Himalaya to India

One of the first published images (publishing started on November 17th) of Sentinel-3A SLSTR L1 NRT products. Those images are mosaics composed by three consecutive SLSTR products. The first image is an RGB composition of three bands: 0.555, 0.865 and 1.61 µm, where only the first band belongs to the visible spectrum (the other ones

Persian Gulf and Arabian Desert

This RGB image of the Persic Gulf and the southern part of the Arabian peninsula is a mosaic of two different Sentinel-3A OLCI L1 products. Those full resolution frames have a resolution of around 300 meters and are joined and reprojected in the World Geodetic System S3A_OL_1_EFR____20161020T063425_20161020T063725_20161020T090536_0179_010_077_2520_SVL_O_NR_002.SEN3 S3A_OL_1_EFR____20161020T063725_20161020T064025_20161020T084419_0179_010_077_2700_SVL_O_NR_002.SEN3 https://scihub.copernicus.eu/ Contains modified Copernicus Sentinel data 2016

Turkey and Cyprus

One of the first images of S3-A, after the product publishing started on October 20th, 2016. The image is an RGB processing, generated from an OLCI L1 product, using three bands: 681.25 nm (red), 560 nm (green) and 442.5 nm (blue). The reprojection is performed using the WGS 84 coordinate system: it is possible to evaluate the geolocation
