SPARC-DA workshop

This page provides information regarding the SPARC-DA workshop (25-27 Oct. 2017). For information about the S-RIP workshop, click here.

For SPARC-DA workshop, while contributions from **all aspects** of middle atmosphere (chemical and dynamical) data assimilation are sought (as in previous years), a few key areas will be highlighted. This year, the following experts have been invited to broaden our understanding of the true atmospheric system, highlight issues with assimilated products and help focus discussions in these areas:

  • Development of new observing systems for the middle atmosphere and Observing System Simulation Experiment (OSSE) – Nathaniel Livesey (Jet Propulsion Laboratory, California Institute of Technology, USA)
  • Stratospheric DA in support of assessing trends in the state of the Upper Troposphere Lower Stratosphere (UTLS) – Mark Olsen (NASA, USA) and Peter Hoor (during the joint session, Johannes Gutenberg University, Mainz, Germany)
  • New DA techniques and applications for stratospheric data sets – Patrick Laloyaux (ECMWF, UK)
  • SPARC Activity Updates – Neil Harris (SPARC co-chair, University of Oxford, UK) and representatives of the following activities: Atmospheric Temperature Changes, ACAM, CCMi, DynVar, Gravity Waves, HEPPA/SOLARIS, LOTUS, OCTAVE-UTLS, QBOi and SNAP
  • Joint session with S-RIP – Peter Hoor (Johannes Gutenberg University, Mainz, Germany), Adrian Simmons (ECMWF, UK) and the representatives from NCEP, NASA, ECMWF and JMA reanalyses

This year, we will also have a discussion on the future of SPARC-DA. Recently, the SPARC Office requested that SPARC-DA prepare an implementation plan of our working group's activities and deliverables. We have agreed that SPARC-DA progress will be evaluated every four years. During this discussion, we will present the implementation plan and identify themes for the upcoming years. We expect that the SPARC Activity Update presentations will be helpful in shaping the discussion.

Due to budget cuts at WCRP, SPARC-DA received very limited funding for this workshop. As last year, it will be used preferentially for travel support for early career scientists and scientists from developing countries. Application for travel support should be submitted via the registration page before June 30, 2017.
