TPOS October 2015 Monthly Status Report (MSR)

Summary

The TPOS 2020 Steering Committee (SC) Co-Chairs conducted the second meeting of the SC (SC-2) on 14-17 October at CSIRO in Hobart, Australia. All SC members with the exception of Dake Chen were able to participate, with Harry Hendon and Weidong Yu joined remotely. They also welcomed the non-SC Task Team (TT) Co-Chairs, all of whom are able to participate (Eric Guilyardi joined remotely for the M&DA TT session only). They also welcomed a number of key stakeholders, from NOAA, NASA, IMOS and CSIRO, and a number of observers who joined for parts of the meeting. (The SC-2 Report will be released in late November/early December.)

The session reported that progress was made on all SC-1 Actions. TPOS 2020 appreciates the contributions of CSIRO, IMOS, and IMAS for hosting and their support of the meeting. In addition generous travel support for the meeting was provided by NOAA, NASA and the Intergovernmental Oceanographic Commission (IOC).

The SC-2 meeting was able to make significant progress across most aspects of the Project. It was noted that the level of scientific engagement is strong, though not uniformly high around the sponsors. Major outcomes were:

  • A community survey, which revealed a strong interest in TPOS 2020 work and provided guidance across the broad scope of TPOS 2020 work.
  • Potential to strengthen engagement and participation through its various Task Teams (e.g. Planetary Boundary Layer and Eastern Pacific Task Teams).
  • The “strawman” approach to developing initial ideas has worked well and led to options for reshaping the backbone as well as a number of proposals for supporting studies.
  • The Steering Committee decided to further elaborate four of the strawman :
      (a) Joint study with Years of the Maritime Continent,
      (b) The Diurnal Cycle (multiple time scales),
      (c) Equatorial Pacific upwelling and mixing physics, and
      (d) Double ITCZ process study.
  • Options for a redesign of the Tropical Pacific Observing System Backbone were presented and the methodology for determining priorities discussed. Further advice is being sought around a number of aspects including surface stress and possible extensions for surface variables. This interim design will undergo refinement and scientific and external review over the coming 12 months prior to publication.
  • Further consideration was given to priorities for modelling and data assimilation, integration of satellite contributions into the design, biogeochemical science questions and strategy for the Western Pacific.
