What MyOcean catalogue offers for MSFD

Example search result North Atlantic

Example search result Mediterranean Sea

MyOcean catalogue: 107 products

• All 1-line descriptions would fit on 2 A4 Excel pages (next slide)

• Catalogue offers also texts + plan views preview to form a booklet• 9 products for optical/biological North Sea (4 products multiyear)• 8 products for optical/biological Med Sea (2 products multiyear)• No easy drilling down on all properties of the models like

• Spatial and vertical resolution• Time span• Data source composition: model, in situ, satellite (previous slide)

Example: North Sea model comparison Lenhart et al, 2010, JMS

MyOcean data types

MyOcean offers 4 groups of products relevant for environment.

Data source type is less important than being multi-year.

Archived analyses/forecasts, hindcasts, reanalyses, reprocesing

1. Non-assimilated model simulations• without data assimilation (free runs)

2. Assimilated model simulations• data assimilation with in situ only• data assimilation with in situ + satellite• data assimilation with only satellite

3. Remote sensing collections• pure satellite collations• data assimilation (OI) with in situ

4. Aggregations of in situ data• Homogenized regional aggregations

HYBRID METHODSTHEORY AND DATA

MyOcean data services: 3 INSPIRE levels• INSPIRE requires a 3-step availability of geospatial data

1. Discovery: without MyOcean authentication

> Yes: catalogue for interactive manual access

> No: web service: OGC CSW machine-readable catalogue service

2. View: without MyOcean authentication> Yes: view OGC WMS inside MyOcean webviewer (next slides)

> No: web service: OGC WMS layer into user applications. (next slides) Technically up-and-running, but not offered/supported.

3. Download: fully MyOcean authenticated download mechanisms

> Yes: manual OGC netCDF files via internet browser (ftp or GUI)

> Yes: automated OGC netCDF file machine2machine (M2M) download (ftp or python client for experts)

> No: INSPIRE and OGC download standards not offered: – OPeNDAP+ OGC WCS + OGC WFS + OGC SOS– OPeNDAP technically up-and-running but not offered/supported.

Inspire viewing service now offered in MyOcean viewer

NOT offered in catalogue: viewing service for external clients

Example: MyOcean WMS can be added to webGIS viewer of Royal Dutch met office

(although it already works under the hood, without service)

Foster local models over single top-down product

This North Sea OSPAR example shows: models and remote sensing need local refinements for ocean color:• MyOcean now offers a few central models

• Essential for boundary conditions for local models: continue• MyOcean should also facilitate dissemination of local models:

harvest models from all over Europe, like NOOS does• For MSFD local knowledge is essential: this local knowlegde is

only in implemented in local models.• For science: improve discrepancies global and local models

MyOcean: examples NOOS and ESA

• NOOS approach is good example for what MyOcean can offer MSFD: collect output from many tailored local models

• ESA CCI projects with round robins are good example for what MyOcean can offer MSFD: compare processing of many local remote sensing algorithms (Inherent Optical Properties, IOP) that differ per watermass, i.e. per area of 100x100km2 for turbid Case II waters like North Sea, Irish sea, Channel.

Example nitrate concentration for IT from MyOcean

Example river discharge for Med Sea

Summary

• MyOcean already offers products useful for MSFD• MyOcean should officially provide WMS service:

• viewing MyOcean products in client WMS viewers (INSPIRE requirement). Technically MyOcean already offers this, but unsupported.

• MyOcean should provide INSPIRE web services for grids in addition to manual/batch download mechanisms (OPeNDAP, OGC WCS, WFS). Technically MyOcean already offers OPeNDAP, but unsupported.

• WCS allows for requesting data at tailored local grids for easy local DPSIR analysis.• Foster MyOcean dissemination of dedicated models products already prepared for regional seas (e.g.

NOOS, ESA, OSPAR) • Suite of model results support assessment• Suite of remote sensing algorithms support assessment

• WG DIKE should play active role as end-user in MyOcean/ECOMF

Proposal of Workshop

Proposal: Organize a dedicated workshop to specifically discuss MyOcean products applications to MSFD implementation of GES indicators

Main topics• Overview of multiyear MyOcean products with focus on

resolution and level of confidence

• Central vs local models for MSFD subregions: boundary conditions, downscaling

• MyOcean product output representation: OGC WMS and grid (INSPIRE: OGC WCS, OGC WFS)

• MSFD GES indicator implementation

• DPSIR approach and programs of measures
