| description | The Copernicus programme, is a European initiative for the implementation of information services based on observation data
received from Earth Observation (EO) satellites and ground based information. In the frame of this programme, ESA is developing
the Sentinel-2 optical imaging mission that will deliver optical data products designed to feed downstream services mainly related to
land monitoring, emergency management and security. To ensure the highest quality of service, ESA sets up the Sentinel-2 Mission
Performance Centre (MPC) in charge of the overall performance monitoring of the Sentinel-2 mission. TPZ F and DLR have teamed
up in order to provide the best added-value support to the MPC for calibration and validation of the Level-2A processor (Sen2Cor)
and products. This paper gives an overview over the planned L2A calibration and validation activities.
<br><br>
Level-2A processing is applied to Top-Of-Atmosphere (TOA) Level-1C ortho-image reflectance products. Level-2A main output is
the Bottom-Of-Atmosphere (BOA) corrected reflectance product. Additional outputs are an Aerosol Optical Thickness (AOT) map,
a Water Vapour (WV) map and a Scene Classification (SC) map with Quality Indicators for cloud and snow probabilities. Level-2A
BOA, AOT and WV outputs are calibrated and validated using ground-based data of automatic operating stations and data of in-situ
campaigns. Scene classification is validated by the visual inspection of test datasets and cross-sensor comparison, supplemented by
meteorological data, if available. Contributions of external in-situ campaigns would enlarge the reference dataset and enable
extended validation exercise. Therefore, we are highly interested in and welcome external contributors. |
