associated infrastructure (the Flexible Modeling
System) developed at GFDL to CDC. The development
effort will be aimed at getting the model up and
running in parallel on a Beowulf cluster. We
anticipate some amount of back and forth with GFDL as
we try to get the model to run in a new environment,
but this activity will be useful to other NOAA labs and
to the academic community.
We have had an active development project for almost a year but have not used any resources, since GFDL has not been able to produce a model that compiles on Intel platforms. Once they've produced such a model we should be able to accomplish our goals fairly quickly. Researchers in CDC and elsewhere will apply separately for resources to do production runs. | Authorized Users: | Robert Pincus | Cecile Hannay | | | | | | | | | | | | | | | | | | Top |

example, such models are used in international

project is a simulation study to compare several forms
of stock-population model on a wide variety of

weather and climatic extremes may be more damaging and
that air quality will deteriorate. The objective of
this project is to provide credible information on
regional climatic and air quality, including their
variability, change and impact, as a scientific basis
for decision makers to select optimal pathways to
achieve future economic, societal and environmental
goals, for example in the mid-Atlantic region. In
collaboration with the Illinois State Water Survey/UIUC
the PSU/NCAR MM5 model has been modified to incorporate
the physical parameterizations essential for climatic
simulations, especially those of NCAR CCM4-embedded
cloud-radiation and surface-air interactions. The
system will be adapted to the WRF model once it is
released. The air quality model is based on recently
improved version of the Models-3(EPA), i.e.,
SAQM(SUNYA). Our tasks are 1) to downscale GCM climate
simulations, such as from CCM3 and NCEP models, and
compare to observations on regional scale for
variability and extremes; 2) to simulate the surface
ozone and particle levels within the domain, a forecast
and data assimilation capability for air quality
parameters will be developed; and 3) based on 1) and
2), to perform scenario experiments to study potential
impacts to changing climate and air quality on regional

| | Climate and Role of the Thermohaline Circulation | (CROTC) | | Principal Investigator: | Sang-Ik Shin | E-mail: | Sangik.Shin@noaa.gov | Organization: | Climate Diagnostics Center | Project Type: | Non-FSL | Project Description: | We propose to investigate the role played by the
oceanic thermohaline circulation (THC) in natural
climate variablility. The paleoclimate record shows
indications of changes in the rate of North Atlantic
Deep Water (NADW) formation accompanying rapid climate
transitions, with weaker overturning usually associated
with colder periods, and stronger overturning being
related to warmer periods. However, the effect of
large THC variations of the global climate is still
unclear. Numerical model simulations seem to yield
contrasting results, and the processes that may be
responsible for far-field effects of overturning
variability have not been fully explored. We will use
a state-of-the-art coupled climate system model, the
National Center for Atmospheric Research Community
Climate System Model version 2 (NCAR CCSM2), to assess
the possible large scale impact of significant
variations in the strength of the meridional
overturning, to examine phase relationships among
changes occurring at different locations or among
different components of the climate system, and to
identify the physical processes responsible for the
large-scale pattern of variablility that may be
important in the understanding, attribution, and
prediction of future climate change. To investigate the
role of the oceanic THC in natural climate variability,
we propose 1,000 year fully coupled model simulation,
which encompass the full overturning cycle in the
ocean. It is known that the timescale of the oceanic
thermohaline circulation is about several hundred to a
thousand years. By completing a 1,000 year simulation,
we anticipate several referred journal articles from
the proposed project. Besides our interest, the
proposed simulation will produce benchmarking data,
which can be used in various climate variability
studies of timescales ranging from seasonal to millennial. | Authorized Users: | Sank-Ik Shin | Prashant Sardeshmukh | Robert Webb | | | Joseph Barsugli | | | | | | | | | | | | | | Top |

jointly by researchers at Rutgers University and UCLA.
ROMS is a three-dimensional primitive equation ocean
circulation model, implemented on a curvilinear-orthogonal grid with a s-coordinate in the vertical (for details, see
http://marine.rutgers.edu/po/model/roms.html).
FSL staff were instrumental in developing an SMS

North Pacific Ocean at 40 km resolution, run for
several model decades to provide boundary conditions to
the coastal-regional model; 2) The coastal -regional
circulation grid, which spans the North American west coast from Southern California to the Bering Sea with a 10 km resolution. Multi-year runs are executed for regional analyses, and to provide boundary conditions to local models; 3) Various local
grids at 2.5 km resolution, run with embedded lower trophic level (NPZ) biology (with emphasis on juvenile
salmon prey items), and used to provide prey fields for an individual-based salmon model. The fish models will be run on local computing platforms. An overview of work on related projects, including results from earlier coastal models, are available at our web sites

network. As such, an internal proposal has been
submitted to Sandy for completion of this work. I have
not heard a final decsision on it, but understand it
was viewed quite favorably.
Project details will be quite similar to those of the

1) Generation of the simulated observations will need
to redone (similir to the work that John Smart did
under the old lidaross project). This will require
that all the regional nature run files be resident on a
disk at one time, so the obs imulate can generate the
obs (these are the files that Lee Cohen helped me
locate on the mass store). There are 264 895 MB files,
so I am requesting 300 GB of disk space for the

models including QNH and WRF at 10 km resolution for
predictions of mesoscale weather and hurricane. A
non-structured type of global model, HGM, is also under
development. We anticipate the increase of disk space

Regional Atmosphere Modeling and Data Assimilation
System developed at CIRA. This system is designed to
investigate impact of direct satellite radiance
assimilation as well as assimilation of other remote
sensing (GPS, radar) and conventional observations into
the regional forecast model (RAMS) for advancements of
mesoscale data analysis and forecast. The emphasis
in this research is on explicit cloud analysis and
other mesoscale forecast initialization. The method of
assimilation is 4DVAR. RAMDAS is derived from the
NCEP's Eta 4DVAR data assimilation system but the RAMS
model and the associated adjoint are employed instead
of the Eta model. As part of the RAMDAS testing we
will implement the WRF observational transformation
operators and data base. An esemble equivalent of
RAMDAS will also be tested. | Authorized Users: | Milija Zupanski | Tomislava vukicevic | Dusanka Zupanski | | | | | | | | | | | | | | | | | Top |

analysis of the Northern Hemisphere lower and middle
tropospheric circulation extending back to the
beginning of the 20th century. Ther current NCEP/NCAR
reanalysis extends back to 1948, the beginning of the
radiosonde era. Using advanced ensemble-based data
assimilation techniques we have demostrated that, using
only surface pressure observations at 1915 densities, a
500 mb height analysis can be produced that is about as
accurate as a 3 day forecast is today. The development
of the parallel algorithm and the feasibility study
were produced using JET resources under the ENSPARA

| | Re-Forecasting with the MRF Ensemble | (REFCST) | | Principal Investigator: | Jeffrey Whitaker | E-mail: | Jeffrey.S.Whitaker@noaa.gov | Organization: | Climate Diagnostics Center | Project Type: | Non-FSL | Project Description: | The goal of this project is to create a 20+ year data
of ensemble forecasts with a fixed version of the
global MRF model. This dataset will be useful both for
predictability studies and for deriving statistical
corrections which will increase the skill of real-time
medium range forecasts. Existing archives of
operational ensemble forecasts suffer from two
problems; 1) they are short (5-6 years long), and 2)
they span many model changes that significantly affect
forecast error characteristics. 22 years of a single
MRF 21-day forecast, at T62 resolution, starting from
reanalysis initial conditions, has been completed
during the development phase of this project. The
focus will now be on running perturbed ensemble
members, using the so called "breeding" method to
generate initial perturbations. A total of 10
perturbed runs will be generated for a 22 year period. | Authorized Users: | Jeffrey Whitaker | Xue Wei | | | | | | | | | | | | | | | | | | Top |

impact from assimilating radial velocity observations
from a Doppler Wind Lidar (DWL) placed aboard a polar
orbiting satellite. Utilizing idealized DWL
observations obtained from a regional nature run
(created by A. Marroquin using MM5) and boundary
conditions from a global lidar OSSE (run at NCEP),
regional lidar OSSE experiments will be conducted using
the 20km CONUS version of the RUC model. These
experiments will consist of retrospective multi-day 1-h
cycled RUC model forecasts, run with and without the
lidar observations. Within FSL, a very high priority
has been placed on obtaining results from this lidar
OSSE experiment as soon as possible. | Authorized Users: | Steve Weygandt | Stan Benjamin | Georg Grell | | | Tracy Smith | Dezso Devenyi | | | | | | | | | | | | | Top |

Diagnostics Consortium. The boundary conditions for
these simulations are observed global sea surface
temperatures (SSTs), allowing us to isolate the forcing
due to these SSTs. Results from these simulations are
compared with those from other climate models and also
with observations. In addition, we will also produce
experimental seasonal forecasts using similar ensemble
methods in which we persist current global SST
anomalies forward into the next season. | Authorized Users: | Gary Bates | Taiyi Xu | | | | | | | | | | | | | | | | | | Top |

NOAA/OGP. The goal of the project is to go beyond
investigations of the predictability of the winter-mean
extratropical flow towards that of the synoptic
variability ("stormtracks"). We will use very large
ensemble (> 200 members) integrations of the
operational NCEP GFS model with specified boundary
conditions corresponding to seasonal and
decadally-averaged conditions to determine the
SST-forced signal of stormtrack variations. Very large
ensembles are needed to accurately estimate the
predictability of the stormtrack and associated
precipitation anomalies. A series of integrations at
differing horizontal and vertical resolutions will help
to determine the sensitivity of the results to these
model details. | Authorized Users: | Gilbert P. Compo | Prashant D. Sardeshmukh | | | | | | | | | | | | | | | | | | Top |

ability to generate a space weather climatology using
physical consistent data-driven space weather models.
In this proposal we will create a consistent,
integrated historical record of the near Earth space
environment by coupling observational data from space
environmental monitoring systems archived at NGDC with
data driven, physically based numerical models. The
resulting product is an enhanced look at the space
environment on consistent grids, time resolution,
coordinate systems and containing key fields allowing
a scientist/engineer to quickly and easily assess the
impact of the near-Earth space climate on
environmentally sensitive systems. Currently there
are no long term climate archives available for the
space-weather environment. Just as with terrestrial
weather it is crucial to understand both daily weather
forecasts as well as long term climate changes, so this
project will demonstrate the ability to generate a
meaningful and physically derived space weather
climatology. | Authorized Users: | Dr. Aaron Ridley | Dr. Mikhail Zhizhin | Eric Kihn | | | | | | | | | | | | | | | | | Top |
