Data Policy (1/2)Data Policy (1/2)

The Data Distribution Policy is effective for the first two years

FORMOSAT-3/COSMIC data will be provided at no cost or at the cost of reproduction and distribution.

A “data use agreement” is required for the use of data and products.

Users will register through Taiwan (TACC) site.

The review and approval are to be made jointly by both NSPO and UCAR.

28

Data Policy (2/2)Data Policy (2/2)

The neutral atmosphere data products will be distributed near real-time after processing to NESDIS which will distribute via the GTS to weather centers. All Data and Product are available each day for Science Research.The raw FORMOSAT-3/COSMIC data (e.g., GPS phase and amplitude data) will not be distributed in real time. Requests for the real-time raw data will be reviewed jointly by the NSPO Director General and the UCAR President. Some additional limitations may be placed on data products at the request of the specific Principal Investigator’s requiring data check-out times.

29

ConclusionsConclusions

Satellite I&T are progressing well. Ground system upgrade is completed.Mission operation simulation and training are on-going.Launch vehicle development is on track.Range operation activities are being coordinated.Launch target date is March 2006

Launch slot finalization still needs coordination among all parties.
