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

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.

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

Held Virtually Globally, week of 12 September 2021

For the 2021 virtual conference, IGAC’s scientific program will center its scientific program around its current working groups and activities.  This will highlight the exciting work being done as part of IGAC, grow the networks of these working groups and activities, and expose new scientists to the year-round work IGAC does. IGAC will also have an open science session for atmospheric chemistry research that does not fit into any current working groups or activities. We hope this will expose any gaps in IGAC’s current activities and serve as a poll for the atmospheric community on the next big questions in atmospheric chemistry. 

Abstracts are open for submission here and are due May 1st, 2021. You may modify abstracts submitted for the delayed Manchester 2020 IGAC conference or delete and submit a new abstract. 

The conference will take place the week of September 12, 2021. An Early Career Research Programme will take place the week before the main conference. A link to register your interest in this program is at the bottom of the abstract submission link.

The WCRP-WWRP Symposium on Data Assimilation and Reanalysis will be held in Bonn (Germany), 13-18 September 2021 alongside the 2021 ECMWF Annual Seminar on Observations. The event is kindly organized by Deutscher Wetterdienst (DWD) at ECMWF’s new location in Bonn.

Abstract submission and financial support applications are now open, with a deadline of 30 April 2021.

The NOAA Global Monitoring Laboratory (GML) is pleased to announce details about the 49^th Global Monitoring Annual Conference (GMAC) and continue our ongoing effort to collaborate and bring the long-term global monitoring community together each year.

The 2021 virtual GMAC (eGMAC) will be held on five consecutive days: Monday, May 24th through Friday, May 28th, 2021, beginning at 12:00PM Mountain Daylight Saving Time (UTC -6). Each session will be ~3 to 3.5 hours long. Sessions will be recorded to allow colleagues in all time zones to view the presentations after the session concludes.  

Each day will have the following format plus a few short breaks:

• 6 scientific talks (12 minutes each, plus 3 minutes for questions)
• Virtual discussion rooms with the oral presenters
• Virtual poster session to include:
  • 90-second lightning talks for each poster to begin the session
  • Virtual presentation/discussion room unique to each poster

Registration is now open! If you plan to attend any of the sessions, please register on the eGMAC website: https://www.esrl.noaa.gov/gmd/gmac/register.php

Registration will be required to access links for the daily presentations and discussion rooms.

GML is happy to accept abstract submissions for oral and poster presentations again this year. Due to the virtual format, approximately 30 oral presentations will be chosen. All abstracts that are not chosen for oral presentations will be offered poster presentation slots. Poster presenters are encouraged to only submit one abstract unless they have a strong co-author that can host the virtual poster presentation room on their behalf.  

The eGMAC’s agenda is largely driven by the abstracts we receive – GML strongly encourages scientists at all points in their career to submit an abstract and we look forward to your contribution.

Abstract submission is now open! The abstract submission deadline is Monday, April 26th.  Submit your abstract at: https://www.esrl.noaa.gov/gmd/gmac/abstract.html

If you have any questions, please contact the 2021 eGMAC Organizing Committee or visit the eGMAC website:  https://www.esrl.noaa.gov/gmd/gmac/index.html
