    Ship trails in the Bay of Biscay observed using PROBA-V imagery

    Ship trails have been perceived as convincing evidence of aerosol-cloud interaction. Ship emissions have been proven to contribute by about 1.9% and 2.9% to the increase in the global total and fine-mode aerosol optical thickness (AOT) respectively over a five year period (Peters et al. 20212).

    Satellite data boost global understanding of land surface

    Understanding our changing land surface is essential in the study of climate change. Satellites are used to monitor changes to the material that covers Earth’s surface, so-called land cover, such as vegetation and water.

    PV-LAC-COAST-RBD-v1-1.pdf

    The aim of this document is to make a critical review of the algorithms for TSM retrieval and atmospheric correction in turbid coastal waters, to identify the most suitable method (TSM and A/C method) for PROBA-V, to define the validation approach (including identification of the validation data and test sites) and to assess the utility and benefits of 100m coastal products through interaction with the user community.
