Data Access Portfolio 2014-2020:
Two Dataset types, and 3 Access types
• CORE datasets: continuous data delivery from systematic missions, predefined large
coverages or regular repetitive coverages, to serve a large variety of Service providers;
• ADDITIONAL datasets: 40 data type categories to meet specific requirements of
Copernicus Users; “on-demand” datasets, activated through ordering by Users who
are granted a quota. Data available for re-use by eligible user categories.
A.
B.
C.
DISCOVERY : search for spatial datasets and services on the basis of the content of the
corresponding metadata and display of the content of the metadata.
VIEW : The VIEW service shall make possible, as a minimum, to display, navigate, zoom
in/out, pan, or overlay viewable spatial data sets and to display legend information and any
relevant content of metadata
DOWNLOAD : access to full products as supplied by CCMs, to process to higher levels.

Highlights from an initial experts
assessment
Room for improvement
1. Data Interface
• Filter by clouds, higher res. QLs
• Product names/ length (windows!), more info into XML files
• Subselection/subsetting (area, bands, individual tiles)
2. Data quality
• Increase data quantization: spread to 10.000 (1000 values today)
• Crosstalk (to be applied to all SWIR bands), esp. for B10
• S2 tile grid minor corrections
• DEM harmonisation with Landsat?
• Improve SNR for coastal?
3. More functionality and intuitiveness in S2toolbox
4. Comparability with Landsat, mostly in geometry
Recommendations
on future S2s
S2B:
- Importance of the 2nd unit Sentinel-2B to be launched ASAP
- Importance to generate systematic L2A!
S2 next generation:
- Thermal infrared!
- SWIR channels in 10m!

Observation scenario
1. Currently observation of average 9 min/orbit (i.e. 40% of average observation time
in full operations) =~ Europe+Africa systematic, plus selected cal/val sites across
the globe
2. After IOCR, the initial scenario foresees to
–
Systematically acquire Europe & Africa
–
Acquire the rest of the world within a certain time interval: this interval will
be progressively reduced over the coming months to reach 10 days
3. The observation plan will be published ahead of every repeat cycle at
https://sentinels.copernicus.eut/web/sentinel/missions/sentinel-2/operations-ramp-up-phase
4. It will fulfill the needs of Copernicus users, as well as the objective to compile the
Global reference image, allowing to minimize multi-temporal geolocation errors
