GEOWOW Vision ooooo

  • A long-term vision for GEOSS - GCI evolution…

  • …considering feedback from all the stakeholders___

  • More user categories

  • data providers, data specialists, multidisciplinary scientists, decision makers

  • More flexible architecture

  • community components, resource enablers, innovation opportunities


A vision for geoss
A vision for GEOSS

  • Present situation

    • expert scientific advice identifies the required datasets

    • discovery: from the GWP the datasets of interest

    • downloadsof individual datasets to local computing

    • heavy algorithm management & chaining for each host workflow & data input

  • Future GEOSS operations ?

    • expert scientific advice identifies the required datasets

    • assembly: needed datasets are assembled on demand into the GEOSS infrastructure (into a cloud?)

    • data as a service can live & remain ‘in the cloud’, for the application of algorithmsand calculation of indicators

    • repeatable environments allow for easy updates (in time or with new concepts) & scientific sharing


GEOWOW components/enablers

  • Components for Enhancing data discovery and access [Brokering Framework Evolutions] including result ranking and semantic-enriched search

  • Components for Developing Enablers* [Developer CloudSandbox, Cloud Controller],for the development of geo-processingcomponents that can interface HPC resources

  • *Enablers are customizable according to community-specific characteristics


Cloud Sandbox main concept

  • Think to …

  • …. a sandbox in a playground where children can play with bucket and spade to build a castle

  • A virtual work environment in GEOSS where scientists can use dedicated tools to build/test and run new models/algorithms, with the ability to retry and modify

  • A developer’s cloud sandbox includes also interfaces to Cloud services enabling data intensive analysis


Access to and sharing of

the sandbox service

The scientist can manage the sandbox service through a simple interface, e.g., defining input parameters, triggering the algorithm execution, monitoring the processing status

Community-specific clients are able to easily communicate input parameters, included input products, and invoke the execution of the algorithm (standard OGC WPS).

Developer Cloud Sandbox service

The sandbox environment is sharable among trusted communities for e-collaboration

Once the algorithm is “consolidated”

it can be shared with the wider GEOSS community as a SaaS e.g. through the WPS interface

The scientist can access in a secure way the sandbox service and code a specific algorithm



Catalyzing resources
Catalyzing resources

Support researchers to compute indicators for policy makers

Feed resources to Computing Clusters to run global & regional marine ecosystems assessments

Take-up for future commercial applications (under ad-hoc conditions)

Go through research oriented, not for profit, uses of TIGGE-LAM data in order to spread innovation

Expand uses of ESA satellites data

Development of new applications leveraging innovative uses of earth observations


Capacity building
Capacity Building

Ability to leverage ESGF’s CMIP5 Climate projections data, slice it and process it

Support reproducibility of scientific experiments & open science

Explore and visualize ECMWF data from integrated Cloud appliances

Improve accessibility of key TIGGE data for a wide user community and better support ECMWF partner users

Experiment with ENVISAT SCIAMACHY, global measuring of trace gases in the troposphere and in the stratosphere

Towards integration of Earth Explorers missions: catalogs & processors on Cloud Sandboxes


Data sharing
Data Sharing

Ocean Biogeographical Information System (OBIS)

Transboundary Waters Assessment Programme (TWAP) indices and indicators

TIGGE and TIGGE LAM, THORPEX Interactive Grand Global Ensemble Limited Area Model

ERA Re-Analysis archives

ESA Missions data (archived and Earth Explorer)

Earth System Grid Federation – Model IntercomparisonProject Phase 5 (CMIP5) data




#1: Vegetation analysis through MERIS time series

  • Exploring Large Earth Observation Temporal Series for Land Change Events Detection

  • Some samples products are copied in the “sandbox”

  • An SSH connection to the sandbox allow the scientist to implement the algorithm and define a workflow, installing any library of interest in the sandbox, e.g. “R”, MERIS toolboxes etc.

  • The scientist tests the algorithm on few samples

  • The scientist runs on the full dataset of interest (thousands of datasets) exploiting Cloud resources if needed

For an easy access to data, metadata and workflow management

R libraries


#2: Cryosatshowcase

  • Cryosat mission: three years of observations for climate research

  • ESA has prepared a Processor Prototype generating:

  • Radar Echogram

  • SSH, SLA (W/O SSB), SWH, sigma0, wind speed

  • The objectives of the experiment using the SANDBOX are:

  • to experiment in house research themes that will be further exploited in the ESA-funded R&D projects

  • to provide expert users with consolidated SAR geo-products to get acquainted with the novelties and specificities of SAR Altimetry


#3: SciamachyShowcase

Retrieval of Mesospheric Sodium densities from SCIAMACHY daytime limb spectral

  • The experiments allowed scientists to extent the results analysis obtained from a preliminary analysis (in the temporal frame 2002-2007) to the full archive of SCIAMACHY data (2002-2012) .

  • This gives the possibility to identify trends.

  • Furthermore this analysis may allow the possibility to define a new inversion model for more accurate vertical profiles.

  • Scientists are currently analyzing the obtained results.


Perspectives

Developer Cloud Sandboxes – What’s next

Perspectives


Coming next
Coming next

Have a focus on results dissemination: success stories, best practices, online tutorials & demos, and getting some external users on the GEOWOW Platform.
