I recently published a paper about this

W3C OA is a natural fit for CHARMe……plus it lets us record motivation, tags, author, time, have multiple targets.

3rd party system

Data provider website

• CHARMe will create connected repositories of commentary information

• Annotations stored as triples in “CHARMe nodes”

• Information can be read and entered through websites or web services






Some advanced use cases...

Climate data users discuss about data:


Climate data users discuss about data:

- Intercompare datasets

- Research on events timing

- Focus on specific areas of the world


Plankton bloom: “when did it start?”



Sediment from rivers:“Where did it come from?”



Sediment from rivers:“Where did it come from?”Reflective bloom: “or is it an image artefact??”




Plankton tracing currents: “how deep?”




Plankton tracing currents: “how deep?”

Clear blue ocean: “isn’t it nice?”


Significant Event’s Viewer

Allows plotting of EO data on a timeline

Significant Event’s Viewer

Matching of events that may explain picks on the data

Fine-Grained Commentary Tool

Focus on user commentary Planned to expand the tool to cope with other kinds of metadata



Fine-grained commentary metadata: Targets are not entire datasets but subsets of them:

• An entire variable/field within a dataset• Time intervals or an instant• A pixel, a bounding box, a drawn polygon, an area of interest • A vertical section• A transect• A combination of the above

Allows visual data intercomparison Planned to expand the tool to cope with metadata intercomparison

Record a comment about…



… the entire SST field within a multi-variable gridded dataset.




… all SST data from 2006 from within a long gridded time series covering a given area.





… a particular pixel corresponding to the position of an in situ station






… a transect navigated by a scientific cruise who wants to start a conversation about their findings comparing their data with EO SST data







…. a vertical section from a pixel of interest in an SST dataset to compare with buoy measurements.







…. a vertical section from a pixel of interest in an SST dataset to compare with buoy measurements.

… the particular differences found in an area or interest between CCI SST and CCI Cloud data.


• Main Mockup for screen display distribution




• Mockup showing how to enter comments



• Mockup showing visual intercomparison

NCPP + CHARMe

• CHARMe aids evaluation of datasets and informs climate data users’ decisions – are we working towards the same objective?

NCPP + CHARMe


• Climate Translator + OpenClimateGIS similar to CHARMe Maps? Any prototypes?

NCPP + CHARMe



• What’s exactly the CoG Environment?

NCPP + CHARMe



• What’s exactly the CoG Environment?

• NCPP to provide standard-based evaluation capabilities. Can we use the same standards?

NCPP + CHARMe

• Can any of these benefit from the CHARMe Plugin?• Earth System Grid (ESG)• CIM Metadata Viewer and Comparator

NCPP + CHARMe

• Can any of these benefit from the CHARMe Plugin?• Earth System Grid (ESG)• CIM Metadata Viewer and Comparator

• Which are some problem specific case studies within NCPP environment? Can we build a customized tool for your users once the CHARMe System is in place?
