Slide1

Open Access to GTS Update and Next Steps

Kevin O’Brien

JCOMM OCG Vice-chair for Data and Information

University of Washington/JISAO, NOAA/PMEL, Seattle, USA

2019 IOOS Data Management and Communications Meeting

Slide2

Emerging OCG networks

Gliders

HF Radar

Animal Borne Sensors

JCOMM OCG Open Access to the GTS Project

Observations Coordination Group (OCG)

Slide3

GOALS:

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

Slide4

Status: 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

Slide5

Continue 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.

Slide7

Status: 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)

JCOMM OCG Open Access to the GTS Project

Slide8

Increasingly, 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

Slide9

Discussions 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

Slide10

Initially, 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

Slide11

JCOMM 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

Slide12

JCOMM 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

Slide13

JCOMM 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

Slide14

JCOMM 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
