Argo StatusArgo TC, M. Belbeoch


What is JCOMMOPS ?

• IOC/WMO coordination, monitoring and support centre for the sustained elements of the GOOS (Argo, DBCP, OceanSITES, SOT, GOSHIP, GLOSS)

• 6 staff• Information System• ~800k$/y budget• Supported by Ifremer&CLS, 20 Member States, France/Britanny, EU


Member States28 Countries operate floats, and Argo is reaching new record with 3918 active floats.


Operational Status


4000 or 3700 ?

• ~4000 units currently operating• 3700 reaching users as of Sept. 2015.

– 80 iced over– 160 pending (data distribution or location)– 60 have locations but no profiles, or are beached, greylisted, etc.

• 3200 in the core array (i. e. NO OVERSAMPLING)

• Platform life cycle @jcommops:– Probable (will to deploy a float with approximate x.y.t)– Confirmed ( ship/cruise identified)– Registered (all metadata ready. formally notified)– Active (sending pulses within defined time window)– Operational (delivering good data at gdacs)– Inactive (no pulses)– Closed ( no chance to come back on line).

Enhancements

• Additional funding not in sight for all expansions

• Logistics challenge for SO

• Diplomatic challenge for Marginal Seas and key EEZs (ex. Pacific) => cooperation required

• All requirements for Global Argo mean more than 6000 floats ?

NetworksFirst deep Argo floats (ARVOR_D, NINJA_D, SOLO_D) are operating.


Density (core)56% of the core array is well (or over) sampled.


Density/Age (core)49% if we consider decimal floats (weighted by their probability to die).


Density/Age (core)Spatial analysis allows to identify hot/cold spots and highlight gaps.

In particular, below 45°S in Indian and Atlantic.


Density 6° x 6°For the Global array, Southern Ocean remains the challenge.


Density/Age 6°x 6°

Deployment Plans ScoreUse the following map to optimize your deployment locations if required.


PlansPlease provide your draft plans as soon as possible (any format is accepted).

Standrda JCOMMOPS txt format is gradually used by all programmes:

ID (any);WMO (if exists);LAT;LON;DATE;SHIP;CRUISE


Action!!!

• Provide draft depl. plans to JCOMMOPS– Format= ID;WMO;LAT;LON;DATE;SHIP,CRUISE– Maintain same file on a yearly basis

• Important for Argo (international, national, regional)• Important for JCOMM integrated perspective

• Auto loading of: Argo netCDF file, US metafiles, JCOMMOPS text

• TC can help! Send me the info in any format.

• Use new JCOMMOPS website to do your planning– We will adapt tools to your requirements

• Do you need netCDF editor to create file when registering ?


Kaharoha’s contribution~20% of the active Argo array is implemented by one NZ ship (charter)


Metadata

• SHIP unique code ready !– New reference table– Requests to JCOMMOPS for additions– JCOMMOPS – ICES/BODC/Seadatanet

• DEPLOYMENT_PLATFORM (ideally std table)– KAHAROA

• DEPLOYMENT_PLATFORM_ID – 61LY (std table)

• Maintained by JCOMMOPS/ADMT with other ref tables– Governance of reference tables?

• API soon available to be used by GDAC checkers


Member StatesActually more than 150 additional floats are registered but no data is available yet.

Argo has certainly more than 4000 units in the ocean.


Member States (zoom)France is just the 2nd float operator after USA.


Market


Market« New » float manufacturers (SBE and NKE in particular) keep increasing their market.

Iridium (and BioArgo) seem stabilizing.


ProfilesDelayed mode quality control still remain a challenge

(% achieved keeps decreasing slowly).See J. Gilson charts for more details.


Profiles Quality (Sep. 2015)A quick view on 2015 3rd quarter profiles quality.

90% of profiles produced are « good ».


What is a good quality profile ?

• PRES >= B AND TEMP >=B AND PSAL >=B ?

• Clear logic rule required to build a good performance indicator


Delays

• Finally monitoring both GDACs• Problem detected at FR GDAC early 2015

– Fixed thanks to JCOMMOPS archive• Full Excel available for meeting• Target (90% within 24h ?)

Timeliness 89% (GTS)81% (GDACs)

Delays 7h, 25h (GTS)11h, 35h (GDACs)

Reliability


Argo / not Argo ?

• Need a clear policy. Challenging.• Need to sort out the existing (not only new ones)

• Not only GDAC data issues …– International regulations (transparency)– Best practices (cycling, sampling, beached floats retrieval)– GTS RT distribution for most of operational users

• Some metadata should tag clearly floats to make the difference with Argo, R&D and « non core Argo » floats

– Preserve the « Argo label quality »– Allow interoperability for data validation, reliability tracking, transparency– Allow some diversity

• New metadata? ARGO_GROUP?• New directory (hidden to public users) at GDACs? « Quarantine »


Summary & Challenges

• High level of international cooperation– Missing new key national partners– Need help from civil society?

• Contributions from major players is likely to decrease (US, Japan, Australia) due to flat (< inflation) or decreasing funding

• Europe or Asia won’t likely compensate this

• Good diversity of industrial partners– Float reliability not progressing anymore - won’t compensate neither– Diversity required for sensors, and telecommunication systems



• Well established data system (advanced data/metadata format)– Major format upgrade (sensors diversity)– Continuous efforts to provide a high quality dataset (70% DMQC achieved)– Seek convergence between GTS/WIGOS, GDACS, Seadatanet (e.g.)

metadata reference tables– Keeps improving delays but progress required for some DACs– Check NOAA/OSMC feedback on CF compliancy

• Increasing data uptake– Do we know well our users ?– Do we prepare the future ?– Need to keep innovating and move from dir/files to the cloud/API – ERRDAP installation at both GDACs could be simple addition



While Argo will probably reach a top in 2015, a degradation of the array in the next years is anticipated

Thank you.
