The ESA Validation Data Centre (EVDC) serves as a central, long-term repository in Europe for archiving and exchange of correlative data for validation of atmospheric composition products from satellite platforms. EVDC builds on the previous ENVISAT Cal/Val database system in operation at NILU since the early 2000s, and provides tools for extraction, conversion and archival of a large amount of EO data.
The objective of the EVDC is to provide an online information system that supports users in managing and exploiting campaign datasets for Earth Observation missions and applications.
Skytek has teamed up wth NILU & ICHEC to improve on the current system and to extend the use for ESAs new Sentinel satelite data.
A number of tools exist in EVDC to aid the users in converting and submitting their files in accordance with the metadata standards that were established for atmospheric and oceanographic data for ENVISAT validation in 2002. This metadata standard has evolved in collaboration with the NASA AVDC (Aura Validation Data Centre), NDACC (Network for the Detection of Atmospheric Composition Change) and related universities and organisations into the GEOMS standard.
The database helps as a tool to monitor the quality and availability of the data provided by the data acquisition teams contracted by ESA, and it aims to support field campaigns over various seasons and latitudes.
