How does EFAS estimate the impact of an event? how can I know whether they system is fully operational? In which format are GFM output product layers available?] How frequently are GFM data updated?
Which web services (API) are available? https://land.copernicus.eu/global/faq How do I subscribe to upcoming products through the legacy product access portal? https://land.copernicus.eu/global/faq
How to credit GFM as data source in publications?

Why is there an overlap between Copernicus Sentinel-1 Level-0 products?
Level-0 (RAW) products constantly have an overlap at the beginning/end of each scene. The seconds of the overlap are described in the product annotation in the "generalProductInformation" section. The "s1sar:sliceOverlap" parameter is defined as follows:
"Overlap (in seconds) of input data between adjacent slices within the L0 segment to which the slice belongs (applicable if the current L0 product is a slice)" and it provides the information on the overlap between the consecutive products.
There are no overlaps between Level-1 images.
Where can I find detailed documentation on Copernicus Sentinel data products and algorithm descriptions?
Copernicus Sentinel technical guides are available here for each instrument.
Are there known Copernicus Sentinel-1 / GFM product quality issues?
Where can I find an update on the Sentinel-2 products quality?
How can I contact the Users’ Support Service? If your question wasn't listed, please refer to our Helpdesk.
