Explanation:

Copernicus programme is the world’s largest single earth observation programme directed by European Commission in partnership with the European Space Agency (ESA). It aims at achieving global, continuous, autonomous, high quality, wide range Earth observation capacity.
It provides wide range of applications like climate change, ocean, land and atmosphere monitoring as well as support in forecasting, management and mitigation of natural disasters. Its full, free and open data policy has proven its merits and allowed development of thriving user base in Europe and beyond.
Learning: Under this arrangement, EU will provide India with free, full and open access to data from Copernicus Sentinel family of satellites using high bandwidth connections from data hub to data hub.
Reciprocally, India will provide Copernicus programme and its participating states with free, full and open access to data from ISRO’s earth observation satellites including historical data sets.

This comprises data from land, ocean and atmospheric series of ISRO’s civilian satellites (Oceansat-2, Scatsat-1, Megha-Tropiques, SARAL, INSAT-3D, INSAT-3DR) with exception of commercial high- resolution satellites data.
The agreement also envisages technical assistance for establishment of high bandwidth connections with ISRO sites, in particular through setting up of mirror servers, data storage and archival facilities.
