About Us
The HYCOM consortium is a multi-institutional effort funded by
the National Ocean Partnership Program (NOPP),
as part of the U. S. Global Ocean Data Assimilation Experiment (GODAE),
to develop and
evaluate a data-assimilative hybrid isopycnal-sigma-pressure
(generalized) coordinate ocean model (called HYbrid Coordinate
Ocean Model or HYCOM).
Welcome to The HYbrid Coordinate Ocean Model Home Page
HYCOM Consortium Data Servers
http://www.hycom.org/dataserver/
Hycom Consortium data products are available online from our servers.
The data can be accessed via the Live Access Server(LAS) or the
Distributed Oceanographic Data System (DODS). A data catalog is
available to query the datasets currently online. Additional data
can be made online by making a request.

Global Scale Simulations
The emphasis is on long integrations (with a coarse mesh size, usually
more than 1°) to evaluate the model's response on decadal to
centennial time scales (water mass formation, mixed layer physics,...).
Basin Scale Simulations
The emphasis is on short integrations with high resolution [with a fine
mesh size. i.e., eddy-permitting (1/3°) or eddy-resolving (1/12°
)] to evaluate the model's response on seasonal to decadal
time scales (eddy activity, mode water formation, ...).
Regional/Coastal Studies
The emphasis is on short integrations with high resolution to evaluate
the model's behavior in coastal regions.

Process Studies
The emphasis is on idealized configurations that investigate either a
specific physical process or the numerical performance of HYCOM.
Data Assimilation Techniques
A hierarchy of data assimilation techniques are evaluated as a function
of computational resources and prediction accuracy:
- the Optimal Interpolation (OI)
- the Parameter Matrix Objective Analysis algorithm (PMOA)
- the Reduced Order Adaptive Filter (ROAF)
- the Reduced Order Information Filter (ROIF)
Reanalysis
Assimilation of temperature and salinity profiles in HYCOM to
reconstruct the ocean state of the past decades.

Education and Community Outreach
Making model output available to:
- the members of our consortium for HYCOM and data assimilation
code development;
- the wider oceanographic and scientific communities, including
climate and ocean ecosystem researchers;
- students in elementary and high school education, to more widely
disseminate our research, and to encourage students to consider
careers in science and engineering.

Ocean Surface Currents
Our web-based ocean current reference site contains
information on surface currents in the Atlantic Ocean.
Each current has important links, summary text detailing
velocity and hydrographic observations, and plots such as,
average current speed and locations, drifting buoy positions,
sea surface temperature maps, and HYCOM simulations.
