Participants at JCSDA 11th Annual Science Workshop.

Participants at JCSDA 11th Annual Science Workshop.

About 70 scientists from the Joint Center and its academic and private sector partners, including principal investigators, program managers and JCSDA management/staff, participated in the 11th Annual JCSDA Workshop on Satellite Data Assimilation, June 5-7, 2013, at NOAA's Center for Weather and Climate Prediction on the research campus of the University of Maryland in College Park.

The Workshop was opened by greetings from representatives of the JCSDA's Management Oversight Board. Simon Chang, Naval Research Laboratory, pointed out that there is much work to be done, no one agency can do it, and the Joint Center was needed to facilitate progress. Colonel Daniel Edwards, USAF, highlighted the DoD's analysis of alternatives for a follow-on to the terminating Defense Meteorological Satellite Program, and the need for the Joint Center to quantify the benefits of proposed alternatives. Bill Lapenta, NOAA/National Weather Service (NWS), expressed appreciation for the Center's contributions to improving forecast model guidance and urged investigators to focus on how their work can be integrated into operations. Stan Benjamin, NOAA/Oceanic and Atmospheric Research (OAR), lauded the Center for its assistance in making the Gridpoint Statistical Interpolation assimilation system into a truly community model.

In the first session of the workshop, JCSDA Director Riishojgaard presented a status report and overview of the Center's activities. Major accomplishments at the JCSDA partner agencies included:

  • NOAA/National Centers for Environmental Prediction's implementation of a new hybrid data assimilation system, which resulted in a significant increase in prediction accuracy, allowing the GFS to catch up with the UKMO in forecast skill

  • NASA/Global Modeling and Assimilation Office's update of its observation impact software to include the effect of moist processes in the adjoint, which allows more realistic evaluations of the impact of moisture observations

  • NOAA/OAR's experiments showing the positive impact of assimilating AIRS observations in the Rapid Refresh mesoscale model and its short range forecasts

  • Naval Research Laboratory's improvement and syncing of its Atmospheric Variational Data Assimilation System (NAVDAS-AR) with the new Navy Global Environmental Model (NAVGEM), which replaced its NOGAPS model

  • The Air Force Weather Agency's significant progress in transitioning of the Gridpoint Statistical Interpolation assimilation system to its operational mesoscale forecast models.

Focusing on topics related to the Center's scientific priority areas, the workshop's 32 oral and 22 poster papers covered: Radiative Transfer Modeling and Validation, Assimilation of Data from Advanced Sensors, Cloud and Precipitation Data Assimilation, Land Data Assimilation, Ocean Data Assimilation, Regional Data Assimilation, Observing System Simulation Experiments and Observing System Experiments (data denial studies), and Atmospheric Composition. In the final plenary, the audience, guided by the Center's Executive Team, participated in an open discussion of scientific and programmatic issues raised at the workshop.

The purpose of these annual workshops is to review the ongoing and planned scientific development sponsored by the Center, and to coordinate these efforts. The Joint Center supports scientific development work with internally directed funds as well as with external grants and contracts awarded via a competitive process open to the broader scientific community. In addition, JCSDA individual partners undertake their own research contributing to the Center's objectives.
