## NDBC’s DAC Roles

- Assembly and Distribution
- NWS Telecommunications Gateway
- NWS (AWIPS, NCEP)
- GTS
- Commercial Sector (Family of Services)
- Internet
- www.ndbc.noaa.gov
- dods.ndbc.noaa.gov
- Quality Assurance/Quality Control

**Notes:**
Webmaster mail shows WFO’s using web as well as AWIPS.

**NDBC MODEM Kit****(Meteorological and Oceanographic Data Exchange Module)**

- NDBC
- OPeNDAP

**Notes:**
NDBC’s DODS server expanded from pilot to operational source for NDBC and Observatory data, October 2004

## Assembly/Distribution Status

**156 NDBC buoy and C-MAN stations **
**76 regional observing system stations**
**~54 are COTS partner stations**

**Notes:**
Approximately 1/3 are non-NDBC stations.

## National Data Buoy Center: Data Management and Communications Center Data Volume 

**National Data Buoy Center:**** Data Management and Communications Center ****Data Volume**** **

**FY03 2,006,033 ****	**
**Observations Released**
**FY04 **_**2,237,984**_** ****	**
**Observations Released**
**11.6% over FY03**
**~25% over NWS base**
**FY04 1,787,132****	**
**NWS Observation Target**
**Observations Released **

- 72.8%

- 11.7%

- 15.5%

**Notes:**
Recent figures for management report - a good report card for both NDBC and the observatories.
Shows NDBC is facilitating more observations onto communications backbones.
Helps justify congressionally directed funding of observatories.
Will only get better – many stations added during FY04, more to come.

## NDBC’s DAC Roles

- Assembly and Distribution
- Quality Assurance/Quality Control
- Meteorological
- Realtime - automated
- Range, Time Continuity, Relational checks
- Daily – human/machine
- Tighter control limits, QC flag analysis
- GRIB/nearby station comparisons
- Plots and other graphics
- Monthly – Archive Analysis
- Ocean
- Needs Development

**Notes:**
NDBC has mature, respected QA/QC system for marine met data.

## Activity/Plans

- FY ‘04
- QARTOD Workshop
- FY ‘05
- Serve all data with OPeNDAP (and web)
- Enhancements to MODEM for other ocean parameters
- More COTS Partners using MODEM
- Standardize QA/QC for selected ocean parameters
- Prototype LAS server
- Improve metadata collection and sharing
- Outyears
- Rest of ocean parameters in MODEM
- Extend ocean QA/QC standardization
- Metadata improvements

**Notes:**
MODEM originally built for WMO data formats; 
will use XML for undefined WMO data formats.
GTS delivered version of data, not an archive center.

## Ocean QA/QC Plans

- Survey methods in use by community
- Establish standard processes
- Incorporate in DAC Realtime process

**Notes:**
Focus on water temp, salinity, and currents in FY05.

**Notes:**
We publish our met QC techniques.
Will do the same with ocean QC standards.

## NDBC COTS MATRIX

**Notes:**
Blue shows accomplished partnerships.
Rose shows FY05 goals-more partners, selected ocean QA/QC.
The rest in FY06, FY07.
Solicit updates, corrections, input.
