Angular normalisation of PROBA-V 300m NDVI

This contribution describes an ongoing effort, within the framework of the Copernicus Global Land Service 1, to develop an updated PROBA-V 300m NDVI product. Unlike previous versions of the PROBA-V NDVI at 300m, a normalisation for viewing and illumination geometry is performed and its temporal compositing strategy is aimed to maintain near real-timeness as possible. We use the MSG/SEVIRI NDVI angular normalised time series with high temporal resolution (daily cadence) to evaluate the near real-timeness of the PROBA-V NDVI 300m compositing strategy. Since PROBA-V does not have on-board propellant, the overpass times are expected to gradually differ from the at-launch value. Therefore, an angular normalised PROBA-V NDVI 300m product becomes pivotal to ensure continuity with the Sentinel 3 missions.

Operational delivery of long time series of biophysical variables in the copernicus land service

The Copernicus Global Land Service is the achievement of more than 10 years of European R&D activities. It provides historic and NRT biophysical products useful for a wide range of applications. Its continuity and its evolution are ensured by the current research and innovation projects which are preparing the use of new EO missions data, including the future ESA Sentinels data.
