Copernicus Sentinel-2 observation in low illumination conditions over Northern Europe and Arctic Areas

17 October 2019

On the 23 October, the observation scenario of Copernicus Sentinel-2B will be extended including the acquisition of Northern Europe and Arctic Areas in low illumination conditions (sun zenith angles up to 85°).

As explained in the Copernicus Sentinel-2 Level-2A Data Quality Report, Level-2A products should not be used for quantitative/scientific analysis when produced from observations acquired with a sun zenith angle (SZA) above 70°.

Also of note is this particular feature can be diifferentiated in the products by means of the metadata item referred to as Level-2A_Tile_ID > Geometric_Info > Mean_Sun_Angle, reported in the tile metadata file (at location GRANULE/<tile-folder>/MTD_TL.xml of the product structure).

An updated observation scenario has already been published, and the Copernicus Sentinel-2 acquisition plans are also available.
