I am very happy to share the news of the opening of Sentinel-2A data access on the Scientific Data Hub on https://scihub.esa.int/ Up to now only data acquired after the 28th of November are available, but ESA says :
We will also reprocess any useful data from the Commissioning Phase and the recent weeks after IOCR, and gradually populate the Hubs with those data. However, the reprocessing campaign for data acquired during and aftercCommissioning Phase, is foreseen to be finalised in Q2/2016.
This is not perfectly good news, as we will have to wait for quite some time to get these data. To get more information from ESA :
The Sentinel-2A data quality status can be found here.Sentinel-2 is currently in its Ramp-up Phase, milestones can be found here.With an average of 10 minutes MSI sensing time per orbit, Sentinel-2A is currently acquiring Europe and Africa systematic on every orbit, while the rest of the sunlit world land masses between 56 degrees South and 84 degrees North will be mapped with a 30 days revisit time. A new version (V2.0) of the S2 toolbox is available at http://step.esa.int/main/download
Congratulations to the whole S2A ESA teams (and their partners, including CNES) for this achievement !
