Scientists at the Global Modeling and Assimilation Office (GMAO) at NASA Goddard Space Flight Center
are investigating the assimilation of Global Precipitation Mission (GPM) Microwave Imager (GMI) radiance measurements. Current efforts are
expanding the all-sky (clear, cloudy, and precipitating) data assimilation methodology under development in the GSI system while also
determining how the system is reacting to the assimilation of only clear-sky observations. The ultimate goal is to routinely assimilate
these data to improve weather forecasts including severe storms and hurricanes as well as to improve global cloud and precipitation analyses.
The JCSDA is calling for proposals for scientific projects in a variety
of areas related to satellite data assimilation, including cloudy/rainy
radiance data assimilation, optimization of satellite data assimilation,
and improvement of the Community Radiative Transfer Model (CRTM). The potential
of the proposed effort to improve the U.S. operational system's forecasts skill
will be key in evaluating proposals. Applicants are encouraged to
submit letters of intent. For more information, see the full
Federal Funding Opportunity (FFO).

HAMKARI - the largest/most decisive surge to date. While there, he was hand-picked to lead the Secretary
of Defense's $850M Persistent Surveillance Systems Operation ENDURING FREEDOM deployment.
Previously, as the Commander of the 607th Weather Squadron in the Republic of Korea, he led combined weather
operations during north Korea nuclear and missile tests/crises. As executive officer to the PACAF Director
of Operations, he led support for tsunami-ravaged Indonesia and south Asia.
Finally, as Director of Operations for the 17th Operational Weather Squadron he led the unit to full
operational capability while supporting vital Operations IRAQI and ENDURING FREEDOM missions, presidential
and Secretary of Defense support, typhoon evacuation, as well as intelligence, surveillance and
reconnaissance mission support across the entire Pacific Command.
Nick joined the Navy as a Special Duty Oceanography Officer
in 1994 after graduating from Texas A&M University at Galveston with a B.S. in Marine Science.
After tours of duty at the Naval Oceanographic Office at Stennis Space Center, MS and at the Naval
Atlantic Meteorology and Oceanography Facility in Jacksonville, FL, Nick earned his M.S. in
Meteorology and Physical Oceanography in 2003 and his Ph.D. in Meteorology, in 2006, from the Naval
Postgraduate School. During his graduate work, he specialized in aerosol optical depth retrievals
from high resolution commercial satellite imagery. After graduate school, Nick served as the Ship's
Meteorologist aboard the aircraft carrier USS GEORGE WASHINGTON, as well as tours back at Stennis
Space Center with the Fleet Survey Team and on the staff of the Commander, Naval Meteorology and
Oceanography Command. Following staff duty, Nick served as Commanding Officer of the Naval
Oceanography Antisubmarine Warfare Center in Yokosuka, Japan, providing oceanographic support to
Navy ship in the Western Pacific, as well as weather support coordination for Commander, Naval
Forces Japan. In 2013, Nick reported to the Office of the Oceanographer of the Navy as the Deputy
Technical Director and was appointed to the JCSDA Management Oversight Board, and, most recently,
relieved Dr. Bob Atlas as the Chairman of the Management Oversight Board in June 2014.
The Air Force Weather Agency (AFWA) has been utilizing the Weather
Research & Forecasting (WRF) model as its numerical weather prediction model of choice since 2007.
From the first operational WRF model run, AFWA has employed the three-dimensional variational analysis (3DVAR)
data assimilation (DA) system developed at the National Center for Atmospheric Research (NCAR) to produce the
initial conditions for the forecast model. In 2012, AFWA began preparing its infrastructure to transition its DA
system to the Gridpoint Statistical Interpolation (GSI) DA system developed at the National Centers for
Environmental Prediction (NCEP) and used operationally in their suite of models. AFWA's Initial Operational
Capability (IOC) was met when the first operational domain began using GSI in July 2013. By the end of 2013,
all of AFWA's regional modeling efforts had transitioned to GSI.
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.
Dr. 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.
