The Sentinel-2 mission is a land monitoring constellation of two satellites that provide high resolution optical imagery and provide continuity for the current SPOT and Landsat missions. The mission provides a global coverage of the Earth's land surface every 5 days, making the data of great use in on-going studies. L2A data are available in Europe from November 2016 and from January 2017 globally.
Each file is its own object in Amazon S3. The data are organised per tiles using the Military grid system (latest KML file). The basic data format is the following:
tiles/[UTM code]/latitude band/square/[year]/[month]/[day]/[sequence]/DATA
For example, the files for individual scene are available in the following location:
s3://sentinel-s2-l2a/tiles/10/S/DG/2018/12/31/0/
Where:
[UTM code] = e.g. 10 - grid zone designator.
latitude band = e.g. S - latitude band are lettered C- X (omitting the letters "I" and "O").
square = e.g DG - pair of letters designating one of the 100,000-meter side grid squares inside the grid zone.
[year] = e.g. 2018 - is the year the data was collected.
[month] = e.g. 12 - is the month of the year the data was collected (without leading zeros).
[day] = e.g. 31 - is the day of the month the data was collected (without leading zeros).
[sequence] = e.g. 0 - in most cases there will be only one image per day. In case there are more (in northern latitudes), the following images will be 1,2,…\.
DATA - data for each tile are organised as in original product S2 MSI Product Specification.
The metadata of the product, which tile is part of, are available in parallel folder (productInfo.json contains the name of the product). This can be found in products/[year]/[month]/[day]/[product name].
If you use the AWS Command Line Interface, you can list data in the bucket with the “ls” command:
aws s3 ls s3://sentinel-s2-l2a/
The data is in Requester Pays S3 bucket.
Some meta-data is available over HTTP proxy, find more details here
