Copernicus Climate Change Service - C3S 512

Evaluation and Quality Control of the Copernicus Climate Change Service

The Copernicus Climate Change Service (C3S) aims to provide high-quality information about the past, present and future climate in Europe and the rest of the world. This would not be possible without the role of the Evaluation and Quality Control (EQC), which ensures these data is provided to a broad range of users while shaping the research agenda to attend the most important challenges detected. Thanks to the EQC help, the services provided by C3S are up to date and in unceasing evolution. This project is framed within the EQC's activities to ensure the quality of the datasets within the Climate Data Store (CDS).

In particular, this project tries to develop a solution for the EQC function to respond to the needs identified in previous contracts, through a regular user-engagement process. The project is lead by BSC (Barcelona Supercomputing Centre) and involves several institutions. We are more than proud of being one of them.

Our main contributions to this project are:

  • KPI definition: defining the indicators that signal a good performance of the service is key. Such metrics will inform C3S about the overall quality of the service, enabling them to take strategic decisions in the future. We have been strongly involved in the discussions to select the technical
    KPIs that better fit the service needs.
  • User interaction: we have developed the rating widgets within the CDS, to directly interact with users at key points of the platform use. These enables C3S to obtain valuable insights into how their users perceive their platform, and take decisions accordingly.
  • Dashboard implementation: To showcase the KPIs, we have implemented a dashboard that shows the most useful metrics, both for C3S users and C3S staff. It enables to compare current performance with past performance, and download historical results. It can be consulted here.
  • Quality control: We have taken part in the development of QARs (Quality Assessment Reports), an internal tool that C3S uses to ensure the CDS's quality.
  • CMS development: we have created a Content management System that enables the whole project and the C3S to create QARs in an easier and standardised manner.
  • Automatisation of the KPIs: we developed reKPIlator, a software capable of generating and updating over 80 relevant KPIs automatically, sorting through the millions of events that the CDS compiles from their users. We also developed rendermeter: an additional solution that uses Selenium to asess the performance of the CDS webpages. In this way we're able to distill the most relevant information, so C3S can take data-based decisions.

The details of the project, split by the different Working Packages (WPs) can be consulted below.

WP1: Fitness of the CDS data

The Climate Data Store (CDS) is the cornerstone of the C3S infrastructure, contributing to the provision of existing datasets on Essential Climate Variables (ECVs), climate analyses, projections and indicators. The CDS offers a web-based and API-based search to access all this climate data.

The CDS datasets must be compliant with certain data models, conventions and standards recommended by ECMWF, that is, the Common Data Model (CDM). We are involved in the planning and development of the Data Quality Checker: a product that checks if those datasets are in fact compliant with the CDM.

The CDS quality is fed by some tools called QARs. They are created to gather main information on all aspects of the object to be quaility controlled (e.g. ECV) in a standardised and concise form, whereby data users can be supported in making informed decisions on the use of multiple similar quality controlled objects (e.g. ECV) for their particular application. We have created a Content Management System that helps developing QAR content.

WP2: Fitness of the CDS toolbox

The CDS Toolbox is a comprehensive set of software which enables users to develop custom-made applications, helping them discover and process the data and products provided through the distributed data repositories.

Within this WP, we are engaged on the definition of shared vocabularies and common practices to ensure consistency of quality assurance information and user guidance for all elements of the CDS Toolbox.

WP3: Fitness of overall service

In order to check the fitness of the overall service, some KPIs where defined. At Predictia, we have established a workflow and a system to automatically revise and update these KPIs. In this case, we have developed a web dashboard and interaction system with C3S users, to gather their feedback. We are also reporting about the overall KPIs quality.
