The 9th JCSDA Science Workshop on Satellite Data Assimilation will be hosted by the College of Computer, Mathematical and Natural Sciences (CMNS) of the University of Maryland, College Park. The main conference room (#2324) is locatd in the Computer & Spaces Science Building on the 2nd Floor. This location offers convenient access to the Metro public transit system of the Washington, DC area (College Park/Univ. of MD Metro station, and the Metro bus). It is also walking distance from downtown College Park, MD.

Buildings on the University of Maryland College Park campus do not have street numbers. So, to get directions to College Park via online map or your car's GPS, you should input the university's basic street address:
7950 Baltimore Avenue, College Park, MD


Registration for the Workshop is now closed. Please contact Dr. Sid Boukabara to request late registration.

Shuttle from the College Park Metro station:

The University of Maryland, College Park, runs a wide network of shuttles for students and staff in and around College Park, MD and is allowing participants of the workshop to use the shuttle from the College Park Metro station. The number 104 shuttle that the participants may use runs every 10 to 15 minutes from 6:00am to 3:00am (~10 minute ride). See shuttle schedule for complete details.


There are many options for lunch around the main campus in College Park, but one convenient alternative is the University of Maryland food court at the Adele H. Student Union building, not far from the workshop conference room. It offers many options ranging from fast food, coffee shops, to sit-down restaurants. For more information, please see this list of dining and lodging listings for College Park.

Parking Information:

Workshop participants can choose lodging options that are walking distance from the conference room or use public transportation (Metro station College Park, University of Maryland), from Washington, DC downtown for instance. If using a car, there are a number of visitor parking lots in and around the University main campus.


There are many hotels within walking distance to the main campus for those who prefer to stay around the meeting location. College Park metro station is on the Metro green line: A fifteen (15) minutes Metro ride to downtown Washington, DC. So participants can also chose to stay in downtown Washington DC. We are currently working with the University of Maryland to allow workshop participants to use the UMD shuttle to go from the College Park Metro station to the main campus. The location of the meeting is about 30 minutes walking distance from the College Park Metro station.

Workshop Purpose

The purpose of the JCSDA Science Workshop is to review the ongoing and planned scientific development sponsored by the NASA-NOAA-DOD Joint Center for Satellite Data Assimilation (JCSDA), and to plan and coordinate future efforts. The JCSDA has six scientific priority areas:

  • Radiative transfer

  • Clouds and precipitation

  • Advanced instruments

  • Land data assimilation

  • Ocean data assimilation

  • Air Composition

The JCSDA supports scientific development work in these areas with proposal-based, internally directed funds as well as with external grants and contracts awarded via a competitive process open to the broader scientific community. In fiscal year 2010, this competitive process took the form of a federally funded opportunity (FFO) led by NOAA. In fiscal year 2011, this process took the form of a NASA announcement within the Roses 2010 opportunity. In addition, JCSDA individual partners undertake their own research that overlaps with JCSDA objectives. It is essential that all these efforts be complementary and coordinated. The JCSDA science workshop aims at facilitating this coordination. At the JCSDA Science Workshop, JCSDA Principal Investigators and affiliated scientists are expected to report on progress and participate in discussions about the progress and future plans of the Joint Center.

Organization of the Workshop:

The JCSDA science workshop on satellite data assimilation will have both oral presentations (all in a single plenary session) and posters. In order to allow for open discussions, plenty of time will be made available to presenters to interact with the audience. Adequate visibility will be provided to both management-level presentations from the JCSDA partners and to contributed scientific material in all scientific areas. Management-level presentations will provide a context in which the scientific effort fits. They also offer an opportunity for scientists to ask questions about the future plans and the scientific directions being considered. There will be break-out sessions, limited to group discussions of the plans and progress for the six science priority areas. It is expected that general and scientific recommendations be made following this breakout session and be presented at the final plenary session. There will also be a dedicated posters session. Note that posters will be mounted on their panels the first morning of the workshop and will remain mounted until the end of the workshop. This will allow scientists to interact on the content of the posters not only at the posters session but also during coffee breaks and lunch breaks if desired. A Software Packages and Science Integration session is also scheduled the second day of the workshop, to highlight a number of software packages and tools that are available to scientists and to show interested parties how to get access to these JCSDA resources (supercomputer, visualization tools, scientific software packages, formatting tools). This is expected to provide JCSDA- affiliated scientists the necessary environment to pre-test the impact of their efforts on operational assimilation models, and to assess their impacts on different forecast skills.
