The European Space Agency is working on a family of satellite missions called the Sentinels. These missions are owned and managed by the EU as part of the Copernicus programme, that is said to be one of the most ambitious Earth observation programmes to date. It aims to give timely, accurate and accessible information for better environmental management.
Each of the six missions carries specific instruments for observations:
Multispectral sensors (Sentinel-2)
Instruments to measure land and ocean surface temperature and colour (Sentinel-3)
Four out of six missions are operational at the moment.
Sentinel data is open and easily accessible. Here we will give a small cheat sheet of various services connected to these missions.

ESA provides a set of tools to work with Sentinel data. They can be downloaded here.
The Sentinel-1 Toolbox is a collection of processing tools, data product readers and writers and a display and analysis application to support the large archive of data from ESA SAR missions. The Sentinel-2 Toolbox is a set of visualisation, analysis and processing tools for the exploitation of MSI data from the Sentinel-2 mission. Similarly, the Sentinel-3 Toolbox is made for OLCI and SLSTR data.
If you’ve used these tools, we would appreciate some feedback.
Sentinels Scientific Data Hub is a web based system designed to provide remote sensing data users with distributed mirror archives and bulk dissemination capabilities for the Sentinels products. The Hub provides complete, free and open access to Sentinel-1, Sentinel-2, Sentinel-3 user products.
Data browsing portal (requires registration).
Sentinel-2 data is available for anyone via Amazon S3, either over Internet or within AWS API, more info here. All Sentinel-2 scenes are made available, often within hours of production.
Users can browse through the contents of the Sentinel-2 Amazon Public Data set via the Sentinel Image browser.
