13SUBCOMMITTEE ON HYDROLOGY
- Satellite Telemetry Interagency Work Group
-
- Major Activities in 2004 ( cont. )
- GOES DCS Improvements
- Members participated in NESDIS-sponsored meetings
with manufacturers of equipment for GOES DCS - Helped develop a list of long-term potential
improvements that included - Reduction of the the frequency range currently
used by HDR DCPs by ½ which would double the
capacity of GOES DCS. - Use of the GOES DCS interrogation link for 2-way
communications with remote sites.
14SUBCOMMITTEE ON HYDROLOGY
- Proposed Motion on Maintenance of the Present
Streamgage Network - Background
- Importance of streamflow data to protection of
life and property as well as effective water
resources management. - Network is heavily funded by USGS partners and
this funding is subject to substantial year to
year fluctuations. The result has been loss of
some key stations in recent years. - Reliance of other agencies and organizations on
this data. - Recommendation
- Maintain the program at or above its present
level - USGS remain the agency responsible for operation
