What is QA4ECV?

The FP7 QA4ECV project was initiated in 2014 to demonstrate how reliable and traceable quality information can be provided for satellite and ground-based measurements of climate and air quality parameters. The project developed and applied a Quality Assurance framework on new and improved multi-decadal data records of the Land ECVs Albedo, Leaf Area Index (LAI), and Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), and of the Atmosphere ECVs nitrogen dioxide (NO2), formaldehyde (HCHO), and carbon monoxide (CO).

We encourage you to browse through the website and survey the scope of QA4ECV activities. Of particular interest are the buttons ‘ECV DATA’ and ‘QA SYSTEM’ in the top menu. The ECV DATA provides free data access to harmonized, state-of-science multi-decadal records of ECVs (1982-2016 for Land, 1995-2016 for Atmosphere). QA SYSTEM allows data producers to embed detailed QA information for their product, and helps users to check the fitness-for-purpose of the QA4ECV data for their applications.

In early 2018, five EU-FP7 Space Research Programme to scope and underpin the Copernicus Climate Change Service (C3S) have come to an end. The PI’s for these projects (QA4ECV, ERA-CLIM2, UERRA, CLIPC, and EUCLEIA) wrote a position paper arguing that follow-on research projects are vital for European climate services to remain state-of-the-art in the future. This follow-on research is more efficient if it takes into account the lessons learned from previous experiences described above (PDF).

QA4ECV is always seeking to improve its effectiveness in serving the needs of satellite data producers and users. If you have a specific problem for which you need information or assistance, please contact scientific coordinator Folkert Boersma (boersma@knmi.nl) or QA4ECV Land coordinator Jan-Peter Muller (j.muller@ucl.ac.uk).
