Announcement: Workshop on ‘Attribution of multi-annual to decadal changes in the climate system.’ 22-24 Sept 2021

We would like to bring to your attention the WCRP Explaining and Predicting Earth System Change Lighthouse Activity Workshop on ‘Attribution of multi-annual to decadal changes in the climate system.’ The workshop will take place online, from 22-24 September 2021. 

The aim of this workshop is to document current research, identify challenges, and explore potential pathways towards building an operational capability to attribute multi-annual to decadal changes in the climate system on global-to-regional scales. The attached first circular gives an overview of the key areas that will be addressed during the workshop. A second circular with registration details will be issued towards the end of April.

New: improved Fortran and Python decoding programs for high vertical-resolution radiosonde data

In SPARC Newsletter number 56, Geller et al. (2021) described increased high vertical-resolution radiosonde data that is now available to the global research community, and in that article they described how to access those data. Mr. Bruce Ingleby has now developed improved Fortran and Python decoding programs for those data. They can be accessed from https://confluence.ecmwf.int/display/ECC/bufr_read_tempf ‘. Future developments will be described as they become available.

Announcement: WCRP Open Science Conference: early 2023

Dear colleagues,  
  
We are delighted to share with you the First Circular of the WCRP Open Science Conference, to take place in early 2023 (download flyer). This conference will showcase the work that all of you are doing, right across WCRP and with partners. In particular, it will highlight the importance of climate science for decision-making and responding to a changing climate. This Conference will, of course, celebrate the work of the WCRP Grand Challenges, which will sunset at the end of 2022. At the same time, it will roll out the new WCRP and will be dedicated to the next generation of climate scientists. It will also include events that cater to the general public.   
  
In the next weeks and months we will continue with the planning of the conference, including identifying a host for the in-person part of the meeting and the establishment of a science planning committee. Conference planning will be supported by dedicated staff who will be hired specifically for this purpose using external funds.  
  
Kind regards  
  
Detlef Stammer and Helen Cleugh

Announcement: PACES Open Science Meeting 26-28 May 2021

The 4th PACES Open Science meeting will be held 26-28 May 2021 in an online format. We are planning for a more limited meeting than in past years, to account for the wide range of time zones that may wish to participate. However we still expect a full programme of science presentations across the full range of PACES science topics, and we will also make some time for virtual posters and discussion. We would also like to review progress across the PACES working groups, and provide opportunity for engagement in these activities. 

The meeting sessions will take place as follows:

26 May: 11:00-14:00 UTC
27 May: 12:00-15:00 UTC
28 May: 13:00-16:00 UTC

The programme will cover:  Arctic climate impacts of air pollution, Arctic-mid latitude linkages, long-range pollution transport to the Arctic, aerosol-cloud interactions in the Arctic, Improving observational capacity, Local Arctic air pollution sources and processing (including the forthcoming ALPACA project), Arctic urbanisation and air pollution.

As in previous meetings, the emphasis will be on getting together as a research community and sharing new analyses and progress on these different topics. 

Registration will open in mid-April, so please look out for a further announcement, which will also include a draft scientific programme and information on keynote speakers.  

Please save the date(s)! 

Best wishes,
Steve and Kathy, PACES co-chairs.

(on behalf of the PACES Steering Committee)

PACES is an IGAC and IASC co-sponsored initiative, which aims to review existing knowledge and foster new research on the sources and fate of Arctic air pollution, its impacts on climate, health, and ecosystems, on the feedbacks between pollution and natural sources, on climate responses, and on societal perspectives.

Abstract submission open: ESA Water Vapour Climate Change Initiative (WV_cci)

User workshop; 14 – 18 June 2021 – online

Topic: Challenges around atmospheric water vapour

Abstract submission & registration now open at https://events.spacepole.be/event/122/

Background:

The Water Vapour Climate Change Initiative (WV_cci) is a project of the European Space Agency (ESA) with the overall goal to generate climate data records (CDRs) of atmospheric water vapour for use in climate applications. The project develops, validates, and releases quality-controlled, long-term CDRs of total column water vapour (TCWV) and water vapour profiles in the stratosphere (2D), as well as a five-year data record of water vapour profiles in the troposphere and lower stratosphere (3D).


Objectives:

The aim of the workshop is to bring together the broader water vapour community, including those interested in the generation of water vapour CDRs and data users (such as climate modellers and NWP researchers) in order to discuss the most recent scientific applications and challenges in processing and using water vapour CDRs. Topics of the workshop include:
• Discuss challenges related to the generation of water vapour CDRs.
• Show-case climate user applications of water vapour CDRs (with focus on WV_cci CDRs).
• Collect and update user requirements for atmospheric water vapour.
• Present and discuss results from climate analysis, climate applications, and process studies using water vapour CDRs.


Format:

The workshop will be carried out online and will consist of a series of presentations and discussion blocks. It is foreseen to have the workshop in the week 14–18 June 2021, at 14– 18 CEST. The exact number of days will depend on the number of submitted abstracts.

Important dates:

Abstract submission deadline:05 May 2021
Registration:31 May 2021
