements needed to make a necessary step change in understanding the links between climate change, atmospheric chemistry and dynamics in the altitude range of about 5 to 120 km. It would focus on the processes that couple atmospheric circulation, composition and regional climate change, providing critical observations not available from existing or planned satellite missions. Cairt would be the first limb-sounder with imaging Fourier-transform infrared technology in space.

Pre-feasibility studies will start in due course, after which further down-selections will be made in 2023 and 2025, with a view to launching the successful Earth Explorer 11 mission in 2031–2032.

The Agency has now opened a call for membership to the four respective Mission Advisory Groups (MAGs). These groups will be established after summer to advise ESA on the respective mission concepts.  Mission Advisory Groups play an active role in providing advice on activities supporting the scientific definition and preparation of the mission concept during consolidation and preparation of the mission requirements.

The Call is open to scientific experts with relevant scientific or technical expertise, with nationality and residence in one of the 22 ESA Member States.

The strict deadline for submission of applications is 5th July 2021, 12:00 (noon) CEST. Early registration is encouraged.

Further information on the mission candidates and the role and terms of reference of the MAGs is provided on the Call website: https://missionadvice.esa.int/

The organising committee of the Conference announces today that the GCOS/WCRP Climate Observation Conference is postponed.

It has become clear that after more than one year of continual virtual meetings, we are all suffering from “Zoom fatigue”. It has been difficult to develop an online format that allows experts to present their papers and allow the discussions we would like to foster. This was also reflected in the number of submitted abstracts.

In the coming months, we will be working towards a new event format which allows experts from around the world to fully engage and interact, with the prospect of holding the Conference in 2022. This would also give us the opportunity of celebrating the 30th Anniversary of GCOS.

This difficult decision has been taken after careful consideration and consultation with the sponsoring programmes GCOS and WCRP and the supporting organization EUMETSAT.

We sincerely thank those who have put time and effort into their registration and we apologise for this delay. We are contacting those who submitted an abstract: their contributions will be considered for the new conference.

The new date of the Climate Conference will be announced in due time on the same website: https://www.eventsforce.net/gcos-coc.

We encourage you to join us then and look forward to seeing you all there, stay tuned!!!

The World Climate Research Programme (WCRP) leads the way in addressing frontier scientific questions about the coupled climate system — questions that are too large and too complex to be tackled by a single nation, agency, or scientific discipline. For almost 40 years WCRP has coordinated international climate research to advance our understanding of the climate system and how it is affected by human activities. The decades ahead will bring challenges that can only be addressed through a worldwide coordinated effort, involving co-design and stakeholder engagement conducted by a prepared scientific workforce, to support mitigation strategies and adaptation planning. This is one in a series of regional forums, where we will exchange ideas, discuss new activities and opportunities being developed by WCRP, and explore ways that our community of scientists, partner programs, funders, and end-users of our climate science can engage to meet these challenges.

This Forum will begin with an overview of WCRP from the Vice Chair of the WCRP Joint Scientific Committee (the scientific steering body of WCRP) Helen Cleugh, followed by talks highlighting climate science priorities and opportunities for collaboration in the Southeast Asian Region:

• CORDEX-SEA: Providing regional climate change information for enabling adaptations in Southeast Asia, Fredolin Tangang, Professor and Chairperson, Department of Earth Sciences and Environment, the National University of Malaysia and CORDEX-SEA Coordinator.
• Climate science and information priorities and needs – researcher and end user perspectives, Ardhasena Sopaheluwakan, Director, Center for Applied Climate Services, Meteorological, Climatological and Geophysical Agency, Indonesia.
• Climate science as decision-support for resilience: transdisciplinary approaches from local to global, Jessica Dator-Bercilla, University of the Philippines in the Visayas and Asia Climate Change Consortium.
• From science to action: bridging researchers and practitioners, Rodel Lasco, Oscar M. Lopez Center and Philippines Country Coordinator for World Agroforestry (ICRAF).

This will be followed by a moderated question and answer session, with time for discussion. The Forum is without charge and is open to all, but we do ask that you register your interest.
