WCRP/DCMIP Summer School on Earth System Model Development – August 10-14. 2020 – NCAR

Joint WCRP and DCMIP Summer School on Earth System Model Development: Dynamical cores and physics-dynamics coupling

 

Dates: August 10-14. 2020

Location: Mesa Lab, National Center for Atmospheric Research (NCAR), Boulder, CO, USA

The Dynamical Core Model Intercomparison Project (DCMIP) and its joint World Climate Research Programme (WCRP) Summer School highlights the newest modeling techniques for global Earth system models. The overarching theme of this summer school is physics-dynamics coupling.

The objectives of the joint WRCP and DCMIP Summer School are (1) to teach a group of 30 extraordinary multi- disciplinary students and postdocs how today’s and future atmospheric models are or need to be built, and (2) to use idealized test cases to expose selected model design choices in simplified modeling frameworks based on NCAR’s Community Earth System Model (CESM) and the Department of Energy’s (DOE’s) Energy Exascale Earth System Model (E3SM). DCMIP-2020 thereby continues the DCMIP-2008, DCMIP-2012 and DCMIP-2016 model intercomparison and summer school series as well as the 1st and 2nd WCRP summer school series on Climate Model Development.

The application period will open on March/31/2020 and will stay open until May/1/2020. Invitations to the summer school will be sent by mid May 2020.

MORNING SUMMER SCHOOL

Morning lectures from experts in the field on select topics associated with atmospheric model theory, design and development. Topics include:

– Introduction to Earth System Modeling
– Numerical methods
– Computational performance + challenges
– Physics parameterizations
– Diffusion, filters and fixers
– Physics-dynamics coupling
– Invariant conservation
– Tracer transport
– Model verification and validation

AFTERNOON WORKSHOP

Practical hands-on afternoon sessions run by model leads where students will execute and explore the dynamical cores of CESM (for example, NOAA’s FV3 dynamical core and NCAR’s version of the spectral-element dynamical core) and E3SM (DOE’s non-hydrostatic spectral-element dynamical core) in a simplified model framework. Test cases include Held-Suarez, aquaplanet, radiative-convective equilibrium, and weather forecast experiments.

Announcement of the TOAR Open Comment Period

The Tropospheric Ozone Assessment Report (TOAR:  http://www.igacproject.org/activities/TOAR) is a current IGAC activity with a mission to provide the research community with an up-to-date scientific assessment of tropospheric ozone’s global distribution and trends from the surface to the tropopause.

Guided by this mission, TOAR has two goals:

  1. Produce the first tropospheric ozone assessment report using all available surface observations and based on the peer-reviewed literature and new analyses.
  2. Generate easily accessible, documented data on ozone exposure and dose metrics at hundreds of measurement sites around the world (urban and non-urban), freely accessible for research on the global-scale impact of ozone on climate, human health and crop/ecosystem productivity.

The report is being written as a series of eight stand-alone publications to be submitted for peer-review to Elementa:  Science of the Anthropocene, an open-access, non-profit science journal founded by five US research Universities and published by University of California Press (www.elementascience.org).  As the papers become available each will be posted to the TOAR webpage, listed above, for a 30-day open comment period.  We invite members of the atmospheric and biological sciences communities as well as the general public to read the papers and provide comments if they wish to do so.

One more TOAR paper has just become available for open comment:

Call for nominations for the Steering Committees of emerging GAW Initiatives

The Global Atmosphere Watch (GAW) Programme of the World Meteorological Organization (WMO) through its Implementation plan for 2016-2023 embarked on the development of new environmental products and services for the user community. These are to be implemented through the translational scientific initiatives, namely the Integrated Global Greenhouse Gas Information System, IG3IS (ig3is.wmo.int), Global Air Quality Forecasting and Information System (GAFIS) and Measurement-Model Fusion for Global Total Atmospheric Deposition (MMF-GTAD).

The Environmental Pollution and Atmospheric Chemistry Scientific Steering Committee (EPAC-SSC) that coordinates the work of GAW, is seeking nominations for the Steering Committees of the above mentioned initiatives to guide and facilitate their scientific and technical implementation. Please find a short description of each initiative below.

The Steering Committees of each individual initiative (one team per initiative) shall contain regional representation and reflect diversity in gender and other aspects. With this announcement, EPAC-SSC encourages scientists to apply for the 15 seats on the individual Steering Committees, with rotating membership terms of 2 or 4 years. All members will be selected through this call. Members who contributed earlier to the initiatives are encouraged to apply. Nominees are expected to devote sufficient time and effort to allow for regular participation at the initiative’s events and shall actively engage in the development and promotion of GAW activities. They can be at different stages of their scientific career but must have peer-reviewed publication records, demonstrating expertise in the realm, relevant to the particular initiative. Specializations of the Nominee’s research or operational activity should be related to one or more of the following: atmospheric chemistry, greenhouse gases, forecasting, inverse modelling, data assimilation, air quality and health, atmospheric deposition, food security, climate, data analysis. Self-nominations must be made by 29 February following the template below. If you are interested in nominating an individual (other than yourself) please use the same template.

The nomination form is available here.

Please direct any questions to the EPAC-SSC Chair Prof Greg Carmichael.

ECS opportunity: 2020 IGAC Early Career Short Course

Since 2016, IGAC has hosted an Early Career Short Course (ECSC), which is an intensive three-day course, prior to the IGAC Science Conference. The Short Course brings together some of the most promising early career atmospheric scientists from across the globe in order to cultivate and educate the next generation of leading atmospheric scientists. The Short Course aims to build on the strong scientific education and research early career scientists receive during their Ph.D.s and post-docs by introducing complex ideas, concepts, and skills that will allow these early career scientist to become successful established scientist and contribute to the international community and to a sustainable planet.

The 2020 IGAC Early Career Short Course will take place the three days prior (11-13 September 2020) to the 16th IGAC Science Conference in Manchester, UK.  A select group of 40 future leaders in atmospheric chemistry will attend the early career short course. The scope and design of the short course is being determined by an organizing committee comprised of early career scientists from around the world.

More information about the 2020 IGAC ECSC and prior short courses.

If you have any questions regarding the short course, please send an email to .
