Open Access to GTS Update and Next Steps

JCOMM OCG Vice-chair for Data and Information
University of Washington/JISAO, NOAA/PMEL, Seattle, USA
2019 IOOS Data Management and Communications Meeting
Slide2Emerging OCG networks
Gliders
HF Radar
Animal Borne Sensors
JCOMM OCG Open Access to the GTS Project
Observations Coordination Group (OCG)
Slide3GOALS:
Provide ocean data producers a simpler method of distributing real time data globally via the WMO GTS infrastructure
Provide ocean data consumers a simpler method of accessing the data distributed via the WMO GTS
JCOMM OCG Open Access to the GTS Project
Slide4Status: Access to GTS data
ERDDAP services through Observing System Monitoring Center (OSMC) are being widely used
Increase in usage since WMO-mandated switch to BUFR
Global Drifter Program, ICOADS, etc
“Operationalizing” OSMC access services using ERDDAP
Moving to 1 year rolling access
Currently have several years available in var, with a 90 day higher performance dataset
Potential cloud access to this data
JCOMM OCG Open Access to the GTS Project
Slide5Continue to submit Saildrone mission data (AIRT, SST, BARO, RH) to GTS
Antarctic
TPOS
Arctic
Using Drifting Buoy BUFR template – not ideal
Canada and Europe (Meteo France, ECMWF) are using the data
Not sure about U.S.

Slide7Status: BUFR template for USV
Thanks to David Berry (National Oceanography Centre) and Jon Turton, a
draft BUFR template has been created
Uses many existing sequences
Hope to validate and submit to IWG-CM (Codes Maintenance) by end of month
Will Also need templates for Gliders and Animal Obs (??)
Possibly sequences for other parameters (BGC, for example)

Slide8Increasingly, IOOS RA’s are using ERDDAP to serve their data.
However, currently they also have to provide data to US NDBC in a one-off format for GTS distribution
In July, 2019, US IOOS and OCG representatives met with US NDBC to work out a plan in which NDBC harvests data from RA’s that will then be distributed to the GTS
Have had several meetings since then to devise an implementation plan
JCOMM OCG Open Access to the GTS Project
In Progress: OCG and US IOOS
The US IOOS 11 Regional Associations
Slide9Discussions have led to requirements for data providers
These include:
One platform per ERDDAP dataset
Must contain global attribute with WMO platform code
Can have other platform identification attributes, IE IOOS Asset numbers
Parameters not destined for GTS will have some sort of to-be-determined “exclude” attribute

In Progress: OCG and US IOOS
The US IOOS 11 Regional Associations
Slide10Initially, a few select US IOOS regions will integrate the workflow and harvesting scheme with NDBC
PacIOOS, AOOS
Discussions will continue at the annual US IOOS Data Management and Communication (DMAC) meeting in late April

Slide11JCOMM OCG Open Access to the GTS Project
Open Access to GTS and the community
Need to identify non-US National Centers who have access to GTS that are willing to leverage defined workflow
Irish Marine Institute, IMOS, BODC have expressed interest
There is a possible European Open Access to GTS project launched in conjunction with EMODNet (Patrick Gorringe)
VOS and Ocean Gliders are interested in pursuing data distribution via Open Access to GTS
At February IODE XXV meeting, representatives from Sweden, Portugal and Australia expressed a strong interest in using Open Access to GTS to place observations on the GTS
Slide12JCOMM OCG Open Access to the GTS Project
Open Access to GTS and WMO
Introducing the Inter-Programme Expert Team on Integrated Marine Meteorological and Oceanographic Services within WMO and IOC Information Systems (IPET-MOIS)
The mission of IPET-MOIS is to define a process for JCOMM to endorse Marine Meteorological and Oceanographic centers in participation with WMO Information System (WIS) and the future IOC Ocean Data Information System (ODIS)
IPET-MOIS has identified the Open Access to GTS project/workflow as a potential way to improve distribution of data on the WIS/GTS
IPET-MOIS will also be able to help identify regional nodes that may participate as Open GTS endpoints
These nodes will be certified by WMO through criteria IPET-MOIS defines
Slide13JCOMM OCG Open Access to the GTS Project
Open Access to GTS and WIS 2.0
Open Access to GTS as a WIS 2.0 demonstrator project
Aligns very well with WIS 2.0 principles
Adopting web technologies and best practices
Using URL’s to identify resources
Prioritize use of Internet as distribution mechanism
Leveraging web services to access data and metadata
Eventually, eliminating use of routing tables and bulletin headers
Slide14JCOMM OCG Open Access to the GTS Project
Open Access Strategy document
Document designed as guidance and implementation plan for operationalizing Open Access to GTS
Small WG formed
A first draft has been reviewed and 2
nd
draft in progress
Will build off of US IOOS experience
Need a formal strategy for WIS 2.0 demonstrator project
