The 12th JCSDA Technical Review Meeting & Science Workshop on Satellite Data Assimilation

The annual JCSDA technical review meeting and science workshop is to be held at the National Center for Weather and Climate Prediction in College Park, MD on May 21-23, 2014. Two full and one half days will be devoted to the meeting with plenty of time for discussions, interactions, scientific exchanges, and formal presentations, both among scientists from all JCSDA partners and with JCSDA managers. Formal recommendations from working-group discussions that take place during the meeting are reviewed by the JCSDA management on an annual basis, and serve as one of the inputs when developing technical directions of the JCSDA future activities. For more information about the workshop and how to register, please visit the 12th JCSDA Science Workshop webpage.


Satellite Data Assimilation Updates in Navy's New Global Prediction System

The Navy's high-resolution global weather prediction system, run operationally at the Fleet Numerical Meteorological and Oceanographic Center (FNMOC), is the critical component of the Navy's atmospheric prediction capabilities, providing 180-hour forecasts every six hours and 16-day guidance twice-daily using a 20 member global ensemble. On February 13, 2013 a significant milestone in the U.S. Navy's weather forecast system development was achieved as the Navy Global Environmental Model (NAVGEM) replaced the Navy Operational Global Atmospheric Prediction System (NOGAPS) for operational global weather prediction (Hogan et al. 2013). This new operational system, NAVGEM 1.1, combines a semi-Lagrangian/semi- implicit dynamical core with advanced physical parameterization schemes for moisture, convection, ozone, and radiation.


Summary of 11th JCSDA Workshop on Satellite Data Assimilation

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.


Second Symposium on the Joint Center for Satellite Data Assimilation

The Joint Center has agreed with the American Meteorological Society to arrange a "Second Symposium on the Joint Center for Satellite Data Assimilation" as part of the "10th Annual Symposium on New Generation Operational Environmental Satellite Systems" during the 2014 AMS Annual Meeting in Atlanta.

The JCSDA Symposium will take place on Thursday, February 6, and this year the primary focus will be on the scientific and technical activities of JCSDA and its partners. In particular we solicit contributions in the following areas:


Gridpoint Statistical Interpolation Assimilation System: 2013 Tutorial and Workshop
GSI Tutorial Workshop 2013

The 2013 Joint Developmental Testbed Center (DTC) - Environmental Modeling Center (EMC) - JCSDA Community Gridpoint Statistical Interpolation (GSI) Tutorial and GSI Workshop will be held at the National Oceanic and Atmospheric Administration (NOAA) Center for Weather and Climate Prediction (NCWCP), College Park, Maryland, August 5-8. GSI is a variational data assimilation system used in a variety of forecast models, including the Global Forecast System, North American Mesoscale model, Real-Time Mesoscale Analysis, Hurricane Weather Research and Forecasting model, and NASA?s Goddard Earth Observing System model. It is also a community model used by a number of research groups.

The GSI Tutorial will be held on August 5-7, 2013, and includes both lectures and hands-on practical sessions. The Tutorial is designed to train participants in the use of the GSI: how to run and develop the system. The invited speakers are from the primary GSI development teams, including the data assimilation experts working at and with NOAA/EMC, NOAA/Earth System Research Laboratory, JCSDA, NASA/Global Modeling and Assimilation Office, National Center for Atmospheric Research, and the DTC.
