The NOAA Operational Model Archive and Distribution System

Project Description
To address a growing need for remote access to high volume
numerical weather prediction and global climate models and
data, the National Climatic Data Center (NCDC), along with the
National Centers for Environmental Prediction (NCEP) and the
Geophysical Fluid Dynamics Laboratory (GFDL), initiated the
NOAA Operational Model Archive and Distribution System (NOMADS)
project. The NOMADS framework was developed to facilitate
climate model and observational data inter-comparison issues as
discussed in documents such as the Intergovernmental Panel on
Climate Change (IPCC 1990, 1995, 2001) and the U.S. National
Assessment (2000). NOMADS is being developed as a Unified
Climate and Weather Archive to provide Web access to model
information so that users can make decisions about their
specific needs. This on time scales from days (weather), to
months (El Nino), to decades (global warming). NOMADS also
addresses model data access needs as outlined in the
U.S. Weather Research Program (U! SWRP) Implementation Plan
for Research in Quantitative Precipitation Forecasting and Data
Assimilation to "redeem practical value of research findings
and facilitate their transfer into operations." For more
information see: The NOMADS Program Overview.

NOMADS is a network of data servers using established and
emerging technologies to access and integrate model and other
data stored in geographically distributed repositories in
heterogeneous formats. NOMADS enables the sharing and
inter-comparing of model results and is a major collaborative
effort, spanning multiple Government agencies and academic
institutions. The data available under the NOMADS framework
include model input and Numerical Weather Prediction (NWP)
gridded output models from NCEP; and Global Climate Models
(GCM) and simulations from GFDL and other leading institutions
from around the world. The goals of NOMADS are to:

1.Improve access to NWP and GCM's datasets.

2.Improve the linkages between the research and operational
modeling communities.

3.Foster collaborations between the climate and weather
communities. Provide the observational data and model analysis
initialization products for regional models.

4.Improve the verification process of forecast and climate
models. Promote product development and collaborations within
the geo-science communities (ocean, weather, and climate).

5.Provides cost effective pull technologies for "hyper-slabs"
of high volume data sets.
