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

The annual JCSDA technical review meeting and science workshop was 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 were 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.

Dr. Nancy L. Baker Named Associate Director for Navy for the JCSDA

Nancy BakerDr. Baker joined the Naval Research Laboratory (NRL) Marine Meteorology Division (MMD) in Monterey, CA in 1985 and has been Data Assimilation Section Head since 2004. Dr. Baker received her B.S. in Atmospheric Sciences from Oregon State University in 1981, her M.S. in Atmospheric Sciences from the University of Washington in 1985 and her Ph.D. in Meteorology from the Naval Postgraduate School in 2000. Dr. Baker is an internationally recognized expert in the assimilation of atmospheric data into Numerical Weather Prediction (NWP) models. Her specialties are very broad, and include many aspects of data assimilation; including both 3D and 4DVar, and hybrid ensemble-variational assimilation. As head of the Data Assimilation Section, she led NRL's program to develop, implement, and refine the Navy's operational data assimilation systems NAVDAS, NAVDAS-AR and COAMPS-AR. The adjoint-based observational impact technique she co-developed has been adopted at several NWP centers. She led the Division's efforts to assimilate various satellite sensor observations, such as AMSU-A, SSMIS, MHS, IASI, AIRS, GNSS, MODIS AOD, and WindSat, into Navy operational DA systems. Recently, her group successfully developed the capability for the Navy to assimilate NPP SUOMI data.

Dr. Baker has served as a member of the American Meteorological Society Committee on "Satellite Meteorology and Oceanography," and as a committee member for National Academy Panel "NOAA's Role in Space-Based Global Precipitation Estimation and Application." She has served as a research advisor for both the National Research Council and the American Society for Engineering Education (ASEE). She has been a Technical liaison for the Navy to the Joint Center for Satellite Data Assimilation since 2002.


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.

A Near Real-Time Regional Satellite Data Assimilation System for High Impact Weather Research and Forecasts

Under the NOAA JPSS, GOES-R and JCSDA support, scientists from the Cooperative Institute of Meteorological Satellite Studies (CIMSS) at the University of Wisconsin-Madison have recently developed a near real time (NRT) regional Satellite Data Assimilation system for Tropical storm forecasts (SDAT). The purpose of SDAT is primarily to demonstrate the use of JPSS and GOES-R observations toward forecast improvement of these high impact weather events.

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.
