System for Integrated Modeling of the Atmosphere (SIMA) Virtual Workshop

Post by mgduda » Fri May 22, 2020 10:47 pm

Dear Atmospheric Modeler,

We are pleased to announce that NSF (National Science Foundation) and NCAR (National Center for Atmospheric Research) are jointly organizing a 2.5 day virtual workshop from June 29 to July 1, 2020 to communicate and discuss the development of a new unified framework for atmospheric modeling.

Scientific breakthroughs in understanding the climate system and resolving the uncertainties in the climate’s response to anthropogenic activities is contingent on the availability of robust atmospheric models with a broad range of capabilities. In response to that need, SIMA, or the System for Integrated Modeling of the Atmosphere, is an effort initiated by NCAR to develop a unified atmospheric modeling framework for the broad scientific community. The goal is for SIMA to enable scientific applications within and across climate, weather, chemistry, and geospace. This workshop aims to bring experts within and across these fields together to inform the scientific and technical directions for SIMA’s short- and long-term development.

We would be delighted if you, as an active developer, user, or manager of atmospheric models, could apply to participate in this workshop to provide feedback and direction to NCAR and the community on this next-generation effort. Below, you will find a draft agenda for the workshop, which will primarily consist of plenary sessions and breakout groups. The breakout groups will discuss various scientific facets of SIMA. There will also be some pre-recorded presentations, available prior to the workshop, for participants to review at their own time. Similar to a scientific meeting or conference, there will be opportunities to network with fellow participants and learn more about their current adventures in atmospheric modeling.

Because of the difficulties of holding a virtual meeting with many participants, we need to limit the overall number to a maximum of approximately 150. To apply to participate in this workshop, complete your application here:

If your application is accepted, you will commit to:
  1. Attempt to attend all planned sessions; time commitment ~10 hours total
    1. June 29th: 10 am to 12 pm (plenary) and 1 to 3 pm (breakout #1)
    2. June 30th: 10am to 12 pm (breakout #2) and 1 to 3 pm (breakout #3)
    3. July 1st: 10 am to 12 pm (synthesis)
    Note that all times are MDT.
  2. Review SIMA-related documents and videos that will be shared two weeks prior to the workshop; time commitment ~2 hours total
  3. Participate in two surveys at least 1 week before the workshop; time commitment ~15 mins each
    1. SIMA Community Survey:
    2. Atmospheric Model User Experience Survey:
If you have any questions about SIMA, the workshop, or your participation, please do not hesitate to email the SIMA leads: Andrew Gettleman (climate;, Bill Skamarock (weather;, Mary Barth (chemistry;, and Hanli Liu (geospace;
