CHARMe: Sharing knowledge about climate data

1. CHARMe is now available!

CHARMe went live early in 2015 and is supported by EUMETSAT CM-SAF, ECMWF and KNMI (links).

2. What does CHARMe look like?

Watch this video for a walk-through of the CHARMe system by one of the developers.

3. CHARMe Brochure

A CHARMe brochure outlines CHARMe's benefits for scientists, data providers, consultants, and users of Copernicus climate services.

4. The CHARMe system

The CHARMe system code (node and plugin) is available for developers here.

Are you a user or producer of climate data?

Do you want to see a simple way of judging if a dataset is fit for the user's purpose?

If so then you are a potential CHARMe user.

The CHARMe System...

allows users to view or create annotations that describe how climate data has been used and what has been learned. This information can include:

  • Citations that reference a particular dataset;
  • Results of assessments - reanalysis, quantitative error assessments;
  • Provenance - processing algorithms and chain data source;
  • External events that may affect the data - volcanic eruptions, El Nino, sensor failure;
  • Supplementary dataset quality information - maturity, discontinuity, updates.

CHARMe provides...

user with different kinds of supporting information, or metadata, to fully understand climate data.

The CHARMe system will collect and share annotations associated with climate datasets. This information is called commentary metadata. Users will be able to add or view commentary metadata, complementing existing information from the data providers.

CHARMe stands for the 'Characterization of metadata to enable high-quality climate applications and services'. CHARMe system will provide links between datasets and citations and other commentary information using open standards such as Open Annotation. This approach is highly flexible and can adapt to changing user needs as the system grows.

How does it work?

The CHARMe system will provide links between datasets and citations and other commentary information using open standards such as Open Annotation. This approach is highly flexible and can adapt to changing user needs as the system grows.
