The need for an improved cloud detection method for Proba-V products was raised already during the first Proba-V Quality Working Group Meeting, held in ESTEC on March 2015. This need was additionally underlined during the last Proba-V Symposium, held in Ghent on January 2016, as being one of the major issues to be addressed for improving data quality. Several presenters at the Symposium reported under-detection of clouds with the current algorithm with semi-transparent clouds representing a major concern for land cover applications as well as for surface properties retrieval.
In order to answer to this need, ESA in collaboration with BELSPO decided to organize a Round Robin exercise on Proba-V Cloud Detection. The Round Robin will be open to any interested user with the goal to provide recommendations for the definition of the future operational processor baseline.
The objectives of the Round Robin exercise are:
Round Robin setup
A summary table providing the main requirements and settings for the Round Robin exercise is provided here:
The Proba-V Cloud Detection Round Robin will be performed according to this plan.
A fixed price reward is allocated for each algorithm provider. The reward will be granted upon provision of the following deliverables:
The Quality Assessment will be performed by Brockmann Consult on the Validation Dataset and a final report will be prepared and reviewed among the Round Robin participants.
Results will be further discussed during a dedicated one day workshop in ESRIN.
Final peer-reviewed paper will be prepared summarizing the results of the inter-comparison. Co-authorship of the paper will be granted to the Round Robin participants.
