ARTICLE I - SCOPE
This Implementing Arrangement describes the
cooperative scientific, technical, engineering and
administrative activities to be undertaken by the
American Institute in Taiwan (AIT) and its
designated representative, the University
Corporation for Atmospheric Research (UCAR), to
provide consultancy services for the Operational
Implementation of the WRF 3D-Var System and the
Assimilation of GPS Radio Occultation Data for
Typhoon Prediction. This is a cooperative effort
between the Taipei Economic and Cultural
Representative Office in the United States (TECRO),
through its designated representative, the Central
Weather Bureau (CWB), of the Ministry of
Transportation and Communications (MOTC) and AIT,
through its designated representative, UCAR. This
Implementing Arrangement pertains to the Agreement
(dated January 12, 2005, hereinafter referred to as
the Agreement) between TECRO and AIT for Technical
Cooperation associated with the establishment of
advanced data assimilation and modeling systems and
is a part of the Agreement.

ARTICLE II - AUTHORIZATION
The activities described in this Implementing
Arrangement will be carried out under the general
terms and conditions established by the Agreement.
The Agreement was entered into by the parties
pursuant to the Taiwan Relations Act of April 10,
1979, Public Law 96-8 (22 USC 3301 et seq.).

ARTICLE III - SERVICES
The FORMOSAT-3/COSMIC (Formosa Satellite Mission
#3/Constellation Observing System for Meteorology,
Ionosphere and Climate) is a joint satellite
mission between Taiwan and United States (U.S.),
with a goal to demonstrate the use of GPS RO data
in operational weather prediction, climate
analysis, and space weather forecasting.
FORMOSAT-3/COSMIC will launch six LEO satellites
in late 2005. The FORMOSAT-3/COSMIC is expected to
produce ~2,500 GPS RO soundings per day uniformly
distributed around the globe. The
FORMOSAT-3/COSMIC data will be available in
near-real-time (within 2 hrs. of observations) to
support the use of GPS RO data in operational
numerical weather prediction. Taiwan is extremely
vulnerable to the passage of tropical cyclones
(TCs). In a typical year, three to four typhoons
have an impact on the island, with one or two
making landfall. However, a typhoon does not need
to make direct landfall for Taiwan to experience
damaging winds and heavy rains. The forecasting of
typhoons around Taiwan is a very challenging task,
because Taiwan is surrounded by ocean, where there
are few traditional meteorological observations.
TECRO's designated representative, CWB, will be
provided software and consulting services for the
implementation of an advanced data assimilation
system (e.g., WRF 3D-Var) into CWB's operational
environment by AIT's designated representative,
UCAR. AIT's designated representative, UCAR, will
perform assimilation of GPS RO data and assess the
impact of the GPS RO data on typhoon prediction,
in close collaboration with TECRO's designated
representative, CWB. The technical cooperation and
technology transfer between the designated
representatives of TECRO and AIT will be performed
in accordance with the terms and conditions of the
Agreement, this Implementing Arrangement, and
future Implementing Arrangements to be agreed upon
by the parties.
This Implementing Arrangement is specifically
focused on: a) providing technical consultation
and software for the operational implementation of
the WRF 3D-Var data assimilation system, and b)
performing GPS radio occultation data assimilation
experiments and assessing its impact on typhoon
prediction.
The technical cooperation to be undertaken under
the auspices of this Implementing Arrangement is
defined by the following tasks. Task details,
including specific work to be performed,
performance period, and estimated cost for each
task are contained in the attached Statement of
Work.
A summary description of the tasks to be performed
during this period is provided below.

Task #1 - Technical Support for the Operational Implementation
of WRF 3D-Var /NFS at TECRO's Designated

Representative, CWB
The WRF 3D-Var data assimilation system, developed by
AIT's designated representative, UCAR, will be
implemented into the operational environment of
TECRO's designated representative, CWB. TECRO's
designated representative, CWB, will be provided
support as necessary by AIT's designated
representative, UCAR, to ensure successful operation
of WRF 3D-Var at CWB. UCAR will provide technical
assistance on: (i) retrospective experiments in CWB
operational environment, (ii) ingest of CWB's typhoon
bogus data into the WRF 3D-Var system, (iii) ingest of
global model bogus data into the WRF 3D-Var system,
and (iv) background error statistics (BES) derivation
based on WRF 3D-Var/NFS.

Task #2 - Assimilation of GPS Radio Occultation Data for Typhoon
Prediction Using WRF 3D-Var System

AIT's designated representative, UCAR, will assist
TECRO's designated representative, CWB, to implement
the basic capability for the assimilation of GPS RO
data into WRF 3D-Var. This would include the testing
of local refractivity operator, the calculation of
observation errors, and implementation of data quality
control procedures for the GPS RO data. CWB and UCAR
will collaborate on performing GPS RO data
assimilation experiments using historical data that
are available from the CHAMP mission. CWB and UCAR
will also collaborate on the implementation and
testing of a typhoon bogus vortex procedure.

Task #3 - Continued Interaction on WRF 3D-Var System and GPS RO
Data Assimilation

AIT's designated representative, UCAR, will continue
to develop the WRF-based data assimilation system.
Continued CWB/UCAR interaction is important to keep
CWB staff up-to-date on current developments. This
task will allow continuing interaction at an
appropriate level, including new software releases of
the WRF data assimilation systems, exchange of visits,
copying papers and reports, and e-mail interaction.

ARTICLE IV - FINANCIAL PROVISIONS
In accordance with the Agreement, UCAR is
undertaking this work as the designated
representative of AIT. TECRO is required to
reimburse AIT for all costs incurred by AIT's
designated representative, UCAR, in association
with the project covered by this Implementing
Arrangement. AIT will transfer to UCAR all payments
made by TECRO to AIT for costs incurred by UCAR in
association with this Implementing Arrangement.
The total cost for activities described in this
Implementing Arrangement is mutually agreed to be
U.S. $195,000. TECRO agrees to transfer fifty
percent of the funds to AIT in advance, with the
remaining fifty percent to be transferred upon
completion of the tasks set forth in this
Implementing Arrangement No. 1. It is agreed and
understood that the payment will be provided in
U.S. dollars.

ARTICLE V - INTELLECTUAL PROPERTY CONSIDERATIONS
Intellectual Property - The parties agree that no
Intellectual Property or other Proprietary
Information will be provided under this Implementing
Arrangement. Intellectual Property and Proprietary
Information are defined as software, designs,
processes, drawings, data, and modeling systems
which includes, but is not limited to, all versions,
derivative works, updates, improvements,
modifications, enhancements and releases thereof,
patents, patent applications, continuations-in-part,
inventor rights in the United States and any foreign
countries and applications therefore. In the event
that any activities under this Implementing
Arrangement require the use of the other party's
Intellectual Property or Proprietary Information,
the parties shall in good faith enter into
negotiations to reduce to a mutually agreeable
writing the obligations and terms associated with
such understandings.
Public Domain Technology - The Weather Research and
Forecasting (WRF) model as well as its associated
data assimilation systems (e.g., 3D-Var) are
developed by the National Center for Atmospheric
Research (NCAR) with significant participation of
the broad scientific community. The WRF model and
WRF 3D-Var are in the public domain. Both parties
agree that the WRF model and WRF 3D-Var system and
any modifications, revisions, enhancements, updates
or improvements shall remain in the public domain
and are not considered Proprietary Information.

ARTICLE VI - EFFECTIVE DATE, AMENDMENT, AND TERMINATION
This Implementing Arrangement takes effect 1
January 2005 and the completion date of tasks
described in this Implementing Arrangement is 31
December 2005. This Implementing Arrangement may be
amended and/or terminated in accordance with the
terms and conditions of the Agreement.
