WGNE-30 Header Image

Welcome to the 30th annual meeting of the World Meteorological Organization's Working Group for Numerical Experimentation (WGNE), co-sponsored by the World Climate Research Program (WCRP) and the World Meteorological Organization Commission for Atmospheric Sciences (CAS).

The WGNE, jointly established by the WCRP Joint Scientific Committee (JSC) and the CAS, which is responsible for the World Weather Research Programme (WWRP) and the Global Atmosphere Watch Programme (GAW), has the responsibility of fostering the development of atmospheric circulation models for use in weather, climate, water and environmental prediction on all time scales and diagnosing and resolving shortcomings (WMO/TD 121). WCRP-JSC/CAS WGNE promotes co-ordinated numerical experimentation for validating model results, observed atmospheric properties, exploring the natural and forced variability and predictability of the atmosphere, (e.g. the Atmospheric Model Intercomparison Project, AMIP), as well as studies aimed at refining numerical techniques, and the formulation of atmospheric physics processes. WGNE also monitors advances in data assimilation and analysis methods and is the focal point in the WCRP for encouraging and reviewing the reanalysis projects carried out at various centers with fixed state-of-the-art assimilation systems providing a multi-year homogenous data set for a range of atmospheric and climate diagnostic studies.

The NOAA Center for Weather and Climate Prediction (NCWCP) resides on a 10-acre section of the University of Maryland's Research and Technology Park, known as "M-SQUARE".

The state-of-the-art NCWCP building consolidates several NOAA organizations including:

  • The National Centers for Environmental Prediction (NCEP)
  • The National Environmental Satellite, Data, and Information Service (NESDIS), Office of Research and Applications and Satellite Services Division
  • The Office of Oceanic and Atmospheric Research (OAR), Air Resources Laboratory

At the entrance of the NCWCP building is the Conference Center. It is outside of the security section, and accessible without a clearance. For those wishing to visit anyone inside the security section, a permit will have to be arranged ahead of time.

Please note that security clearances cannot be arranged during the conference.
If you wish to arrange a visit, please contact Dr. Michael Ek as soon as possible.

The Conference Center consists of an Auditorium and several break-out rooms. All are equipped with the typical audio-visual capability from a Windows workstation. Note that presenters will not be able to hook up their own laptop to the audio-visual screen. Free open-access WiFi will be available in the auditorium and conference break-out rooms.

There is free on-site parking for conference members.

If you require a visa, please contact your local U.S. embassy or consulate for information about current visa processing time estimates and processes. For information on US embassies, consulates, and diplomatic missions, visit USEmbassy.gov. It is important to apply as early as possible – visa applications should be submitted several months in advance of anticipated travel. If you have any questions, please feel free to contact us.

The WGNE-30 meeting is outside of NCWCP building security, but if you wish to visit our office (inside security), please contact Dr. Michael Ek as soon as possible, and we will work on obtaining the necessary permission (this is handled individually).

College Park, MD 20740

Main Phone: (301) 683-1314

Note: Sometimes the address comes up as "Riverdale" instead of "College Park"

Detailed directions to the NCWCP are available here (PDF).

Shuttle from/to Greenbelt Marriot Hotel:

In the morning, a shuttle bus will leave the hotel at 7:30 and another at 7:50, arriving at NCWCP in 10-15 minutes. In the evening, two shuttles will return to the hotel at 15 and 35 minutes after the meeting ends for the day, although this is flexible. Please bring picture identification, such as a passport, to present at the guard house --no special permission is required to then proceed to the conference center.

Nearest Metrorail station:
College Park Metro Station (Green Line)

The Metro station is just over half a mile (1 km) away from the NCWCP. Instead of walking around on River Road to University Research Court, there is a slightly shorter walking path that can be taken (the dashed yellow line):

walking path

There is the "River Road-109 Shuttle" that runs from the College Park Metro station to our building year-round, Monday through Friday except on Federal Holidays. It runs every 15 minutes from 6:00 until 9:00 AM and again from 3:00 until 6:00 PM.
