Sentinel-1 in satellittdata.no


Co-visualized Sentinel-1 and Sentinel-2 imagery using the basket functionality for visualizing multiple files.

We are pleased to inform that Sentinel-1 Ground Range Detected (GRD) Extra Wide (EW) swath mode now are available in satellittdata.no/metadata_search. EW is the primary mode for use over sea-ice, polar zones and certain maritime areas covering large areas which are difficult to reach. The Sentinel-1 satellites carries a C-band SAR instrumet which is, among others, capable of acquiring radar-"images" of the earth surface independent of clouds in the athmosphere and sunlight. Hence, SAR is widely used for e.g. sea-ice retrievals, maritime monitoring and ice-berg detection. Read more about the Sentinel-1 constellation here

As for the Sentinel-2 imagery, the original Sentinel-1 SAFE products are converted into NetCDF/CF making it possible to do e.g. subsetting of the data directly utilizing OPeNDAP, as explained in other articles like this one.

The scenes visualized in the image above show both Sentinel-2 and Sentinel-1 scenes with ca. 7h time difference covering the same area. Click this link to inspect the products yourself (note: you must have a user account since we make use of the basket interface).

We will soon make Sentinel-1 GRD Interferometric Wide (IW) swath mode available as well.
